March is Colorectal Cancer Awareness Month, and doctors say screenings are critical. Cases in adults under 55 are going up.A new Optum KC Wellness on Wheels mobile unit is making screening easy. "It makes it easier for people to come in and get their care," Optum Senior Medical Director Dr. David Nill said. The group is hitting 39 area counties over the next year. They say colon cancer is the third-highest cancer-related cause of death. "The numbers are staggering, that it's gone from 11% about 30 years ago to 20% of cancers in people less than 55 years of age," Nill said. The doctor says there are a couple of causes for the new cases in younger people."It could be diet related. It could be related to alcohol, any number of things," Nill said. The doctor says the big issue right now is that 40% of those younger adults who were scheduled to get exams before COVID-19 didn’t get them during the pandemic and still haven't."They're seeing it earlier, so that's why they moved the recommendation from age 50 down to age 45," Nill said.He also says it’s never been easier to get screened. "Colonoscopy has always been the gold standard. Now you have these kits. They ship it to your house, you do the collection at your house, and UPS picks it up and sends it off and gets it analyzed,” Nill said. “If you catch it early, you can cure it, but if you wait too long, you can't."The group currently has four trucks but hopes to expand to six.You can go to their website for more information about where the trucks will be.
