ALBANY, N.Y. -- Driving around the Capital Region this month, you may see things in a new light - a blue light.

March is Colorectal Cancer Awareness Month. To get the word out about the importance of early detection, Albany, Troy, and Schenectady main streets will be lit up in blue.

Several locations are offering free colon cancer screenings, including the CDTA bus station.

As part of a state-funded program, anyone over the age of 50 who is uninsured or underinsured is eligible for free screenings.

One man we spoke to knows first hand that those free screenings can save lives.

"In my case, I had a colonoscopy, they found two polyps which are pre-cancerous. The cancer comes from the polyps. They found them, cut them out, and that's it," said American Cancer Society volunteer Sam Petrecky.

The American Cancer Society says if everyone over 50 was tested for colon cancer, it could save 25,000 people a year.
