Melanoma is the most serious form of skin cancer and can also develop in areas of the body that are rarely exposed to sunlight.
The feet are one of the areas many people overlook, which can delay the detection of the disease, according to the American Academy of Dermatology.
Anyone can be affected
Melanoma on the foot can occur in people of all skin tones and ethnic backgrounds.
Feet are an important area
Among people of African or Asian descent, the feet and hands are among the most common locations where the disease can develop.

Early checks can make a difference
Regular foot examinations can help detect changes before the disease has a chance to progress further.
The entire foot should be examined
It is important to look for changes on the toes, soles, heels, nails, and between the toes.
Old injuries require attention
Areas where the foot has previously been injured should be checked especially carefully.
Previous injuries may matter

A new spot or growth on the foot should not be ignored.
Rapid growth can be a warning sign
A lump or change that grows quickly may be an indication that something is wrong.
Sores that do not go away
