Symptoms of skin melanoma

Long-term exposure to the sun may cause melanin to appear on the skin. So when you go out, you must take sun protection measures. Some moles are not noticeable, but if they are large, they may be melanoma. However, this kind of toxin needs to be checked in the hospital. If it can be removed, it is better to remove it. Generally, melanoma does not cause any discomfort, itching or pain. So it is easy to be overlooked, so it is better to remove it.

Don't miss early warning signs

Almost 95% of patients discovered abnormalities one year before the mole showed obvious changes. But they either don't take it seriously and ignore it, or even mistakenly believe that as long as it doesn't hurt or affect their lives, they can ignore it. Don’t you know that malignant melanoma is painless and does not affect your life in the early stages? There are even more wrong methods such as cutting with a knife, strangling with a rope, or even sprinkling salt or garlic on it, which actually accelerate the metastasis of primary melanoma.

When you discover high-risk signs of early melanoma, or have doubts about your own pigmented moles, do not be careless, and do not scratch or scrape them. You must see an experienced specialist in time. If a specialist believes that there is a possibility of melanoma, he or she will usually recommend a standardized complete excision of the nevus and send it for pathological examination. The results of the pathological diagnosis will clarify whether it is melanoma.

Sun exposure causes melanoma

Melanoma is the tumor with the fastest growing incidence among all malignant tumors. It is a malignant tumor of the skin caused by abnormal excessive proliferation of melanocytes. It is highly malignant, prone to recurrence and metastasis, and has a very poor prognosis.

The cause of the disease is still unclear. In Western countries, the incidence rate among Caucasians is much higher than that among people of color, and the main sites of occurrence are the head, face, trunk, and skin. In Asia, more than half of melanomas occur mainly on the hands, feet, limbs, skin, and subungual areas. The currently known causes are mainly excessive ultraviolet radiation and genetic mutations caused by various pollutions. High-risk factors for melanoma include: photosensitive skin that easily freckles; sensitive skin that easily freckles after sun exposure; long-term exposure to the sun; a large number of ordinary moles or dysplastic moles; personal or family history of melanoma.
