Tamara Shaw lost a wife, daughter and twin sister, respectively, when Tiffany Oritz died of colon cancer last year. The Jacksonville residents will be among the 24 people featured in "No Excuses," a national colorectal cancer awareness campaign launching in March in New York's Times Square. Their stories will also be featured on Fight Colorectal Cancer's Facebook page. They are dedicating a year of volunteer time to raise awareness of the importance of screening, using their personal stories in an effort to help save lives. Colon and rectal cancers make up the second-leading cause of cancer deaths in the country among men and women combined, the organization said. Sixty percent of colorectal cancer deaths could be prevented with screening.
