My mother has been taking fortwin injections almost weekly since last 20 years. She was suffering from breast cancer which has been operated upon and doctors have given clearence after kemo. its been almost 5 yrs now. since last 3 months she had some boil in the general area where she used to be injected fortwin. this boil became bad and got converted to 1/2 inch hole from where pus ozes out. Doctors adviced us to keep on doing dressing till the pus dries. but now another such hole has emerged and they are suggesting multiple surgeries with plastic surgery. which her body cant take. moreover the injections are still continuing. kindly guide
