Major Types of Skin Cancer Non Melanoma and Malignant Melanoma Types
The different types of skin cancer vary according to the types of cell where the malignant growth develops. There are 2 major forms of skin cancers - Non Melanomas and Melanoma. The non-melanomas have two main types: Basal cell and Squamous cell cancers. Abnormal moles are one of the signs of melanoma.
What are the different types of non-melanoma skin cancer?
The non-melanoma types include . . .
1. Basal Cell Carcinoma - The cancer starts in the basal cells found at the base of the outer layer called the epidermis.
Basal cell is the least serious but the most common among the various types. In fact, majority of cases diagnosed in the United States are Basal Cell Carcinoma. It grows slowly and is locally invasive. It rarely spreads to the rest of the body.
2. Squamous Cell Carcinoma - The tumor develops in the squamous cells located in the outermost part of the epidermis. It is more serious compared to Basal Cell Carcinoma because it grows very fast.
