It is best not to surgically remove a keloid if you want to get rid of it. This is because after surgical removal, although the keloid in the moment is removed, a new kind of keloid may form due to the surgery. Therefore, if the keloid is not very obvious, it is best not to remove it surgically. Keloid scars are usually treated with hormone injections, usually Depo Provera, into the scar tissue. After the keloid tissue absorbs Depo Provera, the hormone causes the collagen fibers in the keloid tissue to degenerate to a certain degree and develop into fibroblasts or other epithelial cells, which softens the scar to a certain degree and also controls the proliferation of scar tissue.
