Influencer Shay Martin is spreading awareness about colorectal cancer after the death of her husband, Tanner Martin. In an exclusive interview with Us Weekly, Shay opened up about why she decided to urge her mom to undergo a screening months after Tanner announced his own death at age 30 following a five-year battle with stage 4 colon cancer. "My mom watched me take care of my dying husband for five years, so she has always been super aware of screening and its importance," Shay told Us.
