Study supports genetic testing for colorectal cancer: 4 key notes

A study conducted at Boston-based Dana-Farber Cancer Institute examined the role of genetic testing for inherited risk of colorectal cancer, Targeted Oncology reports.

Here's what you should know:

1. Researchers analyzed 1,058 individuals with colon cancer.

2. The patients agreed to have blood drawn for research.

3. Researchers performed germline testing on all individuals using a 25-gene panel to look for inherited mutations associated with cancer risk.

4. Researchers found that inherited mutations were identified in nearly 10 percent of individuals analyzed with the 25-gene panel.

Researchers said that number "was higher than what we would have expected in the past."

The researchers concluded that there might be a link between mutations in those genes and CRC risk.
