Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
Let me start by reassuring you, that this is in no way suggestive of cancer.
UTI in males is extremely complicated, and can take up to a month to heal. The peri-anal itching you have is not related to UTI, and since it is occuring after BM, it mostly points towards some chemicals in the food which is not getting digested and is irritating the tract in the process of passing out. Steroid ointment is the first line of treatment. So give ita few more days, and the irritation and itching should come down by then. If not you need to get the area examined and start treatment accordingly. You may need a stool examination done too.
However once again, this is no way suggestive of cancer. So please do not worry.
Regards.
