Wouldnt a blood test or cat scan show stomach or colon cancer.?

Wouldnt a blood test or cat scan show stomach or colon cancer.?

Not if early: A ct is not sensitive enough to find very small colon growths. There is a blood test the cea that is high in some cancers, but usually only when quite advanced and not specific to colon cancer.

It does depend on size and depth of the tumor, if it has spread to lymph nodes or other places and genetics of the cancer itself. Some patients have very advanced tumors with no symptoms while some have symptoms and have a very curable cancer. ...Read more

Can KUB show polyps and/or colon cancer?

Can KUB show polyps and/or colon cancer?

Not usually: Polyps and Colin cancer are soft tissue conditions, and do do not typically show up on X-ray. The main exceptions to this are if they are calcified, if they are causing a bowel obstruction ( you can diagnose the obstruction but not the cancer), or if contrast is given in the GI tract first ( known as a upper or lower GI series). Ct scan is the radiologic test of choice, colonoscopy shows as wel ...Read more

If someone got colon cancer and never got treatment of any sort, how long before they would show signs of being sick and how long would they live for?

If someone got colon cancer and never got treatment of any sort, how long before they would show signs of being sick and how long would they live for?

A long time,,: This disease takes a while to develop like 20-30 years, unless it's associated with one of the polyp syndromes that cause it to appear much earlier. Usually it presents in the sixth decade of life (50-60) as fatigue and or change in bowel habits and abdominal discomfort. By this time it's usually advanced and 5 year survival is compromised. That's why colonoscopy is done for polyps at 50. ...Read more

3 cycles of chemotherapy so far for metastic colon cancer shows therapy working , if 2 cycles are missed due to ill health , will cancer start growing agsin ?

No: If 3 cycles of chemo given and well tolerated, evaluation might show stability or regression if drugs working. If missing 2 cycles, this will not allow further regression while off medication, but if resumed a further response may be defined. Most combo drugs for colon cancer may show a termporary response but not cure. The newer combinations with Immunochemotherapy more effective. ...Read more
