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.

Dr. Vaillaplana has given you a succinct, accurate answer and I want to reinforce the importance of getting a proper diagnosis. If you are concerned that you have intestinal cancer, this alone is enough reason for a proper check by a scientific physician. Be brave, and get it done, and we will all hope for the best -- either no cancer, or the likely early-found lesion that is then cured.

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.
