Going Through Radiation Therapy
Radiation therapy can harm normal tissue, so it’s carefully planned and precisely delivered. This helps ensure the radiation kills as many cancer cells as possible while doing as little injury as possible to other parts of your body.
Radiation therapy is planned specifically for your breast cancer and the shape of your body. This is why sessions can’t be split between different treatment centers.
Your treatment plan is based on:
- Tumor size, type and location
- The number of lymph nodes with cancer
- The type of breast surgery (and lymph node surgery) you had
- The shape of your breast, and the shape and location of nearby organs (such as your heart and lungs)
Planning session
Your radiation oncologist oversees the radiation planning session.
You will lie on a special table while your radiation oncologist decides the proper dose of radiation and where to give the radiation. He or she will use a CT scan to guide the radiation planning.
During the planning session, your radiation oncologist will put small marks (about the size of a pinhead) on your skin.
These marks ensure you are correctly positioned for each treatment. They may be ink spots, or they may be permanent tattoos. If they are ink spots, don’t wash them off until you finish all of your radiation therapy.
You may be asked to hold your breath during the planning session. This is one way to minimize radiation exposure to the heart.
Radiation therapy sessions
Your radiation oncologist leads a team of technicians and nurses. The team will work with you at each radiation therapy session.
What should I expect?
During each session, you will lie on a special table.
You may be asked to hold your breath while the radiation is given. This is one way to minimize radiation exposure to the heart.
If lymph nodes were removed during surgery and contained cancer, often the area around the lymph nodes is also treated with radiation.
Each session lasts about 10-20 minutes. Most of this time is spent positioning your body to ensure the treatment is given exactly as planned.
With any standard radiation therapy (whole-breast radiation therapy, accelerated, hypofractionated whole-breast irradiation, partial breast irradiation or a boost) you will not be radioactive when you leave the radiation treatment center. You will not pose any radiation risk to your family, including your pets.
How often will I go for treatment?
Treatment is usually given once a day, 5 days a week, for 3-6 weeks.
The schedule of radiation sessions is designed to treat your breast cancer and varies from person to person.

Transportation, lodging, child care and elder care assistance
If you don’t live near the radiation treatment center, it can be hard to get to and from therapy sessions.
Sometimes, there are programs that help with local or long-distance transportation and lodging.
There are also programs to help you with child care and elder care costs.
