Magnitude 9 earthquake in Japan(1) Easily lead to nuclear radiation types of cancer?

Backgrounder: METI nuclear safety and security of homes 14 announced, Fukushima Nuclear Power Station Unit 3 in the first 11:01 local time, hydrogen explosion occurred, the reactor where the building was damaged, but placing the reactor vessel was not damaged. Currently, the Japan Atomic Safety and Security Institute called the first nuclear power plant in Fukushima within a 20 km radius around the 600 residents of the house quickly to the refuge.

As has happened in human history, the atomic bomb, nuclear power plant leaks and other serious accidents, it is more and more insight into the vast and cold nuclear radiation lethality. How terrible nuclear radiation in the end? Nuclear leakage, explosion, nuclear radiation on the environment, human health will bring a long time, an immeasurable impact, and because of cancer caused by nuclear radiation is the most significant of a performance.
Carcinogenic radiation path -
Nuclear radiation are α, β, γ are three forms of radiation. α radiation can be blocked as long as a piece of paper, but a large inhalation hazard; β radiation burns after skin is exposed to significant; γ radiation and X-ray similar to the human body and can penetrate buildings, hazard distance.
How does nuclear radiation damage the human body from? Human body there are a lot of various molecules, nuclear radiation on the human body is first expressed in the destruction of these molecules, causing molecular properties change. However, the damage does not necessarily mean "cancer."
Only when the molecules can not repair damaged cells remained alive and the case of eventual uncontrolled cell replication, and finally grow into cancer cells, are considered because the occurrence of nuclear radiation causes cancer. However, it is undeniable that for a long time to accept a higher intensity of radiation will increase the possibility of human cancer.
Hot friends: Japan nuclear leak would cause a new round of cancer highlight?
Easily lead to nuclear radiation types of cancer?
According to the information retrieval found that the current radiation foreign pathogenic events occurring in patients with multiple manifestations of fatigue, dizziness, insomnia, skin redness, ulcers, bleeding, hair loss, leukemia, vomiting and diarrhea. Serious nuclear radiation will increase the cancer, distortion, the incidence of hereditary disease. In general, the body more energy radiation received, the more serious symptoms of radiation sickness, carcinogenic, teratogenic risk is also greater. Among them, those most vulnerable to nuclear radiation leukemia, lymphoma, skin cancer, thyroid cancer and other cancers.
Leukemia: high frequency radiation may be due to microwave radiation causes cells to change the DNA sequence or mutations, in particular the dramatic increase in white blood cells may lead to sudden imbalance of the immune system. After the atomic bombings in Japan, a sharp rise in leukemia patients that are powerful burst of nuclear radiation effects on human cells.
Lymphoma: Radioactive substances that can cause chromosome changes in lymphocytes a long period of radioactive material if the chronic injury state, cell survival is still difficult to repair themselves, the increased chance of cancer cells.
Skin cancer: in the nuclear radiation environment for people, human contact with the outside skin is the most widely used place. The face of volatile substances or diffuse radiation material, the skin will bear the brunt of exposure to risk. In addition, the yellow and white compared to white skin are more susceptible to radiation damage.
Thyroid cancer: If a large number of radioactive material released into the atmosphere, easy to mess with hair thyroid cancer, because these radioactive materials represent a large share of radioactive iodine, and iodine in human thyroid is the main gathering place, when the body is eating or inhalation of radioactive iodine, accumulation in the thyroid dose of radioactive iodine can damage the thyroid gland or surrounding tissue, a dose may induce thyroid cancer.

