Cancerous Skin Lesions Before Skin Cancer

There are four major types of pre-cancerous lesions to watch out for. The first of which is acitinic keratosis, which is the result of chronic sun exposure, and is usually found on fair skinned individuals. With this type of lesion, the affected areas are flat, rough and feel like sandpaper. Acitinic keratosis has the potential to turn into squamous cell cancer.

A rare pre-cancerous lesion is Atypical Fibroxanthoma (AFX). It typically forms on the scalp or ears, and is more usually seen on the elderly as a result of years of sun exposure. The lesion must be removed to ensure it does not return. Usually, you will have to observe that area for a year or two after.

The next type of precancerous skin lesion is Melanoma-in-situ, which is considered a precursor to melanoma. Melanoma-in-situ is not invasive by nature, and his typically found in the skin’s surface.

Atypical moles can be precancerous lesions that are benign to begin with but become malignant. Biopsies must be performed on irregular moles that change in size, shape or texture to prevent the development of skin cancer.
