Hi,
a recent hip MRI showed an incendental finding of a 4.2 cm cystic mass in the rectosigmoid region, which my new Gastroenterologist (referred for other things) said with a concerned tone of voice, is very unusual (in that area). I have had 5 pelvic ultrasounds in my life, the last one about 10 months ago, and they have never found a mass there... So it concerns me, as I've also read that nearly all cystic like masses in that region are there at birth (duplication cysts).
I've been referred for a rectal MRI (have not got the date yet), and it's only when I spoke to the Gastroenterologist and heard/felt her concern about it, that I started to get really worried about it! I'm trying not to get too ahead of things, the main thing that concerns me if it was cancer is the treatment, as I don't know if my body can handle it as I have chronic illnesses. But I want to be positive whatever happens!