Coca-Cola responded caramel events

Yesterday, foreign and Hong Kong media reported that the Center for Science in the American public (CSPI) released a research report, said the Coca-Cola and Pepsi and other beverages are widely used in food should be strictly prohibit the use of caramel, because these substances is very may be carcinogenic. In response, Coca-Cola said its caramel color used by the company and does not cause cancer.
According to yesterday, the British "Daily Mail", Hong Kong, "Lianhe Zaobao" and other reports, CSPI noted that Coca-Cola and Pepsi contained in a component may lead to cancer risk, should be "disabled." They raised concerns about the ingredient is a synthetic pigment --- caramel brown. The researchers pointed out that this pigment can lead to thousands of people suffering from cancer.
CSPI noted that this artificial caramel coloring, and use at home to cook a pan melt the sugar into caramel different, it is made of sugar, ammonia and nitrite in the chemical reaction under high pressure and temperature from the process, will produce 2-MI, and 4-MI of two chemicals. U.S. researchers found that 2-MI, and 4-MI in mice caused lung cancer, liver cancer, thyroid cancer or leukemia. CSPI urged the Food and Drug Administration, should be prohibited in the dark drink the use of ammonia caramel, soft drinks obesity is a major health threat to patients. Sugar and ammonia will produce a chemical reaction caused by carcinogens, and lead to cancer-causing thousands of Americans.
In response, this response to yesterday's Coca-Cola China, said: "Our drinks are completely safe."
"CSPI is irresponsible drinks in a statement questioned our use of caramel in the security, and no reason to provoke consumer concern about cancer. In fact studies have shown that our products will not be used in caramel cause cancer. "side said Coca-Cola, Coca-Cola contains only a reference to the compound by CSPI quality, the quality of this compound occurs in the cooking" browning reaction "(a common food discoloration), which substances in many foods and beverages contain.
In addition, yesterday responded to the American Beverage Association also said there is no evidence that the caramel compounds can lead to human cancer.

Housewives alert! Cleaning agents may cause infertility

Opportunities for women housework more than men in every day clothes washing, scrubbing pots and pans and disinfection, indoor insecticide and other household chores in addition to offensive, their skin and are suffering physical and mental health may be subtle influence of these chemicals infringement.
Skin damage
Washing powder, detergents, insecticides, toilet and other household spirits containing alkaline cleaning chemicals, blowing agents, fatty acids, protein and other organic matter, in which acid from the skin to suck out the water, so that protein coagulation; and alkali In addition to absorbing water exceptionally substances, but also enable organizations to protein denaturation and damage cell membranes, damage is more severe than acid.
Detergent contained in the cationic, anionic surfactant, to remove the oily protective layer of skin surface, and then the skin corrosion, damage to the skin are also high. Commonly used detergents can also cause facial appear Hudie Ban.
Immune dysfunction
Variety of chemicals in detergents can cause human allergic reactions. Some chemical substances into the human body can affect the lymphatic system, causing the body defenses are weakened; use clear fleas, termites, bedbugs and cockroaches in the pharmaceutical, would cause increased risk of lymphoma, human suffering; some of bleach, detergents, cleaning agents contain fluorescent agents, whitening ingredients, invades the human body, not - as easy as chemical composition is broken down, but accumulate in the human body, greatly reducing the human immune system.
Impede wound healing
Fluorescent agent but also to variability in human cells tend to occur, the cumulative toxicity in the liver or other vital organs, will be a potential carcinogen. Blood system damage: chemical substances easily contaminated human blood, although the blood has a certain self-purification capacity, into which small amounts of harmful substances will be diluted, decomposition, adsorption and discharge.
But the long-term, large amounts of toxic substances poured into the room will come to the qualitative change. Cleaning products in the chemicals into the blood circulation, will destroy the red blood cell membrane, causing hemolysis.
The source of blood contamination
Many compounds containing the essence of natural biological bath liquid, which often contain preservatives and other chemical substances, but also the source of blood contamination. Anti-moth-eaten clothes for the "camphor ball", the main component of coal tar naphthalene in isolated sperm. Long-term inhalation of camphor ball naphthalene gas, can cause chronic poisoning the body, inhibiting bone marrow function, people suffered from anemia, liver dysfunction and so on.
Increased risk of leukemia
According to the data show that women in the family placement of pesticides, the risk of leukemia than the absence of such items at home twice as high. Damage to the nervous system: some of the air cleaner in the synthetic aromatic substances contained in the nervous system can cause chronic poisoning, cause dizziness, nausea, vomiting, loss of appetite and other symptoms.
Pyrethrum insecticides containing toxic substances used to kill flies and other insects in the resin generally treated with dichlorvos, these toxic substances can be neurotoxic and induce cancer. Mix different types of cleaning agents may lead to more serious consequences. Reproductive system damage: chemical thinners, detergents containing chlorides most. Chloride in excess, can damage the female reproductive system.
Infertility
Detergents hydrocarbons, can cause loss of function of ovary; alkyl sulfonates such as chemical composition can be absorbed through the skin and mucous membrane. If pregnant women are often used, can cause degeneration of the egg, egg death. Scientists in the study of infertility process, discovered that many women are closely related infertility and long-term use of detergents. In the early stages of pregnancy, detergent chemicals also caused some of the risk of fetal malformations.
In view of household cleaners are many health hazards for women, women should pay attention to self-protection, usually should minimize the chance of exposure to chemicals. When using cleaning products, should take appropriate protective measures, such as wearing rubber gloves, use detergent laundry; physical contact with chemicals, to be more clean water; room and more windows open for ventilation and so on. When using cleaning products if dizziness, allergies and other adverse reactions, should be timely medical treatment.

