hey there, i have a problem, from about 5 weeks i have had a pea sized lump in my groin , it doesnt really hurt much, it was only painful for 3 first day then it stopped, i also have been extremly tired all the time and i could sleep all days long, i have experienced severe headaches too, now i started to develop a white lump in my throat . What could it be? Is there a chance it could be cancer?
