Even though your feet may not get a lot of sun exposure, they can still be susceptible to developing cancerous lesions just like other parts of your body. Cancers of the feet are not always related to UV exposure and can also be caused by chemical exposure, viral infection, and chronic skin irritation.
Cancers that can affect your feet and ankles include the following:
Melanoma—This is by far one of the most fearsome and deadly of cancers. A malignant melanoma will grow deeper into the skin where it can rapidly spread to other parts of the body by way of the blood vessels and lymphatic system. Melanomas can grow on the bottom of the feet and even underneath the toenails where it can be mistaken for a fungal nail infection. Malignant foot tumors can also look like blisters, warts, and moles, so always have any skin abnormalities carefully checked by your foot doctor.
Basal cell carcinoma—This type of cancer is rarely seen on the feet since it tends to be specifically linked to sun exposure. It is much less aggressive than malignant melanoma and is seldom a candidate to spread past the skin layers.
Squamous cell carcinoma—Painless, itchy bumps are one of the telltale signs of this cancer and it can often take on the appearance of plantar warts. Since it may also resemble a fungal infection, always have your podiatrist do a complete inspection.
