Final answer:
A shiny bump with a pearly edge on a patient is indicative of basal cell carcinoma, the most common skin cancer. These carcinomas typically arise in the epidermis' basal cells and are best treated when caught early.
Step-by-step explanation:
A patient with a shiny bump that has a pearly edge is exhibiting signs of basal cell carcinoma, which is the most common type of skin cancer. Basal cell carcinoma originates from basal cells in the stratum basale layer of the epidermis. Although basal cell carcinomas do not typically metastasize, it is crucial to diagnose and treat them early. The standard treatment for basal cell carcinoma involves a biopsy to remove and analyze the lesion.
This type of cancer is frequently found on body parts most exposed to sun, such as the head, neck, arms, and back. The appearance of a pearly or waxy bump is a hallmark of basal cell carcinoma and contrasts with the appearance of melanoma, which usually presents as asymmetrical brown and black patches with uneven borders and a raised surface. Skin cancer treatments range from surgery to cryosurgery and topical ointments, depending on the type and stage of the cancer.
