Skin Cancer

Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma.
Squamous Cell Carcinoma
This presents as a fungating, irregular fleshy growth usually on sun exposed skin. The growth can increase rapidly in size giving rise to a large lump which may sometimes break down to form an ulcer. If untreated, the cancer may spread to the adjacent skin and lymph nodes. Chronic sun exposure is an important contributing factor in the development of this type of skin cancer.
Basal Cell Carcinoma
This is a slow growing painless skin cancer. The cancer often presents as an indolent ulcer with a shiny or translucent raised margin. The ulcer is often pigmented. This cancer commonly appears on the upper half of  face.
Malignant Melanoma
This is a cancer of the pigment cells of the skin. It is a highly malignant skin cancer. It presents as dark brown or black skin growth or ulcer. It may look like ordinary moles. But unlike the common mole it grows rapidly, large in size and may also bleed on touch.
Treatment for skin cancers
All skin cancers should be removed immediately. The cancerous tumors must be destroyed or removed surgically. Sometimes, a small piece of the tumor is removed (skin biopsy) first for examination to confirm if it is cancerous.
