Advances in molecular diagnostics are reshaping how cancer is detected, monitored, and treated, and liquid biopsy is becoming central to that progress. This simple blood draw can reveal key tumor biology at diagnosis and over time, providing timely insight and guiding more precise decisions throughout a patient’s journey. Clinicians now face an important challenge: knowing what is actionable today and what is coming next so more patients can benefit from the promise of these advances.

As we kick off Season 7, host and patient advocate Karan Cushman expands this season’s focus on Bringing Precision Medicine to Everyone with a deeper look inside the science of liquid biopsy. The conversation features two leaders shaping the field: Dr. Christian Rolfo, Division Director of Medical Oncology at The James Comprehensive Cancer Center at Ohio State University, and Dr. Roberto Borea, Medical Oncologist and emerging investigator from the Rolfo Lab.

Together, they break down the scientific momentum driving liquid biopsy forward, including tumor fraction, MRD-guided treatment strategies, resistance monitoring, fragmentomics, and the expanding frontier of early detection. They also discuss the barriers that continue to slow broader adoption, such as assay variability, limited standardization, reimbursement gaps, and operational challenges in community settings.

In this episode, we cover:

• How tumor fraction is emerging as a meaningful real-time biomarker

• Where MRD-driven escalation and de-escalation strategies are heading

• The current promise and limitations of early detection and MCED testing

• What is required to standardize liquid biopsy across reporting, workflows, and clinical trials

Episode 70 offers a clear look at the advances researchers are helping drive right now and what these developments could mean for clinicians, laboratories, and patients in the near future.

This conversation builds on episode 69 with Dr. Kashyap Patel, who introduced the foundations of liquid biopsy and its role in accelerating treatment decisions. Combined, these two episodes offer clinicians and patients an overview of where the science and real-world applications stand now and where the field is headed next.

Liquid biopsy is breaking speed and access barriers in precision oncology. In this episode of the Precision Medicine Podcast, part of our series Bringing Precision Medicine to Everyone and the first in a two-part focus, founder and host Karan Cushman speaks with Dr. Kashyap Patel, CEO of Carolina Blood and Cancer Care Associates, author, and national leader in value-based oncology.

Together, they explore how liquid biopsy is changing the diagnostic and treatment landscape. This blood-based test can deliver results in days, be repeated as needed, and reduce the need for invasive procedures. Tissue biopsy remains important, but when the samples are too small or unsuitable for testing, liquid biopsy provides a valuable alternative in guiding treatment decisions and monitoring disease.

For patients with aggressive “turbo cancers” such as diffuse large B-cell lymphoma or small cell lung cancer, the time saved can be lifesaving. Karan shares her own experience with DLBCL, while Dr. Patel highlights real-world cases where liquid biopsy revealed actionable mutations, informed therapy, or enabled minimal residual disease (MRD) monitoring.

Finally, Dr. Patel underscores the need for standardization and payer alignment to move liquid biopsy from innovation to everyday practice. This candid discussion frames liquid biopsy not as a futuristic idea, but as a clinically powerful and scalable tool that is closing gaps in precision oncology today.

What does it really mean to bring precision medicine to every patient, in every community?

In this inspiring, one-hour episode of the Precision Medicine Podcast, host Karan Cushman sits down with Dr. Arif Kamal, Chief Patient Officer at the American Cancer Society (ACS), for a wide-ranging conversation that reframes how we think about progress in cancer care. With a background in oncology, palliative care and health system innovation—and a personal story shaped by his mother’s metastatic breast cancer diagnosis—Dr. Kamal offers a deeply human perspective on what it means to deliver not just the right treatment, but the right experience for every patient.

Dr. Kamal shares how the ACS is working to make precision medicine more equitable by addressing barriers like geography, affordability, clinician burnout, and fragmented care. He explains the importance of “precision compassion”—the idea that personalized care must also include empathy, listening, and action tailored to the needs of each individual. “We can’t talk about innovation,” he says, “without talking about accessibility.”

From the importance of whole-person care and mobile health units in rural communities, to expanding insurance coverage for biomarker testing and building trust with patients and caregivers, this conversation is full of insight into what it will truly take to change the odds for people facing cancer.

You’ll also hear about the ACS’s bold initiatives:

• The Change the Odds campaign, tackling ZIP code-driven disparities in care
• ACS CAN’s legislative efforts to expand access to biomarker testing
• How the ACS’s roundtables and grassroots partnerships support health systems, clinicians, and researchers nationwide

Dr. Kamal challenges us to think beyond science alone and focus on what really matters to patients—whether that’s more time, better quality of life or simply the ability to hold a grandchild on the beach.

Don’t miss this conversation about how we turn precision medicine from a possibility into a promise—one rooted in empathy, equity and action.
