LEAD FROM BEHIND is on a mission to make colon cancer famous.
We're raising awareness that is The Preventable Cancer.

► Colon cancer is the second biggest cancer killer in America. 1 in 24 Americans gets colon cancer. It doesn’t need to be - because it’s preventable.
► The best way to prevent colon cancer is by getting a colonoscopy when you turn 45. The guidelines changed in 2021 lowering the age from 50 to 45.
► People don’t want to talk about colonoscopies, let alone get one. We’re using humor and heart to change that.
► Colon cancer is rising in young people - predicted to be the top cancer killer for people under 50 by 2030.

LEAD FROM BEHIND is founded by Brooks Bell, powered by , and created in partnership with Maximum Effort & Chrysi Philalithes.

I made a bet. I lost. But it still paid off. https://leadfrombehind.org/LEAD FROM BEHIND is on a mission to make colon cancer famous. We're raising awareness...
