Hi, let us hope for the best, It is the metastasis of the cancer cells, to the rectum, and there is every possibility of further spread. But time will solve your problem, The present treatment may be sufficient for the present, when ever you get exacerbation of the symptoms you consult your doctor for treatment.  Avoid taking spices, junk foods, and oily foods. Thank you.
