well i have had this bean size shape lump on the back of my neck left side for two weeks now i have gone to see my doctor this morning and he is sending me  for an ultrasound and i go today for this...since my sister found a lump on her neck 12 years ago it turned out to be cancer she died a few months later... do i have anything to be worried about????
Hi and welcome to Chat Doctor. You didn't mention what kind of cancer your sister had. You don't have to be concerned, but you should do further test including ultrasound with needle aspiration or biopsy. It is usually only swollen lymph node or subcutaneous benign tumor. After these tests it can be easily surgically removed. Wish you good health.
