Hi I Was Diagnosed With A Brain Mass Or Cerebellar

Hi I was diagnosed with a brain mass or cerebellar and dc said I have it this undiagnosed mass since 2015 showed up on my other pics. I had MRI and ct contrast and 2 ultrasounds all for the back of my neck and 3 more for a benign tumor in front. The surgical area was just opened but the cyst was not removed discovered after 4 pics one MRA on brain. So the bone and joint said too much for him. Now I am going to vascular surgeon. I did have one neuro say I had a soft tissue in 9/21/2016 and the general surgeon said at the ultrasound he was there- is no cyst just ligament. So am I to assume all these tests and someone should of got that soft cell now it has an aneurysm.
