Anybody tell me what happens when you have been having treatment on and off for 4 years. I am still on chemo, but my count this week has risen to 617, so obvioulsy something is happening. How do I know if the cancer has spread elsewhere? This is the 5th different drug I've been on, how long can I carry on like this? I know all the new people are worried, but I'm not wondering what happens next! Anybody help me out?
