Why are cancer patients often middle-aged? With the increase of age, human organs begin to decline, and the general organs decline around the age of 40. If you don't pay attention to maintenance, the disease will take advantage of it. The pace of modern life is too fast and the environmental pollution is very serious. It is difficult for middle-aged and elderly people whose physique tends to decline to resist diseases. Do you think so?

As for how to prevent it? 1, often eat nuts. A study by Harvard University found that eating three Brazil nuts a day can reduce the incidence of advanced prostate cancer by 48%. How to prevent cancer? Eating nuts regularly can supplement selenium, a key trace element beneficial to human health. Sweat a little every day. A study in university of vermont found that the incidence of lung cancer and colorectal cancer decreased by 68% and 38% respectively. How to prevent cancer? Cancer patients who exercise regularly have more obvious improvement in their condition. The reason is that aerobic exercise and resistance training help to control inflammation and hormone levels and strengthen the immune system against cancer cells.

3. Avoid frying food. How to prevent cancer?

The reason is that high temperature will produce carcinogenic compounds in edible oil. 4. Eat more blueberries. The latest research at Rutgers University found that blueberries are rich in pterostilbene, which can greatly reduce the risk of intestinal precancerous lesions. How to prevent cancer? The continuous development of intestinal precancerous lesions can easily lead to colon cancer. Experts suggest that eating a cup and a half of blueberries (about168g) every day can achieve the anti-cancer effect.

Cancer screening. Many studies have found that colorectal cancer, prostate cancer, testicular cancer, skin cancer and lung cancer can all be found through early screening. How to prevent cancer? Screening for colon cancer in people over 50 years old can reduce the mortality rate of this disease by 60%. Therefore, early screening is one of the key measures to prevent cancer. How to prevent cancer? A new study by the University of Wisconsin found that the cancer mortality rate of patients with severe sleep apnea is nearly five times higher than that of patients with good sleep. The reason is that sleep apnea will lead to the decrease of blood oxygen, which will make small tumors grow new blood vessels, thus accelerating the development of tumors.
