i have a mole on my upper chest since 5-7 years, The size of the mole has grown bigger and bumpy, pus and it has foul odor. I used to squeezed it and let pus out but now a days it became little hard to squeeze and very little pus comes out. The size of the mole or bump is the same size as an eraser of a pencil. and it is same skin color as my body but bumpy and in the middle it has small black hole that releases pus. I have no pain on the mole.
