Malignant melanoma is a type of skin cancer that can develop on the foot. It can occur on any part of the foot, including the soles, nails, and between the toes. The signs and symptoms of melanoma of the foot include:
- A new mole, bump, or spot on the foot that is changing in size, shape, or colour
- A sore that does not heal
- A pigmented band that runs under the nail and extends onto the adjacent skin
- A dark spot or streak that grows in size or changes in colour
- A nodule, lump, or bump on the foot that is not painful but keeps growing
If you notice any of these signs or symptoms on your foot, you should see a podiatrist or dermatologist for evaluation. Early detection and treatment are important for the successful management of melanoma of the foot.
