A member asked:
Does a intestinal or colon cancer show in a blood test thru the wbc ? and if there is no bleeding is it possible to be cancer?

NO AND YES: Not all cancers bleed, and elevated or low WBC count is not specific for colon cancer. If undiagnosed, it will obstruct the flow of fecal material and or bleed, once it gets to a larger size.

Then it is too late: Early intestinal and colon cancers ( GI ) are asymtamatic, WBC not useful , tumor markers like CEA is mostly used for follow up for a recurrence of disease. Besides awareness only way for early detection is visit to your doctor, stool for occult blood, and endoscopy to achive the cure.

No and yes: There is a blood test that we use in colon cancer, however it is not advised for screening. There can be colon cancer without bleeding. Only 25% of colon cancers present with bleeding.
