How to effectively prevent the occurrence of lung cancer from two perspectives

Lung cancer is a respiratory disease. After years of clinical summary, it has been found that the occurrence of this disease is inseparable from smoking, so the incidence rate in men is much higher than that in women. In addition to smoking, there are other reasons that lead to the occurrence of lung cancer, such as lung cancer caused by industrial waste or lung cancer caused by chemicals. The following experts will explain in detail how to prevent the occurrence of lung cancer from two aspects: diet and chemistry.

Chemoprevention of lung cancer aims to prevent and control lung cancer by intervening in precancerous lesions through the use of drugs, food or nutrients, preventing the occurrence of lung cancer and reversing the differentiation of tumor cells.

Studies have confirmed that eating more green leafy vegetables and tomatoes has a significant protective effect on preventing lung cancer. Researchers have observed that lutein, lycopene, indole and other vegetable ingredients in vegetables have anti-cancer effects on the human body. Ziegler et al. found that cruciferous vegetables (such as rapeseed, cauliflower, cabbage, Chinese cabbage, kale, broccoli, turnip, etc.) have a very prominent protective effect on lung cancer. In their study on lung cancer in Yunnan Tin Miners, the American Cancer Institute and the Institute of Oncology of the Chinese Academy of Medical Sciences found the same results as above, and also found that onions and garlic have a protective effect on lung cancer, and their active ingredients may be carotenoids and their complexes. In the study of the mine, it was found that eating more tofu and eating a moderate amount of meat and eggs also have a protective effect.

Vitamin A can maintain the integrity of cell membranes, maintain normal metabolism of epithelial tissues, block the process of cell carcinogenesis, accelerate the repair of nuclear DNA, and regulate gene expression. Graham found in a study of multi-ethnic populations in Hawaii that people who took less than 25,000 international units of vitamin A per month had a higher risk of developing squamous cell lung cancer than those who took more than 150,000 international units per month. Vitamin A derivatives, carotene, and carotenoids have attracted more attention in preventing lung cancer. Hunan Cancer Hospital reported in 1989 that two mines in Hunan used domestic vitamin A ester (RI) and vitamin A (derivatives of vitamin A) to treat moderate or severe atypical hyperplasia in sputum cells in 1984. After treatment, the general condition improved, and the immunoglobulins IgA and IgM in the blood increased. The incidence of lung cancer in the treatment group was 1 to 4 compared with the control group, and the average level of proliferating cells decreased, indicating that this product has a certain effect in chemical prevention. ?-Carotene is widely present in vegetables and fruits. Epidemiological studies have shown that the ?-carotene content in diet and plasma is negatively correlated with the incidence of lung cancer. Some animal experiments have also observed that ?-carotene can inhibit carcinogenesis. However, two studies on ?-carotene prevention of lung cancer funded by the US NCI have shown that it will increase the incidence of lung cancer in smokers. Therefore, it is not recommended to supplement excessive ?-carotene to prevent lung cancer.

The above experts explained how to prevent lung cancer from two perspectives, and also gave some foods that can prevent lung cancer, such as tomatoes. If you suffer from this disease, you can combine clinical treatment with diet therapy under the guidance of experts to promote improvement of the disease, increase the patient's survival rate and reduce the burden on the family.
