my sister has a lump on back left hand side of her head, it doesnt hurt but she has really bad head aches daily for past few months now. she is 32 and 165 cm and weight is 73kg. she has been feeling sick after she eats for the last few months as well. she is a smoker and has only found this lump tonight and is adimit its not been there before. i felt this lump and it is about the size of a 10 cent peice right on the bone part, it is hard but does not move as a cyct would. please any advice on what it could be and if her symptoms could be related to this??
