8438884599_dd69d0f44eThe number of people diagnosed with cancer every year is alarming, but chances of surviving this horrible disease can all depend on checkups.  A study published Friday in the Journal of Molecular Diagnostics suggests that a blood test for colon cancer could be on the horizon.

The lifetime risk of developing colorectal cancer is 1 in 20, and men are slightly more likely to get it than women, according to the In 2013, it is expected to cause more than 50,000 deaths.   The study compared tumor tissue samples from patients to non-tumor tissue, and identified candidate genes that could be markers for colon cancer. They focused on one for further investigation, a marker called SDC2.

Scientists took blood samples from 12 cancer patients with different stages of cancer and looked for a gene.  They found the gene was present and detected, in the patient’s blood.  It is unknown if this particular test can be used to detect cancer early enough to save lives and prevent people from developing this disease.  More research needs to be done .
