Ladabaum also pointed out that, at a population level, the blood tests will be effective at reducing colorectal cancer deaths only if people who reliably take the test every three years subsequently agree to receive a follow-up colonoscopy if the blood test returns a positive result. ...
One test examines a person's blood for four biomarkers linked to inflammation. In a small study, it outperformed the fecal blood test now used in colon cancer screening, said lead researcher Dr. Mona Eldeeb, of Alexandria University Medical Research Institute in Egypt. ...
To convince more people to undergo the potentially life-saving colonoscopy, Prof. Arber has developed a simple early-warning test that can detect colon cancer in the blood. Using biomarkers, it is the first test on the market that can detect cells of colon polyps –– the precursors to colon...
Surgery is the only curative modality for localized colon cancer (stage I-III). Surgical resection potentially provides the only curative option for patients with limited metastatic disease in liver and/or lung (stage IV disease). Surgical options include the following: Right hemicolectomy: For lesi...

A pair of experimental tests could help doctors detect colon or prostate cancer with just a sample of blood or saliva.
1.) Fecal Occult Blood Test Since polyps and CRCs have a high propensity to bleed, FOBT can detect occult blood.[19] Sample collection: The patient is given a stool collection kit or asked to get one from the pharmacy (as per local protocols) and is asked to bring in stool samples (...
There are many methods for screening for colon cancer. However, the best method is colonoscopy. Nevertheless, the simple classical method as occult blood test is still widely used in clinical practice. Here, the author appraises on colonoscopy with and without occult blood test pre-screening. ...
Many people with colon cancer don't have symptoms. That's why it is so important to keep up with routine screening tests. When the disease -- at any stage -- causes symptoms, they may include: Blood (usually dark red or black) in the stool ...
