My dearest friend was diagnosed with Stage 3 (t4?) colon cancer a few months ago.

he is 72 but in pretty good health other than the tumour. 
 

He had surgery and it was removed.  There was nothing need for a stoma and other than understandable aches and pains due to healing (keyhole surgery), he feels okay.  Oh but did say that having a poo is a different experience now, due to some of his rectum being removed too.

He had his follow up appointment with the surgeon, to discuss the lab results and way forward.   
Surgeon said that he removed everything but that due to the type of cancer he had (can't remember the name of it), chemotherapy would not be appropriate as it doesn't work for his type.

He has a three month follow up.

I'm confused.  I had thought it was the protocol to giv chemotherapy as a prophylactic treatment.

wish I could remember the type of malignancy he had. 
 

Can anyone help fill the gaps please?
