But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma.

What are the main skin cancers?

The main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), melanoma and Merkel cell carcinoma (MCC). The two main causes of skin cancer are the sun’s harmful ultraviolet (UV) rays and the use of UV tanning beds.

Which skin cancer is most common?

Basal cell carcinoma (also called basal cell skin cancer) is most common type of skin cancer. About 8 out of 10 skin cancers are basal cell carcinomas (also called basal cell cancers). These cancers start in the basal cell layer, which is the lower part of the epidermis.

Which is worse basal cell or squamous cell cancer?

Though not as common as basal cell (about one million new cases a year), squamous cell is more serious because it is likely to spread (metastasize).

What is the most aggressive form of skin cancer?

Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage.

What does Stage 1 skin cancer look like?

Squamous Cell Carcinoma Early Stages

At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface. These abnormal cells slowly grow in sun-exposed areas.

What is the difference between a basal cell carcinoma and a melanoma?

Melanoma typically begins as a mole and can occur anywhere on the body. Squamous cell carcinoma may appear as a firm red bump, a scaly patch, or open sore, or a wart that may crust or bleed easily. Basal cell carcinoma may appear as a small white or flesh-colored bump that grows slowly and may bleed.

How can you tell if a spot is cancerous?

Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesn’t go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.

How do I know if I have basal cell or squamous cell carcinoma?

Basal cell carcinoma most commonly appears as a pearly white, dome-shaped papule with prominent telangiectatic surface vessels. Squamous cell carcinoma most commonly appears as a firm, smooth, or hyperkeratotic papule or plaque, often with central ulceration.

What happens if Basal cell carcinoma is left untreated?

If left untreated, basal cell carcinomas can become quite large, cause disfigurement, and in rare cases, spread to other parts of the body and cause death. Your skin covers your body and protects it from the environment. Your skin is composed of three major layers, the epidermis, dermis, and subcutaneous tissue.
