Radiation Oncology

Radiation therapy destroys cancer cells by directing a high-energy beam to the cancer site with minimal harm to healthy cells. One of the most common treatments for cancer, radiation therapy is targeted and minimally invasive compared to surgery or chemotherapy. Often, radiation treatment is given concurrently or in combination with other forms of cancer treatment to maximize positive results.

Radiation does not affect cancer cells right away—it takes days or weeks of treatment before cancer cells deteriorate. Radiation continues to affect cancer cells after treatments are complete, and are given daily Monday-Friday for a period of time prescribed by your radiation oncologist.

Coming Soon: New Linear Accelerator (Linac)
Cooley Dickinson is currently installing a new, advanced linear accelerator unit (linac) which will more precisely target radiation treatments and dramatically shorten their duration. For patients who require external beam radiation therapy for cancer treatment, the Vitkauskas Crowe Radiation Oncology Suite, part of the Mass General Cancer Center at Cooley Dickinson Hospital, will offer treatment using equipment that more precisely targets tumors while minimizing side effects. The new linac’s precision and power will allow us to provide radiation treatment to patients in 8-12 minutes that now requires roughly half an hour.

New Techniques

Tumors are painstakingly targeted during radiation therapy to make sure that as much healthy tissue as possible remains unaffected, but these precise calculations can be skewed to some degree by movement due to normal breathing during treatment. The Mass General Cancer Center at Cooley Dickinson Hospital now employs a promising new technique known as Deep Inspiration Breath Hold (DIBH), which allows radiation beam emitters to be adjusted to compensate for patient motion during treatment sessions. The practice, which can be used in treatment of lung, liver and other thoracic cancers, has received very positive clinical reviews and is recommended by The American Society for Radiation Oncology (ASTRO). The technique has been noted as especially effective in sparing healthy tissues in the heart during treatment of cancers of the left breast.

Wonderful People Doing Wonderful Work

In Feb. 2014, I was diagnosed with throat cancer. With that scary conclusion, the most important relationships of my life were formed and my connection with Cooley Dickinson began. The words “thank you” just don’t seem enough to express the gratitude I feel for everyone that helped me, and my wife, through my cancer diagnosis, treatment and recovery. These people are truly my angels. I want to let everyone know how precious these people are to me, my wife, and this community!”
