This really.
My DF has early stage bowel cancer, he said scans show it to be confined and no sign of spread (yet). Chemo (12 week course of it) starting on few days. Hopefully will shrink tumour and allow for successful surgery.
However, DF seems to have been struggling with physical activities recently, things he'd normally enjoy like swimming.
He's not said what's causing the pain but could it be the cancer already making itself felt? Sorry for such questions, this is all new to me and is a lot to learn about.
Could a small and contained tumour cause such discomfort and tiredness at this early stage?