Ten bad habits make you a candidate for cancer part 4

Often second-hand smoking.
In addition to the well-known lung cancer, smoking can lead to nasopharyngeal cancer, oral cancer, esophageal cancer, and even bladder cancer, kidney cancer, pancreatic cancer and gastric cancer, described as "a cigarette in hand, the whole body suffers." In addition, studies have shown that the hazards of passive smoking on the body than the hand smoking counterparts. Therefore, the best hands quickly snuffed the cigarette, the farther away from the smoke, the better.
Too luxurious decoration.
In addition to smoking, also contributed to the decoration of the pungent odor of lung cancer culprit. Many building materials contain cancer-causing chemical in the composition, more luxurious decoration, so that the greater the risk of physical injury. For children, decoration pollution are more likely to allow them to suffer from leukemia. Experts suggest buying furniture, decoration, building materials, cheaper plans do not, in general, quality products, the more times the more pungent flavor; decoration must be windows open for ventilation; decoration hanging after at least two or three months before admission.
Family has cancer.
If the previous generation with breast cancer, lung cancer, esophageal cancer, colon cancer, the risk of future cancer is much higher than the average person. In addition, the Shanghai Cooperation Center for Cancer Research that the death of every 100 couples, at least 5 pairs of suffering "husband and wife cancer." This year husband and wife to maintain the same living habits. Therefore, once the self-examination to the two men have unhealthy habits, the couple should be taken seriously, with the correction. People who have family history of cancer to be the best cancer screening on a regular basis, better than others to maintain a healthy lifestyle.

Ten bad habits make you a candidate for cancer part 2

Always hold back stool.
Want to go to stool, can be chosen too busy to get away, or could not find the bathroom, only hard simmering. Two back, and a back line, a long time, it will go wrong. Manure contains hydrogen sulfide, skatole, and other carcinogenic metabolites of cholesterol, accumulated in the intestine for a long time, will be repeatedly absorbed and stimulate the intestinal mucosa. Tianjin Cancer Hospital, a survey has been no time to bowel movement, many young people suffering from colorectal cancer the main reason. Experts suggest that we must seize the day "it means" the most concentrated moment, one morning soon after, one after dinner. It means usually only a few minutes, once missed very difficult to capture. The morning is no time to bowel movement, you can adjust to the more free nights. After dinner walk clockwise massage of the abdomen, then no matter whether they intended to, time to squatting squatting toilet. Stool 3-5 minutes of the general discharge, you should give up, do not stay in the toilet for a long time reading newspapers.
Do not sleep at night.
Many people had to stay up late for work overtime; also fashion, every day, pub, has become nocturnal "party animals." Cancer Research UK Centre for Scientific Research from around the world more than 1,000 30-50 year-old cancer patients, found that 99.3% of people staying up all year round, closed only after midnight. Experts pointed out that the clock will cause disturbance late at night on the one hand, on the other hand, the night light will destroy the formation of human melatonin, which is to protect the human immune system an important part, the lack of it is easy for leukemia, breast cancer, prostate cancer, and so find door. Best not to stay up late more than 12 points. If you work until midnight, it is best to find a room with curtains with shade cloth to sleep in a dark environment helps the body produce melatonin.
Sit down and do not want to move.
Sit on the day to work, go home stuck in the sofa do not want to move ... ... just do not think the dangers of sitting injured cervical spine. German experts pointed out that the number of immune cells with the increase of activity, sedentary human body immune cells decreased greatly increased risk of cancer; Japanese medical scientists found that cancer patients are usually eaten too much and sedentary; U.S. study shows that regular exercise than sedentary people the possibility of colon cancer 40% -50% higher for men suffering from prostate cancer also easy. Experts point out that the work of every 2 hours, 15 minutes must be up activities.

