I can only comment on my cancer which is the same secoundary bone cancer from lung cancer i was given 12 months without treatment and 18 with that said i had the chemo

only for my families sake it was a long hard winter last year for me.ive had 3x 3 month cat scans and my cancer is stable not doing anything i live life day to day happy i guess and long may it last the mind needs stimulating tinker with things of interest cars computers whatever light exercise very light if you fracture a bone it cant be repaired.i have the biggest concentration in the pelvis it made a hole in my upper right fema i have 2 deposits in my neck and in my right colar bone and shoulder i sleep and rest when my body tells me too and i just enjoy doing whatever takes my fancy that day that could eevn be to read a book .i hope your dad manages a happy routine that keeps him smileing and dont worry about time no one knows they are just best guesses.even my oncologist said ive told paitents 12 months and 4 years later he,s still seeing them good luck and chin up all my love and best wishes to your dad and family.

i reconise that i watch old on the busses and open all hours on you tube its just a bit of escapism i sleep a as and when but ive started getting out just to the local suppermartket for half an hour and im pushing myself to do stuff each day it makes me feel better and gives me a bit of purpose i hope he picks up a bit for you.
