Non Melanoma Skin Cancer
There are two main types of nonmelanoma skin cancer, Basal cell carcinoma
(BCC) and Squamous cell carcinoma
. Though they are rarely life-threatening, nonmelanoma skin cancers can be disfiguring when not diagnosed and treated in a timely manner.
Basal cell carcinoma (BCC)
is a nonmelanocytic skin cancer (ie, an epithelial tumor) that arises from basal cells (ie, small, round cells found in the lower layer of the epidermis).
- Red, tender, flat spot that bleeds easily.
- Waxy papules with central depression
- Erosion or ulceration: Often central and pigmented
- Patch of skin, especially on the face, that looks like a scar and is firm to the touch.
- Slow growing: 0.5 cm in 1-2 years
- Change in the size, shape, or color of a mole or a skin growth.
Squamous cell carcinoma
is a common form of skin cancer that develops in the thin, flat squamous cells that make up the outer layer of the skin. It`s usually not life-threatening, though it can be aggressive in some cases.
- A new sore or raised area on an old scar or ulcer
- Persistent, firm, red bump on sun-exposed skin.
- Skin growth that looks like a wart-like sore on or in the anus or on your genitals
- A rough, scaly patch on your lip that may evolve to an open sore
Treatment of nonmelanoma skin cancer depends on the type and location of the skin cancer, the risk of scarring, as well as the age and health of the patient. Methods used include curettage and desiccation, surgical excision, cryosurgery, radiation, and Mohs micrographic surgery.
