[|Human|] I am a 47 year old male being treated for anal cancer. I have just had my second round of chemo mitomycin and 5 FU. Have had about 25 external beam radiation treatments. I have a lot of burning around my genitals and now have blisters t the end of my penisn and yellow discharge. It hurts when I pee. What should I do?
[|AI|]  Anal canal cancer is treated by chemotherapy with 5-FU and Antimycin along with external beam radiation therapy. The symptoms you have mentioned are due to side effects of chemo-radiotherapy. You need to have a urine RE (routine examination) test and a course of antibiotics will help. Meanwhile, increase your fluid intake. Cranberry juice will also help in settling the urinary issue. The dark skin and blister can be treated with topical application of steroid, antibiotic and antifungal cream combination. Once the chemo radiotherapy is complete you will be observed for reduction in size of tumor. Normally anal canal cancers keep reducing in size up to 3 months. So your doctor would be examining you with a digital rectal exam with photocopy on monthly basis until complete remission is achieved. Please discuss this with your oncologist.
