Radiotherapy After Breast Conserving Surgery
You usually have radiotherapy to the whole breast after having breast conserving surgery . You generally start it about 4 to 6 weeks after surgery.
If you need to have chemotherapy you have this before your radiotherapy.
People with a very low risk of the cancer coming back may only have part of the breast treated with radiotherapy. Or they may not have radiotherapy at all.
Are Some Therapies More Effective Based On Stage
The type of radiation treatment you get depends on the stage of breast cancer. People with early to stage 3 breast cancer will benefit most from radiation treatment. Radiation can also help ease side effects in people with advanced breast cancer.
External whole breast radiation works best:
- for early stage to stage 3 breast cancer
- for tumors that are an inch or smaller
- if the cancer is in one spot
- if you had breast-saving surgery or a mastectomy
External beam radiation can also help treat side effects of advanced breast cancer.
Internal radiation works best:
- for early stage breast cancer
- if the cancer is in one spot
- if you had breast-saving surgery or a mastectomy
Sometimes, a person with advanced breast cancer will have internal radiation.
Intraoperative radiation works best:
- during early stage breast cancer
- when the tumor is too close to healthy tissue for external radiation to be possible
Not everyone can have intraoperative radiation or internal beam radiation. Whether you can have these procedures depends on:
- size and location of the tumor
- size of your breast
Types Of Radiation Therapy
- External beam radiation is most commonly used to treat breast cancer. A machine outside your body aims a beam of radiation on the area affected by the disease.
- Brachytherapy delivers radiation to the cancer through something implanted in your body.
- Proton therapy sends highly targeted radiation just to your breast tissue and not into your heart or lungs.

ON THIS PAGE: You will learn about the different types of treatments doctors use for people with breast cancer. Use the menu to see other pages.
This section explains the types of treatments that are the standard of care for early-stage and locally advanced breast cancer. Standard of care means the best treatments known. When making treatment plan decisions, you are strongly encouraged to consider clinical trials as an option. A clinical trial is a research study that tests a new approach to treatment. Doctors want to learn whether the new treatment is safe, effective, and possibly better than the standard treatment. Clinical trials can test a new drug and how often it should be given, a new combination of standard treatments, or new doses of standard drugs or other treatments. Some clinical trials also test giving less treatment than what is usually done as the standard of care. Clinical trials are an option to consider for treatment and care for all stages of cancer. Your doctor can help you consider all your treatment options. Learn more about clinical trials in the About Clinical Trials and Latest Research sections of this guide.

Radiation For Metastatic Breast Cancer
Sometimes breast cancer spreads to other parts of the body. When this happens, the breast cancer is called metastatic or stage IV.
If youve been diagnosed with metastatic breast cancer and are having symptoms, your doctor may recommend radiation therapy to:
- ease pain
- lower the risk of a cancer-weakened bone breaking
- open a blocked airway to improve breathing
- reduce pressure on a pinched spinal cord or nerve that might be causing pain, numbness, or weakness
- treat cancer that has spread to the brain
The radiation dose and schedule to treat metastatic breast cancer depends on a number of factors, including:
- the level of pain or amount of function lost
- the size of the cancer
- the location of the cancer
- the amount of previous radiation youve had
- the schedule for any other treatments
When Does Someone With Breast Cancer Get Radiation Therapy
The timing for radiation therapy depends on several factors. The treatment may take place:
- After a lumpectomy: A lumpectomy removes the cancerous tumor, leaving most of the breast. Radiation therapy lowers your risk of cancer coming back in the remaining breast tissue or nearby lymph nodes as well as reduces your chance of passing away of breast cancer.
- After a mastectomy: Most people dont get radiation therapy after a mastectomy . Your provider may recommend radiation if the tumor was larger than 5 cm if theres cancer in surrounding lymph nodes, skin tissue or muscle or if all the cancer can’t be removed .
- Before surgery: Rarely, healthcare providers use radiation to shrink a tumor before surgery.
- Instead of surgery: Sometimes, providers use radiation therapy to shrink a tumor that they cant surgically remove . A tumor may be unresectable due to its size or location. Or you may not be a candidate for surgery because of concerns about your health.
- To treat cancer spread: Stage 4 breast cancer is cancer that spreads to other parts of the body. Your provider may use radiation therapy to treat cancer that spreads to other parts of the body.
If you had surgery, radiation therapy typically starts about one month after the incision heals if chemotherapy is not received. Some individuals receive chemotherapy after surgery, followed by radiation therapy. You may get the two treatments at the same time.

Survival Happens Every Day
These rough estimates for how long breast cancer takes to treat can be helpful to plan your life around treatment. More importantly, they provide a light at the end of the tunnel for you to focus on. However, for your daily sanity, it may be better to break down your treatment into smaller parts. Take it from one day to the next. Remember, every day you make it, youre already winning. These factors all affect how long breast cancer takes to treat.

