What if we could stop cancer before it ever starts?

In this episode of From Carpools to Chemo, host Marisa Peters sits down with Dr. Heinz-Josef Lenz, Deputy Director for Research Programs at the USC Norris Comprehensive Cancer Center and one of the world’s leading experts in gastrointestinal cancer.

With more than 30 years of experience in colorectal cancer research, Dr. Lenz has helped transform how we understand and treat cancer through his “clinic-to-bench” approach. His work on molecular subtypes like MSI-high and BRAF mutations has opened new possibilities for patients facing colorectal cancer.

Beyond science, Dr. Lenz reflects on mentorship, teamwork, patient advocacy, and the lessons he has learned from thousands of patients. Ahead of the second annual Be Seen Alive Awards, this conversation explores how trust, collaboration, and innovation are shaping the future of cancer treatment.

Key Takeaways

• A father’s illness inspired Dr. Lenz’s path into medicine.
• Patients are partners in their own care journey.
• A negative trial can still create meaningful breakthroughs.
• Molecular research is changing cancer treatment.
• MSI-high discoveries have improved outcomes for many patients.
• Cancer prevention may be the next frontier.
• RNA, methylation, and epigenetics could unlock future advances.

What happens after the last cancer treatment, when everyone assumes the patient is finally okay? In this episode of From Carpools to Chemo, Marisa Peters speaks with actress, advocate, stage IV colon cancer survivor, and Alive Awards honoree Elizabeth Wachsberg. Diagnosed at 38 after a colon blockage sent her to the ER, Elizabeth faced chemotherapy, surgery, panic attacks, and the struggle to keep her health insurance while fighting for her life, until a surgeon gave her hope with the words, “Let’s cure this thing.”

Elizabeth opens up about why “warrior” language can feel like a trap, and the grief of surviving when so many others do not. She also shares how humor helped her through the darkest moments and why support must continue after treatment ends. Her story is a powerful reminder that the last treatment does not mark the end of the journey or the need for care.

In this episode of From Carpools to Chemo, host Marisa Peters sits down with JJ Singleton, a 27-year-old former college football player whose life took a devastating turn when a throbbing in his abdomen turned out to be colorectal cancer. Now 10 years into his journey, JJ has endured 10 surgeries, 4 failed chemo cocktails, 450 days without food or water, and is approaching his 173rd round of treatment. And he's still standing, unfiltered, unpolished, and more real than ever.

JJ takes us back to Memorial Day 2015, when he first felt the pain. As a former athlete, he did what athletes do: he pushed through. He ignored the blood in his stool, ignored the weight loss, which he mistook for fitness progress, and kept training for a CrossFit competition. But by the time his mom convinced him to see a doctor, the tumor was so large you could see it pulsing through his shirt.

What followed was a decade of misdiagnoses, failed treatments, clinical trial "Hail Marys," and a body that betrayed him. But it was also a decade of unlikely friendship, radical honesty, and an advocacy journey that started on a bathroom floor, covered in vomit, watching polished cancer commercials, and vowing that if he ever shared his story, it would be 100% real.

Tune in to hear JJ's extraordinary story of resilience, realness, and the power of saying yes. Whether you're navigating your own diagnosis, supporting a loved one, or simply need a reminder that you're not alone, this conversation is for you. Listen now and discover what it truly means to be seen.

What if one simple test could give you more time?

In this episode of From Carpools to Chemo, Marisa Peters sits down with Dr. Jordan Karlitz, nationally recognized gastroenterologist and Senior Medical Officer at Exact Sciences, to break down one of the most urgent public health issues today: colorectal cancer.

Despite being one of the most preventable cancers, millions of people are still skipping screening, and the consequences are rising fast, especially in younger adults.

Dr. Karlitz shares what’s really happening behind the data, why screening guidelines changed, and how new non-invasive technologies are making early detection more accessible than ever.

But this conversation goes beyond medicine. It’s about advocacy, awareness, and the life-saving power of speaking up before it’s too late.

If you’ve ever delayed a checkup, ignored symptoms, or assumed “it won’t happen to me,” this episode is your wake-up call.

Key Takeaways

• Colorectal cancer is the #2 cancer killer but is highly preventable with early screening
• Screening should begin at age 45 for average-risk individuals
• Millions remain unscreened, largely due to fear, stigma, and lack of awareness
• Non-invasive tests are increasing access and improving adherence
• Being proactive and advocating for your own health can change outcomes
• Get clarity on colonoscopy vs non-invasive screening options
• Hear a powerful reminder of why early detection literally buys time

Imagine knowing you should schedule a preventive screening but putting it off because navigating the healthcare system feels overwhelming.

In this episode of From Carpools to Chemo on The BE SEEN Network, host Marisa Peters speaks with Alex Colavin, co-founder of Threshold Health, about the barriers that prevent people from accessing life-saving cancer screenings. From complicated scheduling systems to psychological avoidance, many people delay care until symptoms become severe.

Alex shares his journey from studying cancer evolution as a scientist to building a company focused on improving access to preventive care. Through Threshold Health’s Beeline service, patients are connected with human care navigators who help simplify the process of scheduling screenings and taking the next step toward early detection. Because we know when scheduling is made easier - more people are seen.

Together, Marisa and Alex discuss why prevention should be easier, how small system changes can dramatically increase screening rates, and why making healthcare more human may be the key to saving lives.
