Description

Skin cancer refers to the abnormal growth of skin cells, typically as a result of damage to the DNA of the skin cells caused by exposure to ultraviolet (UV) radiation from the sun or other sources. There are several types of skin cancer, including: 1. Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer. It usually appears as a slow-growing, raised, pearly bump or a pinkish patch of skin. 2. Squamous Cell Carcinoma (SCC): SCC is the second most common type of skin cancer. It typically appears as a firm, red nodule or a scaly, crusty growth. 3. Melanoma: Melanoma is a more aggressive form of skin cancer that originates in the pigment-producing cells of the skin. Other less common types of skin cancer include Merkel cell carcinoma, dermatofibrosarcoma protuberans, and various types of lymphomas and sarcomas that can occur in the skin. Prevention of skin cancer involves taking measures to protect the skin from excessive UV radiation exposure, such as wearing protective clothing, seeking shade, and using sunscreen with a high SPF. Treatment for skin cancer depends on the type, stage, and location of the cancer. Common treatment options include: * Surgical excision: Removal of the cancerous lesion along with a margin of healthy tissue. * Mohs surgery: A specialized surgical technique used for certain types of skin cancer, particularly those with high recurrence rates or in challenging locations. * Radiation therapy: The use of high-energy radiation to destroy cancer cells. * Topical therapies: Medications applied directly to the skin, such as creams or gels, to treat superficial skin cancers. * Chemotherapy: Systemic medications that kill cancer cells or slow their growth. * Immunotherapy: Medications that stimulate the body's immune system to recognize and destroy cancer cells. The choice of treatment depends on various factors and should be determined by a healthcare specialist.
