Regular coffee drinking helps reduce cancer risk

With the increase in the incidence and the number of cases, cancer, which is regarded as an "incurable disease", has been paid more and more attention by the medical community, but unfortunately, there are few drugs and treatments that can completely cure cancer so far. can only reduce the spread of cancer cells to a certain extent. At the same time, more and more attention and research have been paid to the ways to reduce the risk of cancer through a variety of dietotherapy, exercise and health drugs.

Traditional Chinese medicine pays attention to prevention, and drug therapy is not as good as dietotherapy, so those foods with anti-cancer effects are becoming more and more popular, including sweet potatoes, garlic, carrots, figs, soybeans, green tea and so on. Coffee is also a very good anti-cancer food, and appropriate drinking, has a very good preventive effect on many kinds of cancer, let's learn about it one by one!

1. Exercise plus 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 also has anti-cancer effects because caffeine combined with exercise can reduce the risk of skin cancer.

2. Coffee helps prevent head and neck cancer

Japanese researchers announced at the meeting of the Japan Cancer Society held in Osaka on the 22nd that people who drink a lot of coffee will have a lower risk of head and neck cancer in the mouth and pharynx.

This is Aichi Prefecture Cancer Center Research Institute Oase Gong and others in the epidemiological investigation found. The team surveyed the habits of 961 patients with head and neck cancer, esophageal cancer and 2883 healthy people and found that there was no significant difference in the risk of head and neck cancer between those who drank less than one cup of coffee a day and those who drank one cup of coffee a day. However, if you drink more than two cups of coffee a day, the risk of head and neck cancer will be reduced. People who drank more than three cups of coffee a day had a nearly half lower risk of cancer than those who drank less than one cup of coffee a day.

The team also found that people who drank more coffee had a lower risk of head and neck cancer among smokers and drinkers. However, drinking coffee has no preventive effect on esophageal cancer.

"after the substance in the cell is oxidized, DNA (deoxyribonucleic acid) is damaged, which can cause cancer," Oase said. Perhaps because coffee has the effect of antioxidation and oxidation is neutralized, it prevents head and neck cancer. "

According to previous epidemiological investigations, coffee drinkers are also less likely to suffer from colorectal cancer and liver cancer.

3. Drinking caffeinated coffee regularly may reduce the risk of basal cell cancer.

Drinking coffee with caffeine style=color:blue > caffeine can help reduce the risk of basal cell cancer, a common skin cancer, according to a study completed by researchers at Harvard Medical School. The study was published this week in the American Journal of Cancer Research.

Basal cell carcinoma (BCC) is the most common skin malignant tumor, which often occurs in 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 are treated for basal cell cancer each year. The researchers analyzed data from 112000 people who took part in the Health Occupational follow-up study and the Nurses' Health study over a period of more than 20 years. Women who drank more than three cups of caffeinated coffee a day had a 21 per cent lower risk of basal cell cancer than those who drank less than one cup a month; for similar men, the risk was reduced by 10 per cent.

They also found that regular consumption of caffeinated tea or chocolate had the same effect, but did not reduce the risk of squamous cell cancer, melanoma and other skin cancers; there was no association between drinking non-caffeinated coffee and the risk of basal cell cancer.

Previous mouse experiments have shown that caffeine can inhibit tumor growth, and this study suggests that caffeine may have a similar effect in humans, the researchers said.

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

Drinking coffee regularly can reduce the risk of head and neck cancer, according to a new study in the United States.

Head and neck cancer includes oral cancer, nasal cancer, paranasal sinus cancer, salivary adenocarcinoma and lymphatic carcinoma. Researchers at the University of Utah reported in the latest issue of Cancer Epidemiology, Biomarkers and Prevention that they analyzed data from nine studies provided by the International Federation of head and neck Cancer Epidemiology. people who drink coffee regularly are 39 percent less likely to develop oral and throat cancer than those who do not drink coffee regularly. If you drink more than 4 cups of coffee a day, the effect will be more obvious.

The researchers explained that many chemicals such as antioxidants in coffee may be one of the reasons for its anti-cancer effect, but more in-depth research is needed to understand its specific anti-cancer mechanism. Previous studies in the United States and Britain have shown that drinking coffee can reduce the risk of prostate cancer, gliomas and brain tumors.

5. Coffee may reduce the risk of liver cancer among Chinese.

Drinking three or more cups of coffee a day may reduce the risk of liver cancer by 44 percent, according to a study of ethnic Chinese in Singapore, Xinhua reported.

A research team from the Department of Epidemiology and Public Health of the National University of Singapore published a paper in the American Journal of Cancer inducement and Control, concluding that coffee beans contain two lipids, caffeine and caffeinol, which have a protective effect on the human liver.

The study, which began in 1993, involved more than 63000 Chinese men and women aged 45 to 74. It is generally believed that compared with other ethnic groups, ethnic Chinese have a relatively high risk of developing liver cancer, Singapore's Straits Times reported on the 16th.

Coffee helps reduce the risk of liver cancer, according to a 10-year follow-up of 90,000 Japanese by Japanese researchers in 2005. It may be the first time for Singaporean researchers to explore the effectiveness of coffee for ethnic Chinese.

6. Drinking coffee regularly reduces the risk of breast cancer in women.

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

According to foreign media reports, in the study conducted by the Karolinska Research Center in Stockholm, Sweden, scientists found that people who drank coffee were much less likely to develop breast cancer. They analyzed cases and data from 6000 previous menopausal women and found that those who drank more than five cups of coffee a day had a 57 per cent lower risk of breast cancer than those who typically drank less than one cup a day. By tracking the study, the scientists concluded that higher coffee intake was closely related to a significant reduction in 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 those associated with the prostate and liver. However, there are still great differences in this view, and some studies have even shown that coffee can promote the development of cancer, for example, studies have shown that coffee may cause cell proliferation or prevent its repair.

Experts at the Karolinska Institute in Sweden say they suspect that the compounds that coffee may contain may affect different types of breast cancer in different ways, but the relationship needs further research. In addition, a recent study in the United States found that certain compounds in parsley and some fruit nuts can prevent the proliferation of breast cancer cells. (to be continued)
