Basal cell carcinoma


Basal cell carcinoma
Over 90% of basal cell carcinomas occur in fair-skinned, blue-eyed individuals over the age of 40. The lesions form on sun exposed areas such as the eyelids, bridge of the nose, hands, or forearms. They appear translucent and red, with a rolled border. They usually reach 1 cm to 3 cm in size before they ulcerate and bleed. They often have a central ulceration. They are very slow-growing cancers, taking months to years to grow, and they never spread to other parts of the body. They can be cured with topical chemotherapy, radiation, or surgery. Since they are related to a lifetime of sun exposure, there is a 40% chance of new basal cell cancer occurring over a five-year period after initial treatment.
