In Houston, where bright sunshine is an almost year-round likelihood, Skin Cancer Awareness is very important. So, with some help from the Centers for Disease Control (CDC), I want to call your attention to the fact that you could have skin cancer on your feet and not experience any foot pain.
Even if you have regular skin checks to rule out skin cancer, many examinations forget the delicate skin on the tops and bottoms of your feet. And it's important to carefully examine these areas in a very special way.
This is How to Perform a Skin Cancer Check of Your Feet
Skin cancer on your feet is a little different than on the rest of your body, as it is more frequently caused by a virus than by exposure to the sun (especially when it manifests on the bottom of your feet.) Your Houston podiatrist is trained to look out for unusual skin patches on the foot and may be better equipped to make the cancer diagnosis than a regular dermatologist.
If you are doing a home skin cancer exam (which I highly recommend), you should know the following common features of skin cancers of the feet:
- Feet that keep cracking, itching or bleeding (cancer may have been present for a while but, since it is painless, these signs may be the only recognizable manifestation.)
- Non-healing sores, bumps that crack and/or bleed, nodules with rolled edges or scaly areas may all be indications of skin cancer of the feet.
- Pearly white bumps and or oozy patches that get crusty could be indicators of basal cell cancers. On the foot, basal cell cancers can often be mistaken for non-cancerous skin tumors or benign ulcers.
- Small, scaly bumps (possibly appearing to be inflamed) can be a sign of early-squamous cell carcinoma, the most common type of skin cancer of the foot. Painless but itchy, this type of cancer is often misdiagnosed as a plantar wart, fungal infection, eczema, or ulcer. If caught early, it can usually be contained to the skin of the foot but, if left untreated, this cancer can spread and become deadly.
Diagnosing and Treating Skin Cancer of the Foot
The only way to confirm whether or not an unusual patch of skin on tour foot is cancerous is to have your podiatrist perform a skin biopsy, which is a simple procedure in which a small sample of skin is obtained and sent to a lab for a skin pathologist to examine. If the biopsy determines you have skin cancer, your podiatrist will help you determine your next course of action.
Each year, about 2 million Americans are diagnosed with non-melanoma skin cancers. The goal of Skin Cancer Awareness is to promote early detection and treatment, so if you see any suspicious spots on the skin of your feet or anywhere else on your body, schedule an appointment to see Houston podiatrist Dr. Andrew Schneider immediately.
