Foot melanoma is a type of skin cancer that affects the feet. It can appear anywhere on the foot, including the sole or under a nail. It starts in a skin cell called a melanocyte.

These cells are located in the uppermost layer of the skin. They are responsible for producing melanin, a dark pigment that helps screen the body against the harmful effects of ultraviolet light.

Foot melanoma is often treatable in the early stages, but it is often diagnosed late because people do not notice it. If it spreads, it can be life-threatening.

  • Foot melanoma is a rare but serious form of skin cancer.
  • It constitutes 1% of skin cancers but more cancer deaths than any other type of skin cancer.
  • Between 3 and 15% of melanomas occur on the foot.
  • The first symptom in most cases of foot melanoma is a changing or unusual mole.
  • Check symptoms with the acronym CUBED. Is it Colored, Uncertain, Bleeding, Enlarged, or is there Delay in the healing of lesions?


  • Colored: A lesion has a color different to normal skin.
  • Uncertain: A lesion does not have a definite diagnosis.
  • Bleeding: A lesion on the foot or under the nail bleeds or oozes fluid.
  • Enlargement: A lesion or ulcer that grows or worsens despite therapy.
  • Delay: Any lesion that takes longer than 2 months to heal.

Other warning signs for foot melanoma include:

  • a sore that does not heal
  • pigment spreading from the border of a lesion to surrounding skin
  • redness or new swelling beyond the border of a lesion
  • change in sensation such as itchiness, tenderness, or pain
  • change in the surface of a mole including scaliness, oozing, bleeding, or the appearance of a bump or nodule

If two of the above are present, the doctor will normally refer the patient to a specialist for further assessment.
