I had like a lil like bump filled with puss and blood i squeezed it out it kept coming back the hair wont grow in the spot once i cut it now its like a lil bump on my scalp please help me im scared and not sure what to do?

A scalp subcutaneous mass when repeatedly manipulated released “blood and pus”, just as a sebaceous cyst (which it is, and called a “wen”) would do; is neither cancer nor pre-cancer. The definitive therapy is for the general surgeon to excise it “en bloc” so it never recurs. Leaving it in place allows repeated inflammation & infections. If ignored, over time it grows & becomes cosmetic eyesore.
