I had a colon cancer mass that was completely blocking my colon, surgically removed in January 2024 -- stage IIA, clear margins, 40 lymph nodes removed, all of which tested negative. I've had no history of any cancer prior to that time. Based in part on my first Signatera evaluation, which came back 0.0, I did not receive chemo or radiation. Reversal surgery for my ostomy bag was done in May, 2024. CT scans done in March, 2024 showed no lesions in any organ in my abdomen. My second Signatera test just came back negative -- 0.0 -- yesterday, June 24, 2024. These test results coincided with my CT scan also done last week, which showed four cancerous tumors in my liver which had not been there in the March CT scan. My oncologist has ordered a biopsy this week. He was rather stunned that this had occurred ... needless to say, so am I.
