Hi ! The mass itself you have described signifies that there is an abnormal growth from any of the intra-abdominal organs in your body. As it is noted by you for the last one year, let us presume that possibly it is a benign lesion. However, to be sure and to exclude any thing otherwise, it has to be investigated with advanced radiological modalities ( ultrasound
, CT scan
if need be ) after being clinically examined by a surgeon. If on investigations, it comes out to be a pelvic mass from the reproductive organs, then you may have to consult a gynaecologist for further management.
Whatever the management comes out to be, it is better be done at the earliest so that you can have better recovery and prognosis. So consult your doctor/family physician/surgeon at the earliest. Take care and good luck.
