Hi Emily,
Try to be positive, I've had 3 seperate OC cancers (5 if you count my lymph nodes seperately) and last time around I was initially told my bilateral lymph node tumours (6 in total) were inoperable. After going to the tumour board they decided that a combination of surgery (to reduce the size of the tumours together with radiation & chemo to both sides of my neck may offer me a slim chance - about 10%). Because they re-radiated areas that had already received maximum greys they were reluctant to do this and I had to sign numerous disclaimers.
While I have some significant side effects I have beaten the odds so far. I was told without treatment I would not have seen last Christmas! Although I am going through some tough personal times I am grateful for every extra day!
If she has a 20% chance go for it! I am proof that the odds can be beaten!
Wishing you and your Mom all the best!
Sue
