Melanoma may be related to air pollution. How to prevent melanoma in daily life

Melanoma is one of the most common skin tumors. If it is not treated in time, it is likely to cause skin cancer. This is one of the reasons why melanoma is given special attention in medicine. So, what are the factors that cause melanoma, and how should we deal with melanoma in our daily lives?

Melanoma may be associated with air pollution

1. Race factors. The cause of melanoma may be related to race. Experts point out that the incidence of melanoma in white people is higher than that in people of color. For example, the annual incidence rate of white people in the United States is as high as 42/100,000, while that of black people is only 0.8/100,000.

2. Immunodeficiency. Immunodeficiency is also one of the causes of melanoma. With the increase of age, the immune function of the human body gradually declines. Therefore, the incidence of melanoma in the elderly is very high clinically.

3. Abuse of estrogen drugs. The occurrence of melanoma may also be related to the abuse of estrogen drugs. Studies have found that there are estrogen receptors in the cells of malignant melanoma, and people suspect that excessive estrogen will stimulate the occurrence of melanoma.

4. Air pollution. Experts say that the occurrence of melanoma may also be related to air pollution. The large-scale emission of harmful substances destroys the ozone layer, resulting in insufficient ultraviolet filtration. Harmful ultraviolet rays and harmful substances in the air work together to act on human skin, causing abnormal expression of melanocytes, which can easily cause melanoma.

Melanoma prevention can start with diet

1. Prevention of melanoma For pigmented nevi that occur in areas prone to friction, biopsy should be performed for pathological examination. For example, if a child has a large hairy nevus on the waist, it is often rubbed and squeezed by the belt, so it should be completely removed as soon as possible. If it is difficult to remove all of it at once, the main part can be removed as much as possible in the middle of the large hairy nevus before it becomes malignant, and the two sides can be sutured. After the surrounding skin is loosened, the remaining part can be removed until the nevus is completely removed to prevent malignant transformation. Each specimen removed must be sent for pathological examination. If there is malignant transformation, it should be completely removed and skin grafting should be performed. This is the prevention measure for melanoma.

2. Do not use corrosive drugs or complete freezing to stimulate moles. If the moles cannot be frozen off once and are repeatedly frozen several times, it is dangerous, because moles often become malignant due to traumatic stimulation. It is reported that some people have become malignant due to incomplete freezing. About 30% to 50% of malignant melanomas are related to external stimulation. If it is necessary for beauty, it is safer and more reliable to remove the mole at one time. Cryotherapy combined with excision should be completed in one time. Do not remove in multiple times. The excised specimens should be sent for pathological examination. This is also one of the preventive measures for melanoma.

3. Melanoma patients should eat more fresh vegetables and fruits

Fresh fruits and vegetables contain a lot of vitamin A, vitamin C, vitamin E, etc. Recent studies have found that they have antioxidant effects, can remove free radicals, block the synthesis of carcinogenic nitrosamines, inhibit the degeneration of squamous epithelial cells and the occurrence of cancer cells, and also have the effects of enhancing the body's immune function and promoting ulcer healing. When eating green leafy vegetables, you should eat them as soon as you buy them, and don't leave them for too long, preferably overnight to avoid the loss of vitamins and other nutrients caused by storage.

4. Eat less fat

Although fat is the main source of calories for the human body, it should not be consumed in excess. A long-term high-fat diet for melanoma patients can easily lead to melanoma, colorectal cancer, and breast cancer. Cancer patients often experience nausea, vomiting, aversion to greasy food, and poor digestion during treatment or disease progression, so they should adopt a low-fat diet.

5. Protein intake should not be excessive and the diet should be diversified

Because cancer patients often experience digestive tract reactions during radiotherapy and chemotherapy, which weakens digestive function, or tumors increase body consumption and cause malnutrition or even cachexia, many people blindly adopt high-protein diets. Little do they know that high-protein diets will increase the burden on the gastrointestinal tract, weaken gastrointestinal digestion and absorption functions, and are not conducive to tumor treatment. Many experiments have shown that high-protein diets are positively correlated with the incidence of ovarian cancer and prostate cancer. This is one of the dietary precautions for melanoma patients.
