Malignant melanoma is a type of skin cancer that grows and spreads beneath the surface of the skin. It can develop on the foot where, unfortunately, it can go undetected during the early stage where treatment is most effective. Malignant melanoma is caused by overexposure of ultraviolet rays, and having numerous moles, fair skin, or a number of blistering sunburns can increase your risk.
Symptoms: Your doctor might suspect malignant melanoma if you have a mole or spot on your skin that is asymmetrical, has an irregular border, is a mix of shades, and grows in diameter.
Treatments: The best treatment for malignant melanoma on the foot depends on the stage of the cancer. Surgery to remove the mole and the area around it is performed. Immunotherapy drugs, chemotherapy, and radiation therapy are all methods of treatment that can be used.
You can help protect yourself from malignant melanoma of the feet by wearing sunscreen on your feet when they will not be covered by shoes. You should also inspect your feet regularly to check for moles or changes.
