Basal cell carcinoma is the most common type of skin cancer to affect the human body. They oftentimes appear in sun exposed areas, like the face and the ears. Diagnosing basal cell carcinoma without a biopsy can be difficult. A bump that looks a little pearly, a bump that has blood vessels growing on it, or a bump that easily bleeds are all signs and symptoms of basal cell carcinoma. Only a biopsy can give you a definitive answer as to whether you have basal cell carcinoma or not, so if you have a suspicious lesion, see a dermatologist for a biopsy.
