Hi there, My mother has just noticed a small and hardly noticeable lump on her forehead . From a long range we could not find this lump and it barely changes the appearance of the shape of her forehead, but concentrating on the forehead closely we could notice an ever so tiny lump of some sort. My mother is worried this is a sign of Leukaemia. Could this be or is it just a bump that could have arisen from anywhere and would it need an appointment with a GP or oncologist of some sort? Thanks!
