Melanoma on the foot

Many people cannot distinguish between melanoma and moles. How to distinguish the two? There is a big difference between them, and the symptoms are also different. Some people wonder, it is unlikely to have melanoma on the feet. Melanoma can grow in many places, and the feet and arms are more common. Don't be careless if there are abnormalities in the skin, and check them in time. The following is a detailed introduction to moles and melanoma.

Malignant melanoma is a very serious skin cancer because its cancer cells can metastasize to any part of the body through the lymph nodes and blood. The causes of melanoma are complex and may be related to dysmorphic nevi, endocrine factors, genetic factors, immunosuppression, and immune deficiency. The most dangerous factor for mole malignancy is ultraviolet radiation. Westerners like to bask in the sun, like sunbathing, and even sunbathe naked, so they have a high incidence of skin cancer and melanoma. What kind of moles are likely to deteriorate into melanoma? Moles in areas that are often subject to friction are most likely to become malignant. Moles on parts of the body that are often subject to friction are most likely to become malignant, such as the waist, where belts often tighten. And the neck, because the collar often causes friction. The palms and soles of the feet are also the places that are usually subject to more friction and greater forces.

The difference between melanoma and mole 1. The edge of the mole is smooth and clearly demarcated from the surrounding skin. The edges of malignant melanoma are irregular, serrated, and rough with scaly or flaky desquamation, sometimes with exudate or bleeding, and the lesions are higher than the skin. 2. The diameter of malignant melanoma is greater than 5 mm. The diameter of a mole is usually less than 5 mm. 3. The two halves of malignant melanoma are asymmetrical. The opposite is true for moles. 4. Malignant melanoma will mix the color of ordinary moles with blue-black, pink and white. White indicates that the tumor has spontaneous degeneration. Nodular melanomas are always bluish black or gray. Pay attention when a mole shows this kind of phenomenon! Pay special attention if the mole becomes itchy or painful when pressed. If the condition continues to progress, it is likely to develop into ulcerative lesions, which may lead to a more stinging or burning sensation. If satellite nodules appear around the disease or there is regional lymph node enlargement, it means that the disease has progressed to the late stage.

How to prevent moles from deteriorating into melanoma 1. For moles that grow in areas prone to friction, it is best to go to the hospital for regular check-ups to detect lesions in a timely manner. 2. Don’t remove moles casually. 3. Eating more anti-cancer foods can prevent the occurrence of cancer. Therefore, having black moles on your body is not necessarily a very common thing. If they grow in places that are prone to friction, you should pay more attention to them. If there are any abnormalities, you should seek medical attention in time to nip the cancer in the bud as early as possible.
