What is pelvic lymphadenopathies?

I had TAHBSO last year because I got a endometrial cancer and after a month the doctor advised me to have a CT scan to make sure everything is clear. The result was negative. Just this week I had my whole abdomen CT scan again just a yearly check up of any abnormalities inside. Indeed, it was found out that there are at least 2 recent nodular densities representing enlarged lymph nodes in the left pelvic side walls, level of the cervical stump, measuring up to 0.6cm and 0.7cm in widest diameter. My doctor said I need to have a chemotherapy to get rid of it. Is it the proper way to do it?
