Summary

Introduction

Colon and rectum cancer is the third of all cancers by its incidence. It is in second place by the mortality caused by cancer. Colorectal cancer is the most frequent type of cancer after breast cancer and ovarian cancer in women and lung cancer in male [1]. At least 60% of patients with rectal cancer can expect long-term survival after multi-modal treatment. About 80% of male patients were sexually active at the time of di-agnosis of rectal cancer, but often develop sexual dysfunction [2]. Radiotherapy treatment is recommended for patients to improve local control of the disease [3,4]. Sexual dysfunction often occurs after external radiotherapy [5,6]
