Age spots, also known as liver spots or sun spots, are common, harmless skin lesions that are caused by sun exposure. They typically appear on areas of the skin that have been exposed to the sun, such as the face, hands, and forearms. Age spots are usually flat, oval-shaped, and brown or gray in color. They can vary in size, from a few millimeters to several centimeters in diameter.
Skin cancer, on the other hand, is a malignant growth of skin cells. It is the most common type of cancer, and it can be life-threatening if not detected and treated early. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer, and they are usually curable if treated early. Melanoma is the most serious type of skin cancer, and it can be deadly if not treated early.
