How can you tell the difference between squamous cell carcinoma and actinic keratosis?

One important clue in visual inspection and differentiation between SCC and AK is the size of the lesion. Generally AK lesions tend to be smaller than SCC lesions. Invasive SCC typically is a tender, enlarging hyperkeratotic lesion that may become nodular and ulcerate.

Does actinic keratosis spread quickly?

How do you reverse actinic damage?

Can you leave actinic keratosis alone?

AKs tend to start out small, but they can grow if you leave them alone. Dermatologists usually recommend that you have your AKs removed. While an AK in and of itself is not harmful to your health, it can develop into squamous cell carcinoma, an extremely dangerous form of skin cancer.

How long can a person live with squamous cell carcinoma?

Squamous cell carcinoma (SCC) generally has a high survival rate. The 5-year survival is 99 percent when detected early.