15 early symptoms of cancer, do you know? part 2

Men and women should be noted:
1. Breast lumps. When women find the breast skin redness, lumps, will exceptionally careful. Non-lactating women, nipple retraction, and often out of the liquid, but also a bad signal. For men, if the breast skin wrinkling, shrinkage or asymmetrical nipples, nipple size and shape of changes, breast swelling, lumps appear, are inflammation of the performance of the nipple is breast cancer symptoms.
2. Pain. With increasing age, pain will increase. However, certain parts of the body and inexplicable pain for more than a week, find out the cause as soon as possible, because the reason the pain may be signs of cancer. For example, long-term pain is a symptom of colorectal cancer, chest pain may be caused by lung cancer, bone pain may be symptoms of cancer metastasis.
3. Lymph node changes. Experts point out that no matter which part of the body, especially the axillary lymph nodes or Jingbo appears, must not be taken lightly. If the lymph nodes is increasing steadily, more than 1 month, it is likely that the symptoms of breast cancer or brain cancer.
4. Fever. Fever usually caused by influenza, pneumonia, or inflammation caused by other, however, unexplained fever, it could be a dangerous sign. American Cancer Society, said the spread of cancer to other body organs, usually results in fever. Lymphoma, leukemia and other blood cancer also have a fever. Need to examine include: X-ray chest, CT scan, MRI and so on.
5. Weight inexplicably reduced. You can lose weight without strenuous indeed gratifying, but if neither increase physical activity within one month, was not any reduction of diet, body weight decreased by 10% but somehow, you should consult a doctor immediately. Sharp decline in body weight, anorexia, recurrent diarrhea and constipation are the most common form of lung, stomach, kidney cancer and colorectal cancer symptoms for women may also be hyperthyroidism.
6. Continued abdominal pain and with depression. If persistent pain and abdominal symptoms associated with depression, most likely with pancreatic cancer. Experts found significant relationship between depression and pancreatic cancer. Other symptoms include: jaundice or abnormal stool was gray.
7. Fatigue. In general, the feeling of fatigue, is a sign of cancer have been developed, but for leukemia, colon cancer and gastric cancer, it may be the early onset of fatigue. Cancer fatigue and general fatigue what is the difference? General fatigue rest will disappear, and no matter how off the fatigue of cancer, will find it difficult to improve.
8. Coughing. Unexplained persistent cough if more than 3-4 weeks, you should see a doctor promptly, it may be a sign of lung cancer or throat cancer.
9. Dysphagia. Long-term swallowing difficulties may be laryngeal cancer, esophageal cancer and stomach cancer symptoms, it should be as early as possible chest X-ray or gastroscopy. The so-called dysphagia, generally refers to chest pain when eating, esophageal foreign body sensation, even if some people do not eat, food will feel like a wall of leaves, debris or grain-like material attached, will feel after swallowing the food under the food down slow, or even stay in the esophagus.
10. Skin changes. Mass or the sudden appearance of skin pigmentation, and changes significantly, may be a sign of skin cancer was observed after a few weeks should seek medical care immediately. In addition, both young and old, once a sudden hemorrhage or abnormal skin peeling off, it should see a doctor.
11. Abnormal bleeding. Blood in the stool in addition to hemorrhoids, the symptoms of colorectal cancer is likely to be necessary, should accept the colon cancer screening colonoscopy. In the elderly over the age of 40, in addition to women outside the menstrual period, such as painless hematuria or dysuria should be wary of bladder cancer or kidney cancer. In addition to colorectal cancer than blood in the stool, if tumor growth near the anus may also occur thinning stool, increased frequency and other symptoms, or even cause bowel problems.
12. Oral changes. Smokers should pay special attention to the oral cavity and tongue, white patches appear, which may be a precursor to oral cancer --- leukoplakia.
13. Indigestion. Men (especially older men) and women (excluding pregnancy) for a long time unexplained persistent indigestion may be esophageal cancer, laryngeal cancer, stomach cancer symptoms.
With the progress and development of medicine for cancer treatment has been expanded from a simple surgical treatment to chemotherapy, radiation therapy, biological therapy and combination therapy in many ways, a lot of 5-year survival rate of malignant tumors has increased every year, and the quality of life also significantly improved the prognosis for most patients as healthy people can live a normal life, work and study. But these good results will depend on the treatment of cancer, early detection and standardized treatment.

