How to prevent “contagious” cancer

Some cancers are “contagious”, not because they are infectious, but because the root cause of these cancers is infectious diseases. Such as cervical cancer and its precancerous lesions have been confirmed to be human papillomavirus (HPV) infection. In addition, Helicobacter pylori and hepatitis virus are important causes of gastric cancer and liver cancer, respectively. Professor Qiao Youlin, director of the Epidemiology Department of the Institute of Oncology, Chinese Academy of Medical Sciences, explained that the three viruses or bacteria that cause precancerous lesions are all infectious, so attention must be paid to prevention.

Cervical cancer prevention: regular screening after age 30

The bane of cervical cancer and its precancerous lesions has been confirmed to be human papillomavirus (HPV) infection. Human papillomavirus is mainly transmitted through sexual contact. Therefore, condom use, restricting the number of partners, delaying the first sexual life and the first childbearing age can help prevent it. Wei Lihui, director of the obstetrics and gynecology department of Peking University People’s Hospital, called for “a woman to regularly screen her cervix after 30 years of age.” Experience from developed countries has shown that cervical screening can significantly reduce cervical cancer mortality by 50%.

Diet prevention: β-carotene supplementation

Beta-carotene is converted into vitamin A in the body, which helps protect the immune system from free radical attacks and has a significant immune-boosting effect. According to scientists’ observations, β-carotene in the blood of patients with cervical cancer is lower than that in the control group, and low β-carotene intake is a risk factor for cervical cancer. Animal foods containing more vitamin A are: animal livers and eggs. Plant foods rich in β-carotene are: spinach, rape, amaranth, lettuce leaves, and pumpkin.

Gastric Cancer Prevention: Meal Split

Helicobacter pylori can cause gastritis and peptic ulcers, which can lead to gastric cancer. Helicobacter pylori may be transmitted through the digestive tract. It is recommended to use public chopsticks and spoons when dining together.

Diet prevention: eat more antioxidant foods

Tomato contains lycopene and carotene, which are antioxidants, especially lycopene, which can neutralize free radicals in the body and is a good food for preventing gastric cancer.

Mushrooms This kind of food includes winter mushrooms, shiitake mushrooms, enoki mushrooms, etc. and fungus. Scientists have found that they all contain anti-cancer substances and have anti-cancer effects.

Garlic is a recognized anti-cancer food and has obvious anti-cancer effects. An epidemiological investigation shows that the incidence of gastric cancer is very low in people who eat raw garlic, because garlic can significantly reduce the nitrite content in the stomach, which can prevent gastric cancer.

Onions Onions contain a natural anticancer substance. Studies show that people who regularly eat onions have a 25% lower incidence of gastric cancer than people who eat less or no onions.

Preventing liver cancer: vaccination

Viral hepatitis is an important cause of liver cancer, so vaccinations against hepatitis B can play an indirect role in preventing liver cancer. In addition, you should stop smoking and limit alcohol, low-salt, low-oil diet, and maintain a good mood.

Diet prevention: eat three more bamboo shoots

Bamboo shoots have a laxative effect. Escherichia coli in the intestinal tract can turn bamboo shoots cellulose into vitamins needed by the human body.

Lettuce is rich in calcium, carotene and vitamin C. It also helps HBV and HCV carriers and patients with chronic liver disease to increase appetite. People with liver cirrhosis and anemia often eat lettuce, which can promote the secretion of organic acids and enzymes, increase iron absorption, help platelet rise and recovery, and prevent disease deterioration.

Asparagus contains nucleic acids, folic acid, glutathione, and choline, which can effectively inhibit the growth of cancer cells.
