Xu Ting once revealed in Weibo, "For 25 years, I never seem to live for myself ... For five years, I stayed up late to shoot movies, pay my parents' debts and buy a house ..."

Yu Juan once wrote in her blog, "Recalling 10, I basically didn't sleep before 12. For study, postgraduate study, chatting, discos, karaoke and so on. When I was terrible, I didn't sleep all night. Generally, I fell asleep at around 1 o at the earliest. "

Staying up late for a long time will disturb the biological clock of the human body and lead to the damage of tumor suppressor genes. A study published in Cell Metabolism by Koch Institute of Massachusetts Institute of Technology found that staying up late increases the risk of cancer. Staying up late for a long time will cause dysfunction of neuroendocrine system, imbalance of estrogen and progesterone, easy to cause endocrine disorders, decreased immunity, and easy to appear cancerous masses.

2. Stress

Xu Ting once wrote in Weibo: "I'm so tired, I'm still filming in the ice water in winter, and I can't breathe. I felt a little relieved when I learned that I had cancer. I think I'm going to be free. " Being in a high-pressure environment for a long time is very harmful to your health. Researchers at Monash University in Australia have recently found that excessive stress may not only lead to cancer, but also accelerate the spread of cancer cells.

Step 3 overwork

A study by the University of Washington in the United States also pointed out that overwork can easily induce cancer. Many cancer patients look back two or three years before the onset, usually with great physical and mental stress. The reason why fatigue can induce cancer is that people's body is in a state of overwork and mental stress for many years, and their immune function is reduced, which makes the body's ability to repair DNA decline, and fatigue easily leads to malignant changes. Lymphoma is the most easily exhausted, and overwork leads to blood overdraft. Some compensatory mechanisms need the automatic adjustment and supplement of lymphatic system, which leads to infinite proliferation of lymph.

Step 4 drink too much

The more you drink, the greater the risk of cancer, and the harm of alcohol to the liver is gradually accumulating. From alcoholic fatty liver to alcoholic hepatitis to alcoholic cirrhosis, it takes only four steps to finally lead to liver cancer. It can be said that if you drink too much, every time you drink more, you will be one step closer to liver cancer.

Most alcohol is metabolized in the liver, and only a small part is excreted through the kidneys and lungs. After drinking a lot of alcohol, a large amount of acetaldehyde will accumulate in the human body, which will have toxic effects on many tissues and organs, such as DNA damage and carcinogenesis.

Step 5 clean

He Yumin, a famous oncologist, found that there are many cleanliness addicts among clinical cancer patients, and a male anchor who pursues perfection everywhere and pays great attention to health care is a typical case. His desk is always spotless, and there are several layers of small things on the stool. He could tell at a glance who had used his stool, but he ended up with cancer.

Some research results show that cancer prefers neat addicts. And its deep mechanism may be the same as that of perfectionists. Cleanliness addicts are often in a high-pressure state of self-setting, pursuing cleanliness and spotless, so that some studies believe that cleanliness addicts (including perfectionists) often have weak self-repair ability. Once it becomes cancerous, it is difficult to repair itself, and the probability of developing cancer increases.

Step 6 get angry

Anger and depression can lead to emotional disorders. In the view of Chinese medicine, emotional disorder can easily lead to disharmony between liver and gallbladder and depression of liver. If the disharmony between liver and gallbladder is not conducive to regulating qi, then our body will have various problems, many a mickle makes a mickle, and may even lead to cancer.

Luo Dalun, a Chinese doctor, mentioned that some friends from other places asked me to go to the hospital to see an old Chinese doctor for breast cancer. The number of the old Chinese doctor was hung up a few months later. I didn't expect so many breast cancer patients now. In fact, this disease is directly related to the discomfort of liver qi, and the aggravation of this disease has a lot to do with our stress. The pressure of family and work will lead to emotional instability of women and eventually lead to illness.

7. Obesity

According to statistics from Cancer Research UK, compared with women with healthy weight, the probability of obese women suffering from various cancers has increased by nearly 40%.

At present, it has been confirmed that obesity-related cancers include: breast cancer (postmenopausal), intestinal cancer, pancreatic cancer, esophageal cancer, uterine (endometrial) cancer, renal cancer and gallbladder cancer. The research team calculated that the risk of obese women suffering from one of the seven cancers is nearly 465,438+0% higher than that of healthy weight women.

8. Smoking

Smoking has always been the first killer of lung cancer! Tobacco contains hundreds of chemicals, more than 60 of which are related to cancer. Suppose that the probability of ordinary people suffering from lung cancer is 1, and the probability of heavy smokers suffering from cancer is 17 times that of ordinary non-smokers.

In the United States, nearly 50% of cancer patients die from smoking. Researchers of the American Cancer Society said in a research paper published in the international journal Journal of Internal Medicine of the American Medical Association that in 20 1 1 year, 346,000 adults aged 35 and over died of 12 cancers, of which 48.5% of individual cancer deaths could be attributed to smoking.
