We are still buzzing from the energy at !

Having Jennifer A Douglas - Author + DCIS Patient Advocate, advisor, industry advisory board join us in Seattle is a powerful reminder of why we do what we do. It’s not just about the technology; it’s about the people, the stories, and the commitment to improving every step of the patient journey.

Thank you for sharing your perspective and for being such a vital part of the Perimeter Medical Imaging AI team!

We are honored to have advocate and survivor Jennifer A Douglas - Author + DCIS Patient Advocate share our latest milestone. At Perimeter, we talk a lot about the AI within our Claire™ technology—but for patients like Jennifer, it’s about something much deeper: Confidence.

Our mission with real-time margin assessment is simple:

➡️ For Patients: Aiming to reduce the "waiting game" and the anxiety of potential follow-up surgeries.

➡️ For Surgeons: Providing additional information to assess the margin while the patient is still in the OR.

➡️ For the Future: Advancing the field of surgical oncology by bringing more intraoperative insights to the forefront before the final pathology report.

Thank you, Jennifer, for reminding us of the lives behind the data. We are thrilled to see Claire in the hands of surgeons this year.

Note: The Claire OCT System is an adjunctive tool; it does not replace standard tissue histopathology or provide a diagnosis.

I am thrilled to be sharing that Perimeter has recently received FDA approval for Claire.

Claire is an innovative tool for real-time visualization of excised breast tissue margins.

The Claire AI algorithm is trained on a vast dataset of normal and cancerous breast tissue images to support margin evaluation.

The AI-powered system identifies and marks focal areas suspicious for breast cancer at the margin for surgeon evaluation. This enables surgeons to review these areas while also using standard margin evaluation techniques.

As a longtime DCIS survivor and patient advocate, I am excited about the potential for this technology to support surgeons and their patients!

I am excited to see how Claire benefits patients and surgeons in the coming year.

We are incredibly proud to share a defining milestone for Perimeter!

Perimeter's Claire™ has received premarket approval (PMA) from the FDA. The technology received breakthrough designation from the FDA and is designed to enhance surgeons’ ability to detect cancer during breast-conserving surgery and potentially reduce the need for re-operations.

Claire's approval represents a massive leap forward in our mission to transform the standard of care for breast cancer patients, so that no patient has to be told ‘we didn’t get it all.’

At Perimeter, we believe that including the patient voice ensures that as we develop and advance technology, we're truly grounded in what matters the most: improving the experience and outcomes for those we ultimately serve.

In this short video, Industry Advisory Board member, author, and breast cancer advocate Jennifer A Douglas - Author + DCIS Patient Advocate discusses this crucial topic with our Chair of the Industry Advisory Board, Diana Chan, sharing a powerful insight:

“If we’re not asking what patients are experiencing, then often, that information and those insights get lost.”

Because when we listen, collaborate, and innovate together, we’re always .

Would I need radiation treatment after my lumpectomy? If so, when would I be able to start? Moving on to that next step meant I was that much closer to being done.

My surgery had already been delayed two weeks because of my MRI, and I was anxious to finish my treatment before the new year– not just because I wanted to celebrate without being in the middle of radiation, but because my medical deductible would reset in January.

When I got the call that my margins were clear, I breathed a huge sigh of relief.

After a few weeks of surgical recovery, I was referred to a radiation oncologist to discuss my DCIS and understand why radiation was being recommended. Radiation has been paired with breast-conserving surgery to reduce the risk of recurrence. (https://www.breastcancer.org/treatment/surgery/lumpectomy/plus-radiation)

After a thorough conversation with my radiation oncologist, I made the decision to move forward with it. For me, my age of diagnosis (41) was the primary reason why I was choosing to do radiation.

At the time, I was unaware that there was a biomarker test, called DCISionRT, (https://preludedx.com/dcisionrt/) specifically designed to tell me what my personal benefit from radiation would be. Recent research has shown that this test outperforms clinical pathology in determining the benefit patients receive from radiation. (https://pubmed.ncbi.nlm.nih.gov/40685017/)

My treatment was whole-breast radiation with several additional boosts (increased targeted radiation to my tumor bed) for the last few treatments. I had 20 treatments in total, which spanned over 4 weeks.

Radiation was hard for me and my family. It delayed my recovery significantly, and I experienced extreme fatigue during treatment. Luckily for me, I didn’t have an extra delay due to a second surgery.(https://jenniferadouglas.com/walking-through-cancer-fatigue-during-radiation-treatment/) While I am glad I did radiation, it was a challenging treatment to walk through.

You can read more about how I made my radiation treatment decision here: https://jenniferadouglas.com/dcis-treatment-decisions-radiation/

I’d love to know, did you have radiation treatment after your lumpectomy, and how did you and your team make the decision?

Someone in your life has cancer— now what? How can you support them during (or after) their treatment?

We sat down and asked one of our advisors, Jennifer A Douglas - Writer, breast cancer patient advocate and author, for some ideas. She was diagnosed with DCIS and works in the breast cancer community. She shared this with us:

“I was always touched by the unique ways that the people in my life surrounded us with support. And, it didn’t matter what they did; what mattered was that they were showering me and my family with care during a really difficult time in our lives. Often, what was most difficult for me, as the cancer patient, was saying yes to the support.

Here are a few of the things that made a difference for us during my cancer treatment:
🔹Meals. We all needed to eat, and often, after a long day, the last thing I wanted to do was prepare dinner for my family. We loved getting gift cards to order dinner for delivery, having meals delivered through a meal train, and also enjoying a few deliveries from Spoonful of Comfort. (https://www.spoonfulofcomfort.com/)
🔹 Flowers: These always brightened my day!
🔹 Errand help: We were a busy family with teenage boys, so it really helped when my neighbors and friends could help with grocery runs or give our kids rides to and from their activities.
🔹Rides to and from appointments: I appreciated the friends and neighbors who were able to help out with rides. While I “technically” could have driven to my appointments, it made it less stressful for me when someone drove me there.
🔹 Spontaneous gifts: blankets, cozy socks, puzzles, fun activities, or gift cards for my favorite coffee places.
🔹 Visits: I loved having people stop by for a little while just to say hi. I was tired, but it always made me smile when someone came by.
🔹 Phone calls: It was so nice to know people were thinking of me, and even when I wasn’t up to talking, even a short call brought a smile to my face.
🔹 Practical help: Housecleaning, babysitting, pet sitting, dog walking, laundry, or yard work. These are all things that need to continue, even during treatment. These are often the things that drain our well-being as we try to recover and feel behind.
🔹 Cards: In a world where everything is digital, there is something wonderful about a handwritten note I could put on my bedside and look at. I still have a folder of all the cards I received during treatment.

I was always touched when someone in my life reached out and let me know they were thinking of me."

We hope these ideas inspire you to offer support and encouragement the next time you hear that someone in your life has cancer.
