Question

Why does pulling hair from moles feel so good?

Answer 1

There have been erroneous ideas and old wives' tales that plucking hairs from moles can cause them to turn cancerous, but physicians in the field of dermatology and oncology insist that this is merely because occasionally people have blamed the fact that they may have plucked a hair from a mole which later coincidentally became cancerous for causing the cancerous state.
 
It is advised that you always make sure to avoid exposing moles to the sun, and you should be sure to use sunscreen on any exposed moles (as well as the rest of the skin) when you plan to be outside.

of course, the physical shape of a mole can dictate taking special precautions when dealing with that area of the skin. If the mole is textured or raised, you will want to use care when shaving over the area so that you prevent nicks and cuts that can become infected.
