Defiant gets you answers in days, not months — with the right plan, the right doctors, and Dana-Farber behind every step.
What defiant does
We get you to the best cancer care in the country — in days, right where you live.
FAST
We move fast
Most cancer diagnoses take 3–4 months from first suspicious finding to first treatment. Defiant gets you there in days — up to 90% faster, without skipping a step.
RIGHT
We get it right
Our clinicians use diagnostic and treatment-planning tools built by Dana-Farber Cancer Institute — Harvard's cancer hospital, ranked top 3 in the U.S. for 25 years running.
BEST
We find you the best doctor, close to home
Sometimes the best cancer care is close to home. Sometimes you need a world expert. We help you tell the difference — and make the right call for you and your family.
HOW IT WORKS
Three steps between worry and a plan you can trust.
We work alongside your care team—supporting you in the moments in between visits. We don’t replace your doctors. Instead, we help patients get:
1
Quality, accelerated diagnostic testing
Most cancer diagnoses take 3–4 months from first suspicious finding to first treatment. Defiant gets you there in days — up to 90% faster, without skipping a step.
2
Expert referral to the best doctor, close to home
An expedited appointment, arranged oncologist-to-oncologist — with your tests ordered at the visit, not weeks after it.
3
Dana-Farber care plan review
Before treatment begins, your care plan is reviewed against the standards of one of the world's leading cancer centers.
HOW WE HELP
Every patient. Every step. Most cancers.
Clarity when it’s hardest
We translate scans, results, and pathology into plain English so you know what's happening and what comes next.
Faster movement through care
We coordinate imaging, biopsies, and specialist appointments so you're not stuck waiting or chasing the system.
The right doctor for you
Sometimes the best care is close to home. Sometimes you need a world expert. We help you tell the difference — and make the right call for you and your family.
Expert navigation, powered by Dana-Farber
Most people go through cancer once. We do it every day — using diagnostic and treatment-planning tools built by Harvard's cancer hospital.
Through every step
Walk into every appointment informed and confident. Between appointments, we stay with you through the waiting and uncertainty — you don't carry it alone.
Harvard-quality care, from a doctor close to home
We support your existing care team during the most anxious window of your life. We don't replace them.
