Our Accelerated Diagnosis service is a new approach to cancer diagnosis. We help people who have symptoms or abnormal screening results for breast cancer get clear answers faster, through high-quality, expedited diagnostic services, with the support you need.

We offer same-day or next-day virtual appointments. No waiting weeks just to get started.

Defiant currently offers services in Massachusetts, with other locations coming soon.

No referral is needed. You can book directly with our doctors.

Yes, Defiant can work with your current primary care doctor or other specialists (such as a gynecologist) to help coordinate your care throughout the process. If you don’t have a primary care doctor, we can still help you.

We refer to high-quality imaging centers near you. We’ll handle scheduling and coordination.

We expedite your imaging—typically within days, not weeks. We'll coordinate everything, including getting your prior images and records if you have any, and help cut through the delays.

In some cases, an ultrasound-guided biopsy can be offered to Defiant Health patients on the same day as the diagnostic mammogram and ultrasound. However, there are certain situations where it may not be clinically appropriate to do the biopsy on the same day or certain partners that cannot offer same-day biopsy. Defiant works very closely with our radiology partners to minimize the time it takes to schedule the biopsy so that you don’t have to wait for weeks to get answers.

We’ll help you take the next steps quickly: a jump-start on additional testing based on Dana-Farber Cancer Institute protocols, referrals to top oncologists based on your specific diagnosis and needs, and a clear plan for how to prepare for treatment.

Absolutely. We’ll break everything down in plain language, and we’re available to answer questions every step of the way.

Yes. We can help you understand how to make the decisions about where to seek care, and guide you through your options. And we will take care of the referral.

Dana-Farber partnered in founding Defiant because Dana-Farber believes that all patients deserve timely access to expert diagnosis. Dana-Farber powers Defiant through access to best practices and clinical protocols that inform Defiant’s diagnostic process.

All imaging and labs ordered by your Defiant Health clinician will be billed directly to your insurance by our partners.

Defiant Health is unable to offer some services to HMO health plans. If you’re unsure whether your insurance plan is accepted, reach out to us at support@defianthealth.com.

We work with self-pay patients and can help find the most cost-effective options for imaging and follow-up care, which will be out-of-pocket and in addition to the Defiant Health fee.

Yes, the diagnostic service offered by Defiant Health is considered an eligible medical expense that can be paid for using FSA and HSA dollars.

No. Imaging and testing are billed separately, usually through your insurance. We work with your providers to make sure you’re only getting what’s needed—and that it's as seamless as possible.
