Hi all,

I'm new to this group but I was hoping you could help me out if anyone knows more about chemotherapy than I do. My dad (in his mid 50s) was diagnosed with colorectal cancer in December. At first he was optimistic and thought it was the early stages, then we found out it was Stage III and after surgery before chemo we found out it had spread to his bones.

After surgery he had an infection and wasn't able to start chemo when he was meant to. Finally they checked him in and put him on an antibiotic drip (oral antibiotics hadn't worked.) He started chemo and apparently it was working well but I just found out they changed his chemo drug about 3 weeks ago because he developed resistance.

I don't know much about this and I can't speak to the doctors because I am on my year abroad studying modern languages. I don't think my family is that honest with me, or even the doctors (they like to be optimistic, they say it is better for recovery). I don't know if I should be worried about this resistance. I read that if you're resistant to one drug you're more likely to be resistant to more. But I couldn't find that much information about it.

I know that bone metastasis means it is a very advanced stage (I had to find that out myself though - is it terminal??) but my dad looks completely fine and I feel very confused about whether I should be worried and how long I should expect him to live.

If anyone can tell me more I would be so thankful! I've been feeling very confused and I have to make a lot of choices right now
