Feet are particularly sensitive to sunburn! Usually enclosed in closed toe shoes, feet can burn easily when exposed to the sun, which can lead to cancer. Yes, the foot and ankle are as susceptible to skin cancer as any other part of the body. Melanoma, the deadliest form of skin cancer, can also strike the foot and ankle, where it is likely to go unnoticed or be misdiagnosed.

A shocking study entitled Survival of patients with primary pedal melanoma, which appeared in the July 2003 issue of the Journal of Foot & Ankle Surgeons, found that the overall 5-year survival rates for patients with melanomas of the foot or ankle was only 52% compared to the 84% survival rate for those with melanomas on other parts of the lower extremity.

“The dramatically lower rate of survival is most likely attributed to late diagnoses. according to Dr. Daniel Altchuler, a podiatric physician and surgeon in Santa Monica, California. “A odd spot on the foot that does not hurt, particularly on the sole of the foot, is unlikely to be noticed until the cancer has reached an advanced and more deadly stage.

“Anyone who spends a lot of time in the sun in sandals or barefoot should check their feet regularly (and thoroughly) for suspicious moles or pigment changes. Even members of groups that typically have lower risks of skin cancer (African-Americans, Asians, and Hispanics) can develop melanomas on their feet.

“Remember to apply a good sunscreen with a protection factor of at least 15 to both the bottom and tops of your feet, and to have your doctor examine your feet - top and bottom - during your next checkup.

“Diabetics must be especially careful about exposing their feet to the sun, should never go barefoot., and should have their feet checked by a podiatric physician (foot and ankle specialist) at least once a year.” said Altchuler.

More tips from CPMA on protecting your feet in the sun.

Limit the amount of time you spend in the sun between the hours of 10 AM and 4 PM. This is when the sun's rays are the strongest.
If you have to be in the sun wear closed toed shoes.
Protect yourself during any outdoor activity with a sunscreen that has a Sun Protection Factor (SPF) rating of 15 or higher.
Apply sunscreen about ½ hour before you go into the sun. This allows the sunscreen to seep into the upper skin layers, giving you better protection.
Reapply sunscreen (even waterproof sunscreen) every 2 hours, especially if you're swimming or sweating.
Some medications can make you more sun-sensitive, including oral contraceptives, antibiotics, skin treatments, and medications for blood pressure, arthritis, and depression. Read the labels on your medications and talk with your doctor, to see what extra steps you may need to take when you're in the sun.
