Symptoms of early melanoma
summary
Melanoma is a malignant tumor originated from melanocytes in pigmented areas of skin, mucous membrane, eye and central nervous system. So what are the early symptoms of melanoma? Melanoma is a common skin tumor caused by excessive proliferation of abnormal melanocytes, which is highly malignant and accounts for a large part of the death cases of skin tumors. What's the early symptom of melanoma? Let's talk about it.
Symptoms of early melanoma
First: the surface of patients with melanoma is not smooth, often rough and accompanied by scaly flake desquamation, sometimes bleeding, exudation, can be higher than the skin. This is the early symptom of melanoma.
Second: melanoma patients will feel abnormal, local often itching, burning or tenderness. When the above changes occur, it strongly suggests that there is a suspicion of malignant melanoma. It can be said that once there is any change in the skin nevus, excision and biopsy should be performed to remove the malignant melanoma. The early symptoms of these melanoma are more common.
Third: the early symptoms of melanoma and the edge is often uneven, serrated change, for melanoma tumor to spread around expansion or spontaneous degeneration.
matters needing attention
1. Biopsy should be taken for nevus that occurs in the easily rubbed area. If children's big hair nevus in the waist, often by the friction and compression of the belt, should be completely removed as soon as possible. If it is difficult to remove all the moles at one time, the main part can be removed as far as possible in the middle of the nevus before malignant transformation, and the two sides can be sutured. After the surrounding skin is marathon, the rest can be removed until the nevus is completely removed, so as to prevent malignant transformation. Each resected specimen must be sent for pathological examination. If there is malignant transformation, it should be completely removed and skin grafting should be performed. 2. It is not suitable to use corrosive drugs or thorough freezing to stimulate nevus. Once frozen and repeated several times, is dangerous, because nevus often due to traumatic stimulation and malignant transformation. According to reports, it was because of a frozen incomplete and malignant transformation. About 30% - 50% of malignant melanoma is related to external stimulation. If because of the need of beauty, the nevus should be removed at one time, which is relatively safe and reliable. Cryosurgery combined with resection should be done at one time. The resected specimens should be sent for pathological examination.
