Depends on subtype. Solitary pearly nodule with rolled border, with small overlying blood vessels (telangiectasias), often ulcerated, bleeds easily. The lesions are normally found on sun-exposed areas such as the face and arms. The tumors are slow-growing, non-aggressive, and they rarely metastasize. Common basal cell carcinoma subtypes include: nodular, superficial, pigmented, infiltrative, & sclerosing.
Basal Cell Cancer. Basal cell carcinoma (aka bcc or rodent ulcer) is the most common type of skin cancer and may present in a variety of forms: nodular (or nodulo-cystic), ulcerating, sclerosing, multi-centric and pigmented (higher incidence in darker complected individuals). It is most commonly associated with extensive sun exposure. Spread is by local invasion of neighboring tissues. Treatment is primarily surgery.
