Skin Cancer
Skin cancer is the uncontrolled growth of skin cells. There are 3 types of skin cancer — basal cell carcinoma, squamous cell carcinoma, and melanoma.
Symptoms
The most common symptom is a non-healing ulcer on the skin. A change in the size, shape, or color of an existing lesion on the skin can be a warning sign of cancer.
Diagnosis
If there is suspicion of skin cancer first thing done is a biopsy of the ulcer. The biopsy will prove or disprove the diagnosis of cancer. Imaging like a PET scan may be done to see the extent of the spread of cancer.
Treatment
Surgery is the main modality of treatment. This involves removing the Cancer with surrounding healthy skin. In late stages Chemotherapy and radiation is required to cure cancer.
