Bruce Jenner May Have Skin Cancer, Report Says -- What Are The Risks?

According to reports from TMZ, Bruce Jenner -- the stepfather of the Kardashian sisters -- has had skin cancer removed from his face.

TMZ said that sources say Jenner reportedly went to the doctor because of a red mark on his face; the doctor conducted a biopsy and found that it was skin cancer.

The doctor reportedly also told Jenner to wear a hat when going out in the sun to golf, according to TMZ.

While Jenner himself has yet to confirm the news -- so we are taking it with a grain of salt -- it's a good reminder to protect our skin from the skin so we can decrease the risk of skin cancer. The Mayo Clinic reports that skin cancer most commonly develops on sun-exposed skin, though it can also develop on other parts of the body.

According to the National Institutes of Health, skin cancer is most common in people who are over age 50, get sunburned or spend a lot of time under the sun, have light skin, hair or eyes, or have a family history of the disease.

Skin cancer is the most common cancer in the United States, according to the Centers for Disease Control and Prevention. In 2007, 58,094 people had melanoma, and 9,461 people died from the melanoma.

There are several different kinds of skin cancer, but basal cell carcinoma and squamous cell carcinoma are the most common types, according to the National Institutes of Health. They usually occur on the head, neck, arms and hands. Melanoma is another form of skin cancer that is more dangerous than these two types.

Basal cell carcinoma usually manifests as a pearly bump or a flat brown- or flesh-colored lesion, according to the Mayo Clinic. Squamous cell carcinoma appears as a red, firm nodule or a flat, crusted lesion.

Melanoma usually appears as a mole that has changed color or size, or that bleeds, or as a large brown spot that has speckles. Other legions that are dark or have irregular borders could also be a sign of melanoma, the Mayo Clinic reported.

To diagnose skin cancer, a doctor will look at the suspicious mark on the skin, and may do a biopsy -- where part of that region of skin is removed, according to the Mayo Clinic. Treatments include surgery -- where the cancer and some surrounding skin, or bottom layers of skin, are removed -- as well as radiation therapy or chemotherapy. Other therapies -- like light therapy, biological medications and freezing off early cancers -- are also options.

To protect your skin from the sun's dangerous ultraviolet rays, it's important to cover your skin with shade and put on lots of sunblock. People should look for sunscreens that have an SPF of 15 or higher, that also say "broad spectrum," the Associated Press reported.
