For the first time, cancer
is making itself useful.

Introducing a breakthrough way to treat cancer.

RefleXion’s biology-guided radiotherapy (BgRT) allows us to detect and respond to signals emitted from the cancer itself, and for the first time, use them to guide immediate treatment.

Real-Time Guidance

Cancer is talking.
We’re listening.

When PET radiotracers are introduced into the body, cancer absorbs them and acts as a biological beacon, which our machine can use to track and treat cancer in real time.

Targeting Cancer

Good news for organs. Bad news for tumors.

Our technology aims to deliver high doses of radiation to tumors, even while in motion, for greater impact to the tumor with less dose to the surrounding tissue.

Metastatic Disease

A world where stage is just a number.

Most patients with stage four cancer are not considered candidates for definitive radiotherapy due to the challenge of treating multiple tumors. Our breakthrough technology is challenging that and aims to treat multiple tumors, in parallel, during a single session. 

Discover the Potential

Combination Treatment

Come at cancer from every angle.

Treatment isn’t a one-size-fits-all situation. For many patients, the best treatment plan is a combination of multiple therapies. RefleXion will work together with chemotherapy, immunotherapy and targeted drugs for potentially better outcomes.

Understanding Radiotherapy Part 2: How Much Radiation is the Right Amount?

This week’s post will build upon what we learned in our last entry, which reviewed the basics of radiotherapy. I highly recommend reading that post if you have not already, but a very quick summary is that radiotherapy can be thought of as shooting billions of tiny bullets at cancer cells, causing those cancer cells […]
