What are the early symptoms of melanoma?

Melanoma is a common skin disease. It is more common in middle-aged and elderly people and has a wide range of incidence. It is necessary to understand the early symptoms of melanoma, which is very helpful for the treatment of melanoma. So what are the early symptoms of melanoma ? The following is a detailed answer from relevant experts.

Initially, melanin is deposited on normal skin, or pigmentation of moles increases, and the black color deepens. Then the lesions continue to expand, the hardness increases, and there is an itchy and painful feeling. Some melanoma lesions are raised, plaque-shaped, and nodular, and some are mushroom-shaped or cauliflower-shaped. When they grow into the subcutaneous tissue, they appear as subcutaneous nodules or lumps. If they spread to the surrounding areas, star-shaped black spots or small nodules appear. Common manifestations are regional lymph node metastasis of melanoma, and even regional lymph node enlargement leads to medical treatment. These are all early symptoms of melanoma. In the late stage, the blood flow is transferred to the lungs, liver, bones, and brain.

Most malignant melanomas originate from melanocytes in normal skin. Malignant melanoma is rare in children, but can originate from very large pigmented moles that are present at birth. Halo nevi usually disappear on their own but in rare cases they can become melanomas. Although melanoma is more likely to occur during pregnancy, pregnancy does not increase the likelihood of a pigmented mole becoming malignant. During pregnancy, the shape and size of a mole often change. The following danger signs indicate that a pigmented mole has become malignant: changes in size, color, redness, whiteness, or blueness, especially the spread of the pigmented area to the surrounding normal skin; changes in surface features, texture, and shape; especially inflammation of the skin around the mole, which may manifest as bleeding, ulcers, itching, or pain.
