What are the early symptoms of melanoma?

If melanoma is not discovered and treated early, it can actually be a direct threat to life, so you should pay attention to the early symptoms of melanoma, such as bumps or plaques, nodules, and changes in size and color.

1. Melanoma is a relatively common skin disease. It occurs more frequently in middle-aged and elderly people and is more common in men than in women. The disease is most common in the lower limbs and feet, followed by the trunk, head and neck, and upper limbs. So what are the early symptoms of melanoma? The early symptoms of melanoma - initially, normal skin develops melanin deposition, or pigmentation of moles increases, the black color deepens, and then the lesions continue to expand, the hardness increases, and they are accompanied by itchy and painful sensations. Melanoma lesions may appear as raised, plaque-like or nodular shapes, or as mushroom-like or cauliflower-like shapes. When it grows into the subcutaneous tissue, it appears as a subcutaneous nodule or lump. If it spreads to the surrounding areas, it appears as star-shaped black spots or small nodules. A common manifestation is regional lymph node metastasis of melanoma, and some patients may even seek medical attention due to enlarged regional lymph nodes. In the late stage, the disease is transferred through the bloodstream to the lungs, liver, bones, and brain.

2. Most malignant melanomas originate from melanocytes in normal skin . Malignant melanoma is rare in children, but can originate from very large pigmented nevi that are present at birth. Halo nevi usually disappear on their own but in rare cases they may become melanomas. Although melanoma is more likely to occur during pregnancy, pregnancy does not increase the likelihood of a mole turning into melanoma. Moles often change in shape and size during pregnancy.

3. The following danger signs indicate that a pigmented nevus may 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 inflammatory reactions in the skin around the nevus, which may result in bleeding, ulcers, itching, or pain. What are the early symptoms of melanoma? It is mainly the deposition of melanin, and special attention should be paid to some signals from moles. Color: Variegated colors are a sign of malignancy. The freckle type and superficial spreading type are often mixed with red, white or blue in brown or black, among which blue is particularly bad. Edge: often jagged and serrated, due to the spread of the tumor or spontaneous degeneration. Surface: Not smooth, often rough with scaly flaky desquamation, sometimes with bleeding and exudation, and may be higher than the skin surface. Skin around the lesion: may become edematous or lose its original skin luster or turn white or gray. Paresthesia: local itching, burning or tenderness.
