Skin cancer is a type of cancer that begins in the skin cells. The skin is the body’s largest organ and plays a crucial role in protecting the body from external factors such as sunlight, infection, and injury. There are three main types of skin cancer: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma.
- Basal Cell Carcinoma (BCC): This is the most common type of skin cancer. It usually occurs in areas of the skin that are frequently exposed to the sun, such as the face and neck. BCC often appears as a pearly or waxy bump and may bleed easily.
- Squamous Cell Carcinoma (SCC): SCC is also linked to sun exposure, and it commonly occurs on the face, ears, and hands. It may appear as a firm, red nodule or a flat, scaly lesion. SCC has the potential to metastasize (spread to other parts of the body), although it’s less likely than melanoma.
- Melanoma: Melanoma is less common than BCC and SCC but is more aggressive. It arises from pigment-producing cells (melanocytes) and can occur anywhere on the skin. Melanomas often have irregular borders, uneven color, and may change in size or shape. Early detection is crucial for successful treatment, as melanoma can spread rapidly.
