Radiation oncologists use precisely directed beams of radiation to kill cancer cells or keep them from growing and dividing. Radiation therapy is a treatment option for many cancers.
External beam radiation techniques use a device called a linear accelerator to deliver high-dose X-rays to cancerous tissue. More and more, sophisticated image-guided systems allow radiation oncologists to "shape" the radiation dose exactly to outer limits of the tumor, delivering a higher dose of radiation with more precision and avoiding health tissues.
Stereotactic Body Radiation Therapy
Froedtert & the Medical College of Wisconsin have offered Stereotactic Body Radiation Therapy (SBRT) since 2006. SBRT is a treatment technique that uses special equipment to position a patient and precisely deliver external radiation therapy to tumors in the body (except the brain).
TomoTherapy, a type of SBRT, is an advanced radiation therapy system that combines a unique spiral dose pattern with a built-in imaging unit. The spiral dose pattern enables the system to deliver radiation from hundreds of angles. The system's built-in CT scanner allows technicians to check the position of a tumor immediately before treatment, which gives physicians the flexibility to modify the treatment plan when tumors change in size or position. The Froedtert & the Medical College of Wisconsin Clinical Cancer Center was one of the first cancer programs in the nation with the TomoTherapy system.
Brain tumors and vascular disorders account for the majority of radiosurgical procedures performed today. Radiosurgical treatment provided by the Gamma Knife is effective at controlling tumor growth, and hemorrhaging from vascular malformations. This treatment procedure targets lesions in the brain so exactly that the risk of harming healthy tissue is minimized. In certain cases, Gamma Knife treatment may serve as an adjunct to standard neurosurgical therapy or as the preferred course of treatment when further traditional therapy is not recommended.
Radioembolization delivers a high dose of radiation directly to a liver tumor using a product called TheraSphere®. The procedure targets the cancer site with minimal effect on surrounding healthy tissues. Froedtert & the Medical College were the first in Wisconsin to offer this treatment.
Second Opinion Provides Options and Hope
Matt Saunders found out he had colorectal cancer and needed surgery right away. His sister urged him to get a second opinion. That appointment changed everything. "For the first time, I think my wife and I felt a sense of calm. We are going to beat this."
Runner With Cancer Experiences Best in Medicine and Compassion
Faced with a breast cancer diagnosis at age 34, Adrienne Ridgeway says she felt confident being in the hands of a team working every day to make her better. She says it was even better to know that she “was in the hands of caring people.”
