Ive flat warts on my hands legs meaning top of feet and back of heel area. i know ive had the arm/hands ones for awhile. is it accurate that these are simply benign and at no risk for cancer?

Wart strains that produce these do not pose a cancer brisk.

While the warts that you have are not a cancer risk, you should take HPV vaccine to prevent infection with cancer causing strains of HPV. Wish you good health!

Additionally, see a trusted dermatologist who can provide immunization as well as a total body check, which at you age should be performed annually.