Winter indoor air pollution when the anti-leukemia

With the advent of winter, both in the office or home interior, large windows and doors are closed, over time, the indoor air becomes polluted, it is easy to bring to the human disease.
With the increasingly serious environmental pollution, environmental exposure and childhood leukemia in the relations of the people's attention. Indoor air is the most frequent contact with people, one of the closest external environment, it is about 70% to 90% of the time is spent indoors, time of exposure to indoor air pollution than outdoor, especially children, in time for indoor activities longer merits of their indoor air quality is more important. Children's Cancer largest proportion of leukemia, the highest fatality rate in recent years, epidemiological studies indicated that the rise of its incidence, prevention and treatment of childhood leukemia is leukemia research priorities and hot spots.
At present, the specific cause of childhood leukemia is not clear. Most of that is the combined effect of multiple factors (individual susceptibility and the external environment) the results. Indoor air pollution on the incidence of leukemia in children may play more important role.
1 smoking
Control of smoking is a public health problem need to be resolved, the harm caused by passive smoking is particularly serious. Many studies confirm that smoking is a main cause of lung cancer, in addition to lung cancer, but also can cause a variety of cancers. According to WHO reports, the tobacco smoke "affirmative carcinogen" not less than 44. Smoking parents can make their own risk of leukemia increased by 50%, and acute myeloid leukemia (AML) adversely affect the prognosis, the survival shortened. Mother heavy smokers (≥ l0 cigarettes / day) can increase the risk of AML children, the highest hazard ratio up to 2.67.
2, benzene and other organic solvents
Benzene is an aromatic organic solvent slightly in industry has a wide range of uses. The major source of indoor benzene pollution is indoor and outdoor air pollution, indoor decoration materials into the release of volatile organic compounds. Once the interior decoration, they may be able to release material from the fitting to the indoor air in the past. If too many people exposed to indoor air pollution such, the human health will be affected by different degrees of damage. Long-term exposure to low concentrations of benzene can lead to chronic benzene poisoning, aplastic anemia, myelodysplastic syndrome or leukemia.
Professional relationship between benzene exposure and adult leukemia study findings have been positive in each of the concentration of 67 mg/m3 of benzene exposure of workers suffering from AML risk 20 times higher than the general population; workers exposed to benzene in acute lymphoblastic leukemia (ALL) incidence higher than other groups. There is currently a lack of childhood leukemia and direct relationship between benzene exposure, but the concentration of benzene in indoor air may be growing one of the causes of childhood leukemia. British researchers found that living in the surrounding traffic arteries or the gas station within 100 m of children exposed to benzene and other hydrocarbons concentrations higher than children in other places, the risk of leukemia in children than in other regions increased slightly, AML, ALL, CLL and family are significantly correlated with the number of cars, inferred exposure to benzene in gasoline may be the reason. Childhood leukemia and residential on the nearby factories, or 2 main types of industrial air emissions - oil volatiles and smoke emissions from boilers or internal combustion engine with an increased risk. Air pollution is serious in some areas, large number of leukemia in children.
The survey found that 90% of the families of leukemia patients 6 months to 1 year has been renovated and most have used the luxury and fashion-type stone decoration materials. If the mother before pregnancy and pregnancy exposure to solvents, paints, thinners, cosmetic agent, cosmetic agent contact with the father before marriage will increase the risk of childhood ALL, and the time effect relationship. Regular contact with children (more than 4 times / month) prevalence of organic solvents will lead to increased risk of ALL, and found that mothers of children born in the year before living in the paint brush over the room, the child was born troubles increased risk of ALL, so ALL children increase the risk of indoor activities and children with certain birth living room paint exposures.
Three chemicals
Household chemicals that are used to family life and living environment of the chemical products. Family of chemicals widely used to infiltrate people's clothing, food, housing, among, across all aspects of life, so has the use of dispersing agents and household chemicals, high demand, people exposed to a wide range (including all ages) and exposure for a long time and so on. Use a variety of household chemicals because of their purpose, manner, to the scope of the human body through different channels and pose a health hazard. Children exposed to household chemicals from region to region and family environment in which a great relationship, in which pesticides and dyes closer relationship with childhood leukemia.
A number of studies show that pesticides and leukemia related. Occupational exposure to pesticides and family, especially children with leukemia AML occurs highly correlated. Father has a history of exposure to increased susceptibility of children, children exposed to risk of pesticides than adults. Type of use of pesticides within the family the more the frequency the greater the risk the greater the likelihood ALL.
