Radiation therapy services

​​​​​​​​Radiation therapy uses high-energy X-rays to kill cancer cells.

It may be used in several ways:

  • To cure or shrink cancer before surgery or after surgery to prevent cancer returning. Radiation therapy may also be given with chemotherapy. 
  • To stop the cancer from recurring in another area. 
  • To treat symptoms related to cancer. Radiation therapy may help relieve symptoms such as pain, trouble breathing or swallowing, or bowel problems caused by cancer that has spread or grown too far to be considered curable.

Radiation therapy services at Marshfield Clinic include:

  • Intensity Modulated Radiation Therapy (IMRT): IMRT allows the strength of the radiation beams to be adjusted. In effect, it decreases the radiation reaching normal tissue while delivering a higher dose to the cancerous tissue. 
  • Brachytherapy 
  • Eye Plaque 
  • Gamma Knife 
  • Intraoperative Radiation 
  • High Dose Radiation 
  • Telemedicine 
  • Stereotactic Body Radiation Therapy (SBRT) is a cancer therapy that shrinks the number of treatment sessions needed to reduce or eliminate the cancer.
  • Stereotactic Radiosurgery: This therapy delivers a large, precise dose of radiation to a small tumor area. This is commonly used to treat brain and spinal cord tumors. 
  • Intraoperative Radiation Therapy: Delivers radiation to the cancer during surgery. 
  • Sophisticated Treatment Planning with CT Guided 3-D Simulation: This uses CT images and computers to map the location of a cancer in three dimensions. The radiation beams are matched to the shape of the tumor and delivered to the tumor from several directions. This decreases the amount of radiation that goes through any one area of normal tissue and improves effectiveness by increasing the radiation dose directed at the cancer.
  • Tomotherapy
  • ​Image Guided Radiation Therapy (IGRT)​​

Test Your Knowledge of Cancer's Warning Signs

Early detection of cancer is important because it is usually easier to treat—and possibly cure—when caught early. Do you know what signs to look for? Take this quiz to find out more.

1. Any sudden or progressive change in a mole's appearance could be a sign of skin cancer.
2. A new mole or a change in an existing mole may be a sign of skin cancer.
3. One sign of malignant melanoma is a mole with shades of tan, brown, black, or blue.
4. Changes, lumps, or hard masses in the testicles are signs of testicular cancer.
5. A change in bowel habits—blood in the stool or chronic constipation—is a common symptom of stomach cancer.
6. Lumps, hard knots, or a thickening in the breast could mean breast cancer.
7. A nagging cough or hoarseness could be signs of lung cancer.
8. Prostate cancer often has no symptoms in its early stages.
9. Symptoms of mouth or tongue cancer include a sore inside the mouth that doesn't heal and mouth pain that doesn't get better or go away.
10. Bladder cancer has no symptoms.
