Skin cancer -- abnormal cell changes in the outer layer of skin -- is by far the most common cancer in the world. It can usually be cured, but the disease is a major health concern because it affects so many people.

How does skin cancer first appear?

Skin cancer may initially appear as a nodule, rash or irregular patch on the surface of the skin. These spots may be raised and may ooze or bleed easily. As the cancer grows, the size or shape of the visible skin mass may change and the cancer may grow into deeper layers of the skin.

When does skin cancer develop?

Age. Most basal cell and squamous cell carcinomas typically appear after age 50. However, in recent years, the number of skin cancers in people age 65 and older has increased dramatically. This may be due to better screening and patient tracking efforts in skin cancer.

Email. It’s difficult to say what exactly causes skin cancer, but basically, skin cancer occurs when something goes wrong during the body’s production of skin cells. Typically, the body’s skin cells grow old or become damaged over time, and normal cells grow and divide to form new, healthy cells to take their place.

What is the most common type of skin cancer?

Basal and squamous cell carcinomas are the two most common types of skin cancer. They begin in the basal and squamous layers of the skin, respectively. Both can usually be cured, but they can be disfiguring and expensive to treat. Melanoma, the third most common type of skin cancer, begins in the melanocytes.

Where does skin cancer start?

Skin cancer begins in the epidermis, which is made up of three kinds of cells—. Squamous cells: Thin, flat cells that form the top layer of the epidermis. Basal cells: Round cells under the squamous cells. Melanocytes: Cells that make melanin and are found in the lower part of the epidermis . Melanin is the pigment that gives skin its color.

What are the cells that make melanin?

Melanocytes: Cells that make melanin and are found in the lower part of the epidermis. Melanin is the pigment that gives skin its color.

Even when chemotherapy shrinks these cancers, the cancer usually starts growing again within several months.

Can stage 3 melanoma be cured?

Other possible treatments might include targeted therapy (for melanomas with a BRAF or C-KIT gene change), immunotherapy, or chemotherapy.

What is the most common cancer on the face?

Basal cell carcinoma (basal cell cancer) mainly affects people over the age of 60 and is most commonly found on the face, neck or other parts of the head that are regularly exposed to sunlight. It usually grows slowly and stays in the area where it first developed. So it's generally discovered at a stage where it can still be completely removed during surgery. But it's not totally harmless: If it's only treated very late, or not treated at all, it can enter deeper layers of tissue. This can cause damage to things like your nose, eyes and facial bones.
