Itching, dry skin, and sensitivity are really not signs of moles becoming skin cancers. The changes due to cancer are mostly visual until it is far advanced. Please use the ABCDE's as your guide for when to be
concerned about moles: A for Asymmetry; B
for irregular Borders; C for black or
uneven Colors; D for Diameter greater
than a pencil eraser; and E for a
growth that is Evolving or changing. However, even moles on the scalp that never see the sun can turn into skin cancer. If you are still concerned it is an extremely simple five minute
procedure for a dermatologist to remove the mole using a "shave" biopsy which typically leaves a
minimal scar. The mole can then be checked microscopically for reassurance.

changes in moles that are suspicious for skin cancer.
