We guide you from “What now?” to “Here’s what to do next.”
You shouldn’t have to wait weeks to talk to someone who can help you, not give generalized advice. And you shouldn’t be buried under phone calls and paperwork when you are under stress.
With Defiant, you get:
We connect you with our physicians who focus on helping women facing a breast cancer diagnosis—often within 24 hours—so you can start getting clarity now.
From surgeons to oncologists, we match you with top local specialists based on your diagnosis, clinical stage, hormone receptor status, HER2 status, preferences, and insurance—so you're surrounded by the right people from the start.
We’ll use our expertise—and your specific diagnosis—to coordinate concurrent appointments with surgical oncology, medical oncology, and plastic surgery (if needed), so you don’t face needless delays. We also handle the paperwork and scheduling, so you don’t have to.
We know that getting treatment started as soon as possible is vital, so our doctors utilize the time before you even meet with your oncology team to get you started on the necessary staging imaging and labs your oncologist will need — following Dana-Farber Cancer Institute's diagnostic expertise.
Our doctors and care coordinators don’t just give you facts—they walk with you through the emotions, the appointments, the decisions. You don’t have to figure this out alone.
If you're confused by test results, treatment plans, or next steps, we explain everything in plain language and help you feel confident in your care decisions.
We can also connect you with the right specialists for a trusted second opinion—without the stress of chasing records or paperwork.
