1, exercise and coffee to prevent skin cancer

As we all know, regular exercise has many benefits, and drinking coffee in moderation is also good for your health. A new study announced at the annual meeting of the American Association for Cancer Research in Chicago found that drinking coffee before and after exercise can also prevent cancer, because caffeine combined with exercise can help reduce the risk of skin cancer.

Drinking coffee regularly can reduce the risk of head and neck cancer.

A recent study in the United States shows that drinking coffee regularly can reduce the risk of head and neck cancer.

Head and neck cancer includes oral cancer, nasal cancer, nasal sinus cancer, salivary gland adenocarcinoma and lymphoma. Researchers at the University of Utah in the United States reported in the latest issue of Cancer Epidemiology, Biomarkers and Prevention that after analyzing nine research data provided by the International Federation of Epidemiology of Head and Neck Cancer, they found that people who drink coffee regularly have lower risk of oral cancer and throat cancer than those who don't drink coffee regularly. If you drink more than 4 cups of coffee every day, this effect will be more obvious.

The researchers explained that antioxidants and other chemicals contained in coffee may be one of the reasons for its anticancer effect, but further research is needed to understand its specific anticancer mechanism. Previous studies in the United States and Britain have shown that drinking coffee regularly can reduce the risk of prostate cancer, glioma and brain tumor.

3. Drinking caffeinated coffee regularly can reduce the risk of basal cell carcinoma.

A recent study by researchers at Harvard Medical School in the United States shows that drinking caffeinated coffee often helps to reduce the risk of common skin cancer-basal cell carcinoma. Related research reports were published in this week's American magazine Cancer Research.

Basal cell carcinoma is the most common malignant tumor of the skin, which usually occurs on the face. In foreign countries, more than half of skin cancer patients suffer from basal cell carcinoma. According to the National Cancer Institute, about one million people in the United States receive treatment for basal cell carcinoma every year. The researchers analyzed the data of 1 12000 people who participated in the Health Career Tracking Study and the Nurses' Health Study for more than 20 years, and found that women who drank more than three cups of caffeinated coffee a day had a lower risk of basal cell cancer than women who drank less than one cup a month by 2 1%. For similar men, the risk is reduced 10%.

They also found that regular intake of caffeine-containing tea or chocolate can also play the same role, but it can not reduce the risk of squamous cell carcinoma, melanoma and other skin cancers; There is no correlation between drinking decaffeinated coffee and the risk of basal cell carcinoma.

The researchers said that previous mouse experiments showed that caffeine can inhibit tumor growth, and this study showed that caffeine may also play a similar role in the human body.

4. Coffee may reduce the risk of liver cancer in China.

4. Coffee may reduce the risk of liver cancer in China.

According to Xinhua News Agency, a study on Chinese in Singapore shows that drinking three or more cups of coffee a day may reduce the risk of liver cancer by 44%.

A research team from the Department of Epidemiology and Public Health of the National University of Singapore published a paper in the American journal Cancer Causes and Control, inferring that coffee beans contain two lipids, namely caffeic alcohol and caffeic alcohol, which have protective effects on human liver.

The research started in 1993, and the subjects were more than 63,000 men and women aged 45 to 74 in China. Singapore's Straits Times 16 reported that it is generally believed that compared with other ethnic groups, Chinese people have a relatively high risk of liver cancer.

Coffee helps reduce the risk of liver cancer. In 2005, Japanese researchers reached a conclusion by following up 90,000 Japanese people for as long as 10 years. This may be the first time that Singaporean researchers have explored the effectiveness of coffee for China people.

Drinking coffee regularly can reduce the risk of breast cancer in women.

Breast cancer is one of the most common malignant tumors in women. According to statistics, the incidence of breast cancer accounts for 7- 10% of all kinds of malignant tumors in the whole body. Studies have shown that drinking coffee helps protect women from the threat of breast cancer, which usually means that chemotherapy is the only option.

According to foreign media reports, in this study conducted by Karolinska Research Center in Stockholm, Sweden, scientists found that coffee drinkers are much less likely to develop breast cancer. They analyzed the relevant cases and data of 6000 menopausal women before, and found that women who drink more than 5 cups of coffee a day have a reduced risk of breast cancer by about 57% compared with women who usually drink less than 1 cup a day. Through the follow-up research report, scientists concluded that drinking more coffee is closely related to significantly reducing the incidence of breast cancer in postmenopausal women.

Previous studies have shown that coffee can also reduce the risk of other types of cancer, including cancer related to prostate cancer and liver cancer. However, there are still huge differences in this view, and even studies have shown that coffee can promote the occurrence of cancer. For example, some studies show that coffee may lead to cell proliferation or prevent its repair.

Experts in karolinska institutet, Sweden, said they suspected that the compounds contained in coffee may affect different types of breast cancer in different ways, but the specific relationship needs further study. In addition, a recent study in the United States found that some compounds contained in parsley and some fruits and nuts can prevent the proliferation of breast cancer cells.
