Signs of melanoma cancer

Melanoma cancer symptoms

1. Asymmetry: One half of the mole looks asymmetrical with the other half.

2. Irregular edges: The edges are irregular or have notches, serrations, etc., or satellite lesions appear. They do not have a smooth round or oval outline like a normal pigmented nevus.

3. Color change: Normal pigmented moles are usually solid color, while melanoma mainly appears as dirty black, but can also appear in a variety of different colors such as brown, brown, brown-black, blue, pink, black and even white.

4. Diameter: Pay attention when the diameter of the pigmented spot is larger than 6 mm or when the pigmented spot grows. Melanoma is usually larger than ordinary moles. Be careful of pigmented moles with a diameter larger than 6 mm and smooth appearance. Especially pigmented moles occurring on the extremities of the hands and feet are best removed and examined under a microscope.

5. Bulging: In some early melanomas, the entire tumor will have a slight bulge.

6. Growth rate: Some pigmented nevi that have not changed for many years may grow significantly larger within a few weeks or months.

7. Shedding: The hair that has been growing on the pigmented nevus suddenly falls off, or the ulcer is difficult to heal.
