Skin Cancer

Types of Skin Cancer

The three most common types of skin cancer include basal cell carcinoma, squamous cell carcinoma and melanoma. Basal cell carcinoma is the most common type overall. This type of cancer typically presents as a flesh-colored growth, small pearly bump or pink patch of skin. They are most common among those with fair skin and usually found on the head, neck or arms. Basal cell carcinoma is typically easy to treat, especially with early diagnosis.

Squamous cell carcinoma is the second most common. Squamous cell carcinoma typically looks like a firm red bump, scaly patch of skin or sore that does not heal or reopens frequently. Squamous cell carcinoma is most often found on the ears, face, neck, arms, chest or back, but can be found in any area of the body. Like basal cell carcinoma, it is highly treatable with early diagnosis.

Melanoma is a type of skin cancer that originates in the melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color. It is considered the most aggressive and dangerous form of skin cancer due to its tendency to spread rapidly to other parts of the body if not detected early. Melanoma often appears as an irregularly shaped mole or dark spot on the skin, although it can also develop in existing moles, causing changes in color, size, or shape. Early detection and treatment are crucial in managing melanoma, as it can be life-threatening if it progresses.

There are other, less common types of skin cancer. These include:

Cutaneous T-cell lymphoma
Dermatofibrosarcoma protuberans
Merkel cell carcinoma
Sebaceous carcinoma

Noncancerous Tumors

You may experience a number of types of noncancerous tumors of the skin. These growths are considered abnormal, but will not metastasize to other areas of the body. For this reason, noncancerous tumors are typically not life-threatening and are often not a serious health concern.

Some types of noncancerous skin tumors include:

Dermatofibroma
Hemangioma
Keratinous and pilar cysts
Lipomas
Moles
Seborrheic keratoses
Skin tags
Warts

What Causes Skin Cancer?

The underlying cause of skin cancer is a mutation in the skin cells’ DNA. These cause the cells to grow abnormally or out of control, forming a cancerous tumor or mass. These mutations may be caused by a number of factors.

Sun damage is a common cause of skin cancer. Over time, ultraviolet (UV) light from the sun or indoor tanning can cause damage to the skin cells. For this reason, it is important to wear SPF daily and seek shade as much as possible. This is also why those with fair skin, a history of sunburns or those who live in sunny climates are more susceptible to skin cancer.

Several factors may increase your risk for skin cancer in addition to your family history or skin tone. Those with a weakened immune system, including those taking immunosuppressant drugs or those with HIV/AIDS, are at an increased risk. Exposure to toxic substances can also increase your likelihood of developing skin cancer.

How is a Skin Cancer Biopsy performed?

A skin cancer diagnosis can be made through a biopsy. This involves removing a small amount of tissue which can be evaluated in a lab to make an accurate diagnosis. A biopsy will determine the type and stage of cancer you have and help inform the best treatment option. In some cases, the biopsy will remove all cancer cells and no further treatment will be necessary.

What are the Skin Cancer Treatment Options?

There are several treatment options that your provider may recommend for skin cancer.

Among the most common treatments for skin cancer is an excisional or Mohs surgery to remove all cancerous cells. In an excisional surgery, a scalpel or similar surgical tool is used to cut away the cancerous growth and a small margin of healthy skin cells to ensure that all cancer is removed.

In Mohs surgery, the cancerous growth is removed layer-by-layer and examined under a microscope. This helps to ensure that all abnormal cells are completely removed while sparing as much healthy skin as possible. Mohs surgery is particularly beneficial for larger or recurring skin cancer.

Cryotherapy, or freezing, may also be used to treat skin cancer. This involves freezing the unhealthy cells using liquid nitrogen, causing them to fall away.

Curettage and electrodesiccation is another option. In this procedure, a circular blade called a curet is used to scrape away layers of cancerous cells. An electric needle is then used to destroy any remaining cells.

In advanced cases of skin cancer, radiation, chemotherapy or biological therapy may also be necessary. This is less common.
