My dad has a cancerous tumor in his bowel. He was given 5 days of radiation his last treatment was 8 days ago. He is having bloody puss like mucus come out of his rectum several times a day. He is also having cramps and pain. He has had infections in the past that were very similar to what he s experiencing now. Only difference is that he doesn t have a fever at all. In fact he says it s a little low 97.6. He is going to call the doctor first thing Monday morning. It s Saturday now will he be ok to wait that long or should he be doing something about it now?
