<s>[INST] There is a hard white ball on the edge of a fairly new scar on my forehead. Looks like a big whitehead but won t pop. No pain or itching comes from the spot. Just wondering if it is extra scar tissue or something else? Also, can it be removed or will it go away with time? [/INST] thanks for sharing your health concerns with us!you have to mention the size of the lumps; however, possibilities are: a sebaceous cyst or a keloid like thing! Not likely to go away with time please ask your surgeon!an FNAC TEST IS THE BEST WAY TO CONFIRM IT!all the best................... </s>
