A 68 year old male relative of mine has recently had endoscopy after a positive result from a screening test (his first one)
The endoscopy resulted in the removal of 5 polyps but one 40mm one was too large to deal with. The biopsy from which came back a cancerous, the next step is a CT scan to try and stage the cancer. He had a ct scan 18 months ago for a stomach ulcer, this scan has now been reviewed and shows no signs of other organ tumours, my question is 18 months enough time to get to stage 4 from a previously clear CT scan. In other words how fast does cancer actually spread.
