could i have secondary bone cancer ?

Only a Dr. can tell you that, but personally, it just sounds like knee problems.

How old are you?

Congrats on your battle with the bowel cancer. My husband died of colon cancer but it was stage 4 when discovered. It sounds like you got it early. Good for you.

Since, at the time of resection, it was determined that your cancer had not metastasized, it seems more reasonable to me to suspect other causes for the joint pain. That being said, it is a sign (especially in the joints), and all cancer has the potential to spread. The best course of action, in my professional opinion, is to talk to your doctor and get some piece of mind.

Thanks for your answers, i am going to see my doc tomorrow as it is a worry. I was lucky to be diagnosed at stage B, i am also only 48 so quite young to have had this. Will keep you posted.
