I have had a prickly jabbing pain in the area of my anus for about 3 weeks or so, I have also had difficult bowel movements and prickly pain like trying to pass a cockle burr or something. My fesis is sometimes dark and stiff, but generally fairly soft and brown. I have been to my urologist and had a biopsy done recently and he has told me that I have early stage prostate cancer. Any idea what else might be going on here?
