Suggestion

My mum diagnosed with nose cancer 3rd stage 11/2 yr ago. She had received a radiotheraphy treatment for 30 sections and seems doing well. Recently she got swelling & a lump on neck (with pain) but doctor said should be ok & no medicine was given (from beginning until now). Last 3 weeks mum done a ct scan & informed by doc thru phone outcome was good. We intend to take back all scanning but refer to another check up. This time he told us that the cancer on neck not completly gone & advise to do 3 treatment of chemo follow by radiation. Alternative 10 section of radiation only. (if u got no money) There was no other onchorlogist in my state & I need yr kindness view. Is chemo really effective?TQ. from Malaysia
