Hello, my mother has lots of warts all over her body, since she was little. The thing is, one of these warts has developed a sort of growth on it. It's a small round dark brown coloured growth, it actually looks like a mole, but it's on her wart. It appeared a few months ago and it seems to come and go but I am worried because I don't know if it could be cancer. I've always thought you had to look and check for changes in moles, but I don't know if warts can become cancerous. Thanks in advanced for answering.
Common warts tend to occur in hands and feet, and in other areas like elbows or knees.
They are caused by so called cutaneous HPV and these types of HPV do not have a cancerous potential.
Warts that appear on the face, forehead and arms and look like a reddish-brown or flesh-colored, slightly raised bumps, are known as flat warts. When the affected person has normal immune system, there is no risk for cancerous transformation.
Your mother even if there is no risk for cancer, should see dermatologist for treating the warts!
