Basal cell carcinoma is the most common malignancy in man. These tumors rarely metastasize. Light exposure is the major risk factor. This cancer has the ability to grow over a wide area and penetrate deep into tissue. A growth or area that undergoes repeated cycles of healing and bleeding is suspicious for basal cell carcinoma. Some patients present with tumors of enormous size.
Most patients develop these tumors after middle age. Basal cell carcinoma can be found in patients in their 20s or 30s who have had excessive sun exposure and many sunburns.
