GENERAL HISTOLOGY

Detailed explanation-1: -Melanoma is not as common as basal cell or squamous cell carcinomas but is the most dangerous form of skin cancer. If left untreated or caught in a late-stage, melanomas are more likely to spread to organs beyond the skin, making them difficult to treat and potentially life-limiting.

Detailed explanation-2: -Merkel cell carcinoma tends to grow fast and to spread quickly to other parts of your body. Treatment options for Merkel cell carcinoma often depend on whether the cancer has spread beyond the skin.

Detailed explanation-3: -Basal cell carcinoma is a type of skin cancer that most often develops on areas of skin exposed to the sun, such as the face. On brown and Black skin, basal cell carcinoma often looks like a bump that’s brown or glossy black and has a rolled border.
