What are the obvious symptoms of melanoma?

The obvious symptoms of melanoma mainly include: 1. Melanin deposition: In the early stages, melanoma often presents as melanin deposition on the skin, possibly in the form of pigmented spots or moles, which can be easily overlooked. 2. Itching and pain: As the condition progresses, abnormal sensations such as itching or pain may develop in the melanoma area, and the color may gradually darken. 3. Lump: A progressively enlarging hard lump can be felt at the site of the melanoma, and the lump may gradually protrude from the skin surface. 4. Bleeding and discharge: Bleeding, discharge, or pus may appear on the surface or surrounding area of the melanoma, especially in the absence of external force or other obvious causes. These symptoms are the main manifestations of melanoma, but they may vary among individuals. If you have related concerns, please seek medical examination promptly.
