Lumps: Skin


Most skin lumps are normal and harmless. They can appear almost anywhere on the body. Most lumps are 'benign' – that is, they are not cancerous.

There are 7 types of common skin lumps:

  • BENIGN MOLES are small lumps with a smooth, even border. They are one color and can be beige, pink, or dark brown.
  • SKIN CANCER may appear as a small growth with fuzzy or irregular edges. A growth may be partly raised and partly flat. It may grow larger than the size of a pencil eraser. Any moles whose colors are mixed or are blue, gray, white, or black, and any mole that is very different from other moles on the body, should be medically evaluated. A person with a very large number of moles on the body should consider having more frequent medical checks.
  • WARTS are rough, hard bumps on the skin, often with a tiny, black center. Warts are caused by a virus and can spread from person to person. They are usually found on the hands and feet or on the anus, vagina, or penis.
  • CYSTS are abnormal lumps or swellings that are filled with fluid or semisolid material.
  • BOILS usually form around a hair follicle and are painful red bumps with a white or yellow center.
  • CORNS or CALLUSES are thickened bumps on a toe, bottom of the foot, or palm.
  • KELOIDS are a raised over-growth of healed scar tissue after a cut, injury, or surgery site.

Many of these problems are caused by or worsened by sun exposure. It is a good idea to protect the skin by avoiding long exposure to the sun. Use a sunblock with a safety protection factor (SPF) of 30 or higher. Also, wear hats or caps and long sleeves to protect your skin when working in the sun.

Seek medical evaluation for lumps that show signs of any of the following:

  • growth in size
  • change in color
  • change in shape around the edges
  • bleeding or
  • pain
