The Health Battle: Courage and Community Support
Koller’s health journey began in June 2024 when he was diagnosed with adenocarcinoma of the esophagus, a form of cancer that starts in gland cells . The diagnosis forced Sick Of It All to cancel their planned European tour and pause all band activities while he underwent treatment .
After months of chemotherapy, Koller shared a hopeful milestone in May 2025, announcing in a video message: “I’ve got some good news for everyone. I got my test results back. And it turns out, it looks like there’s nothing left. No more cancer. So I’m officially cancer-free right now. Thank God for that” .
However, the cancer returned just four months later. In September 2025, Koller posted a video message revealing the setback: “Unfortunately the cancer has come back, and he’s brought some friends with him. I was having a really hard time with my recovery. I was having a tough time gaining weight and keeping food down, so I had some scans done and sure enough, he’s back” .
The physical toll was devastating. According to his brother Pete Koller, Lou lost approximately 70 pounds during his fight, dropping from 190 pounds to just 119 pounds at one point . He required a feeding tube and round-the-clock care from family members, including his brother Matt and sister-in-law Connie, who served as his primary caregivers .
