Not typically: The blood work in your situation could show anemia, which still requires further tests. A large colon mass or stomach mass could be seen on a study for kidney stone, but it is unlikely. Ct scans are good at looking at parts of the body that are more solid and less tube like. Endoscopy is still better for all of these situation. ...Read more

Could a simple blood test in arm tell if you have stomach or colon cancer?

Could a simple blood test in arm tell if you have stomach or colon cancer?

Depends: A blood count may show anemia than can in turn be traced to a cancer anywhere in the GI tract. Also, if the cancer is advanced, tumor markers or liver enzyme tests may be abnormal. As a rule, blood tests are not good screening methods for cancer, it's mostly luck if they find cancer early. Good question, by the way. ...Read more

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. Now, a ct might suggest a colon cancer, however, colonoscopy is considered the gold standard for detecting colon growths.

I got some white spots on my stomach.This happened after bed tanning.I saw my doctor but she only ran blood test but no results.Can it be skin cancer?

Tanning beds = bad: My first advice for you would be to stop using tanning beds. Using tanning beds before the age of 35 increases your risk of melanoma by 75%. Blood tests are not useful in detecting skin cancers. If the spots remain, the best test is a small skin biopsy. www.roxcancercenter.com. ...Read more

Psible but stil rare: Unclear what the orange mucus is. Blood will sometimes appear orange in stool hemorrhoids, not cancer, would be the most comon cause of blood in the stools but this usually is bright red. You should have an md test for blood in the stool.
