Newbie Cathy here. Just strolling around trying to get my feet back under me. Had my first colonoscopy 3 years ago at which time they found and removed two benign polyps. Turns out they missed one the first time, thank goodness, because by the time it was caught when I went in for my 3-year re-check, it had turned into cancer. Because of that, I had a pelvic CT scan, an abdomen CT scans and a chest x-ray. Thank goodness for the chest x-ray because they found a 3.3 cm tumor in my upper right lung. A needle biopsy was performed, it was malignant but it was a second primary, NOT metastasized from the colon cancer! Because of having two primaries present, a PET scan was performed and no other surprises were found. I underwent a lobectomy on Sept. 30. Because I am "relatively young" (54), it was recommended - and I chose - to go through 4 rounds of chemo with Cisplatin and Alimta. My first session was Nov. 1. I developed a nasty headache that night and because I have an aneurysm titanium coil from 2000 in my brain, the doctor decided to pull me in for an MRI just to make sure the coil was safe and sound. Thank goodness for my aneurysm history. because the MRI had found a brain tumor, probably metastasize from the lung tumor! The chemo has been put on hold and I am now undergoing 20 rounds of whole-head radiation. The original colo-rectal cancer has yet to be dealt with but the doctors are pretty sure it all came out with the polyp but want to do a surrounding tissue excision at some point in the future. Obviously, that has become a way back-burner issue for now. So there. I've introduced myself.
