Clinical Causes: Prolonged exposure to ultraviolet (UV) rays from the sun or tanning beds. History of sunburns, especially severe or frequent incidents. Immune system suppression, which can be due to medications or medical conditions. Presence of fair skin, light hair, or light eyes, which increases susceptibility. Chronic skin injuries or sores that do not heal properly. Genetic factors and family history of skin cancers. Exposure to certain chemicals or carcinogens in the environment.

Key Symptoms: A new or changing skin lesion or growth that may be firm, nodular, or ulcerated. A sore that does not heal or keeps returning. A persistent growth or lump that may be red, shiny, or scaly. Change in color, size, or shape of an existing mole or lesion. Skin ulcer or sore that bleeds or crusts over. Unexplained skin discomfort or itching in the affected area.

Diagnosis Path: Diagnosis typically involves a physical examination of the skin lesion, followed by biopsy to confirm malignancy. Imaging studies may be used to determine the extent of spread if there is concern about deeper tissue involvement or metastasis. The healthcare provider assesses the lesion's characteristics, history, and risk factors to establish an accurate diagnosis, often confirmed through histological analysis of tissue samples.

Treatment Protocols: Surgical excision to remove the tumor and some surrounding healthy tissue. Mohs micrographic surgery for precise removal, especially in cosmetically sensitive areas. Radiation therapy to target residual cancer cells or if surgery isn't feasible. Topical medications or cryotherapy for superficial lesions. Systemic therapies, such as targeted therapy or immunotherapy, if the cancer has spread. Regular follow-up examinations to monitor for recurrence or new lesions.
