We’re here to help

If you or someone you care about has just been diagnosed with cancer, or told they need radiation therapy, it’s likely that everything is new.

We believe that every patient should have access to safe, comfortable and accurate treatment provided by a skilled and caring team. Our mission is to provide you important information about radiation therapy so that you can be prepared for shared decision-making conversations with your doctor, find a treatment center that’s right for you, and access a community that is here to support you.

Radiation Therapy Side Effects

High doses of radiation are used to target and destroy cancer cells. To help ensure that all the cancer is destroyed, doctors deliver radiation with a margin (an area of healthy cells), surrounding the cancer area. This is to ensure that no abnormal cells are missed. During and after treatment, the radiation damages both cancerous and healthy cells. The cancerous cells are not able to repair themselves and heal, while the healthy cells can typically heal. This is the reason for treating in several fractions (small doses over several days), which gives healthy cells a chance to recover. The cells recovering is what often causes fatigue — the most common side effect of radiation therapy. Each organ in the body or type of tissue can withstand certain amounts of doses of radiation. When radiation is delivered to different areas of the body, different side effects will occur. Some side effects are short-term, while others are longer-term. Some side effects are enhanced or made worse by concurrent chemotherapy treatments. Side effects are most common within, or due to changes within, the treatment area (including the margin) that received radiation.

A New Standard in Radiation Therapy

If you need radiation therapy, it’s important to ensure the radiation reaches the right place, while avoiding vital organs such as the heart. To do this, a variety of methods are used to ensure you are in the right place before and during treatment. These methods range from tattooing your body and taking additional X-Rays to using devices that limit movement of certain areas of the body.

AlignRT® is a new technology which ensures that you are positioned correctly before and during treatment. By tracking your skin surface in real time using 3D camera technology, AlignRT® helps make sure that you are in the intended position, with high accuracy, and often with fewer bothersome devices, providing both comfort and safety. If you move even a millimeter, radiation can be automatically shut off until you are back in the correct position. AlignRT® can be used across all cancer sites and can eliminate the need for tattoos or skin marks for certain patients.

AlignRT® is available in 70% of the US News & World Report “Best 50 Hospitals for Cancer”.
