Susan, best to take this one step at a time. You noticed the puffiness/mass, and have had it examined, which is good; now you're going to have a biopsy, which may or may not be cancer. FYI, about 85% of biopsies are benign - not cancer. If it's not cancer, the doctors will work to find out what's causing the puffiness and pain, and treat it. If it is cancer — well, then you and your medical team will deal with that, too. You've started down a path whose destination you don't know, at the moment. As time goes by, you'll get a clearer picture of where you're headed. But know that wherever you go, you'll have the strength to handle it. Stay connected here - whatever this mass turns out to be, we can help. Good luck - PJH
