Ryght AI announced a board of experienced medical leaders to guide the next phase of its clinical trial AI work, as described in its October 7, 2025 press release.
Clinical trials are how new cancer treatments become standard care, yet many eligible patients never learn a trial exists. Tools that help match patients to studies can make research easier to reach outside large academic centers.
XRO physicians have long taken part in research and tumor boards across San Diego. Following developments in trial technology helps our team keep patients informed about options that may fit their diagnosis.

Sharp Health News reported on a new study that offers hope for people diagnosed with brain tumors.
Brain tumors can be among the hardest diagnoses to hear. Research that improves how these tumors are treated, or how long patients live well afterward, gives families real reasons for hope.
Radiation therapy is a core part of treatment for many brain tumors. XRO physicians use precise techniques such as stereotactic radiosurgery and image-guided radiation to target tumors while protecting healthy brain tissue, and they work alongside neurosurgeons and medical oncologists to bring new evidence into everyday care.

When former President Joe Biden's prostate cancer diagnosis made headlines, many men started asking questions about their own risk. Sharp Health News used the moment to share practical lessons.
Prostate cancer is one of the most common cancers in men. Talking with your doctor about screening, knowing your family history and acting on symptoms can all lead to earlier diagnosis, when more treatment options are available.
Radiation therapy is a proven treatment for prostate cancer at many stages. XRO offers advanced options, including image-guided radiation and SpaceOAR hydrogel, a spacer that helps reduce radiation to the rectum during treatment.

In this Sharp Health News feature, XRO radiation oncologist Dr. Croix Fossum shares what drives his work and how radiation treatment has changed.
Many people picture radiation as harsh or imprecise. Modern machines shape and aim each treatment to the tumor, often allowing shorter courses and fewer side effects. Just as important is a care team that explains each step and supports patients throughout.
Dr. Fossum's perspective reflects how our physicians approach every patient: careful planning with advanced technology, combined with time to listen and answer questions. The article is a helpful introduction for anyone about to begin treatment with XRO.

For decades, there were two primary treatments to cure prostate cancer: surgery or radiation. Modern technology has allowed both to leap forward, improving results for patients.
Men diagnosed today have more options than ever, and the right choice depends on the cancer's stage, overall health and personal priorities. Understanding how treatments have changed makes it easier to have an informed conversation with your care team.
XRO treats prostate cancer with precise, image-guided radiation, including shorter treatment courses for suitable patients and SpaceOAR hydrogel to help protect the rectum. Our physicians work with urologists to help each patient compare options.

We often hear that cancer is more common in older adults. Testicular cancer is different: it is frequently diagnosed in young men ages 15 to 45, and roughly half of cases are found in men ages 20 to 34.
Young men may not think of cancer as a risk, so awareness is key. Knowing what is normal for your body and seeing a doctor about any lump, swelling or change can lead to early diagnosis. Testicular cancer is highly treatable, especially when found early.
Radiation therapy is one treatment option for certain types and stages of testicular cancer. XRO physicians work with urologists and medical oncologists to choose the approach that best balances cure with long-term health.
