Basal cell carcinoma:
Usually looks like a raised, smooth, pearly bump on the sun-exposed skin of the head neck or shoulder. Crusting and bleeding in the centre of the tumor frequently develops. It is often mistaken for a sore that does not heal. This form of skin cancer is the least deadly and can be cured completely by surgery.
Squamous cell carcinoma:
Commonly a red, scaling, thickened patch on sun-exposed skin. Ulceration and bleeding may occur. When Squamous cell carcinoma is not treated, it may develop into a large mass. This is the second most common skin cancer. It is dangerous, but not nearly as dangerous as Melanoma. These are also treated with surgical excision.
Melanomas:
They are brown to blackish lesions. Signs that might indicate a malignant melanoma include change in size, shape, color or elevation of a mole. Other signs are the appearance of a new mole during adulthood or new pain, itching, ulceration or bleeding.
