hi. my dad has stage 4 throat cancer.it has several sites in the mouth and throat. it hit all the lymph nodes above the neck.he went thru the chemo and radiation together.well they did his pet scan last week. the dr called and said that the main tumor has shrunk ,but is still lit up showing cancer cells are present.it has not spread anywhere else. i guess my question is since its still active and they did the most drastic treatment,is this it? is he going to die from this horrible disease. i know my mom reads these so mom if you read this dont be mad! the doctor told us if this didn't work then we at least bought him some time. i am so angry right now. i guess i never really dealt with the thought that my dad could die from this.i just kept thinking he can beat this thing. i guess i just never expected my dad(my superhero) would be taken by this.thank you guys so much for letting me vent all this.its been a really rough day.....
