Patient reported long-term side effects from treatment on urinary and sexual function in anal cancer survivors - 3- and 6-year results from the Swedish national ANCA study.

For anal cancer survivors, urinary function was impaired after 3 years and continued to deteriorate as measured at 6 years after diagnosis. Anal cancer and its treatment negatively affected sexual function for both men and women. This may explain why patients reported that sexual activity and frequency of intercourse was not of importance in their life.