What Happens Before During And After Treatment
Once the diagnosis has been made, you will probably talk with your primary care physician along with several cancer specialists, such as a surgeon, a medical oncologist and a radiation oncologist, to discuss your treatment choices. These specialists will work together to help recommend the best treatment for you. In some cases, your cancer will need to be treated by using more than one type of treatment. For example, if you have breast cancer, you might have surgery to remove the tumor , then have radiation therapy to destroy any remaining cancer cells in or near your breast . You also might receive chemotherapy to destroy cancer cells that have traveled to other parts of the body.
Radiation Therapy Timing And Breast Reconstruction
The timing of radiation treatment in your overall breast cancer treatment plan depends on your individual situation and the characteristics of the breast cancer.
In many cases, radiation therapy is given after surgery. If chemotherapy is planned after surgery, radiation usually follows chemotherapy.
If youre having mastectomy and have decided to have breast reconstruction, its important to know that radiation can cause a reconstructed breast to lose volume and change color, texture, and appearance.
In particular, radiation therapy is known to cause complications with implant reconstruction. Research also suggests that a reconstructed breast may interfere with radiation therapy reaching the area affected by cancer, though this can vary on a case-by-case basis.
For these reasons, some surgeons advise waiting until after radiation and other treatments, such as chemotherapy, are completed before breast reconstruction surgery is done.
Other surgeons may recommend a more staged approach, which places a tissue expander after mastectomy to preserve the shape of the breast during radiation treatments. Once radiation is completed and the tissues have recovered, the expander that was used to maintain the shape of the breast is removed and replaced with tissue from another part of the body or a breast implant.

What Are Clinical Trials
Cancer specialists regularly conduct studies to test new treatments. These studies are called clinical trials. Clinical trials are available through cancer doctors everywhere- not just in major cities or in large hospitals.
Some clinical studies try to determine if a therapeutic approach is safe and potentially effective. Many large clinical trials compare the more commonly used treatment with a treatment that cancer experts think might be better. Patients who participate in clinical trials help doctors and future cancer patients find out whether a promising treatment is safe and effective. All patients who participate in clinical trials are carefully monitored to make sure they are getting quality care. It is important to remember that clinical trials are completely voluntary. Patients can leave a trial at any time. Clinical trials testing new treatments are carried out in phases:
Only you can make the decision about whether or not to participate in a clinical trial. Before making your decision, it is important to learn as much as possible about your cancer and the clinical trials that may be available to you. Your radiation oncologist can answer many of your questions if you are considering taking part in a trial or contact the National Cancer Institute at 1-800-4-CANCER or www.cancer.gov.
During Your Radiation Treatments
Your radiation therapists will bring you to the treatment room and help you lie on the treatment table . Youll be positioned exactly how you were during your simulation and set-up procedure. Your radiation therapists will do everything they can to make sure youre comfortable. Then, theyll leave the room, close the door, and start your treatment.
Figure 2. An example of a radiation treatment machine
Breathe normally during your treatment, but dont move. You wont see or feel the radiation, but you may hear the machine as it moves around you and is turned on and off. Your radiation therapists will be able to see you on a monitor and talk with you through an intercom during your whole treatment. Tell them if youre uncomfortable or need help.
Youll be in the treatment room for 10 to 20 minutes, depending on your treatment plan. Most of this time will be spent putting you in the correct position. The actual treatment only takes a few minutes.
Your radiation treatment wont make you or your clothes radioactive. Its safe for you to be around other people.

Intensity Modulated Radiation Therapy
Intensity modulated radiation therapy, or IMRT, is a specialized form of 3D-CRT that allows radiation to be more exactly shaped to fit the tumor. With IMRT, the radiation beam can be broken up into many “beamlets,” and the intensity of each beamlet can be adjusted individually. Using IMRT, it may be possible to further limit the amount of radiation that is received by healthy tissue near the tumor. In some situations, this may also allow a higher dose of radiation to be delivered to the tumor, potentially increasing the chance of a cure.
How Much Radiation Therapy Costs
Radiation therapy can be expensive. It uses complex machines and involves the services of many health care providers. The exact cost of your radiation therapy depends on the cost of health care where you live, what type of radiation therapy you get, and how many treatments you need.
Talk with your health insurance company about what services it will pay for. Most insurance plans pay for radiation therapy. To learn more, talk with the business office at the clinic or hospital where you go for treatment. If you need financial assistance, there are organizations that may be able to help. To find such organizations, go to the National Cancer Institute database, Organizations that Offer Support Services and search for “financial assistance.” Or call toll-free 1-800-4-CANCER to ask for information on organizations that may help.

Radiation For Breast Cancer
Radiation therapy is treatment with high-energy rays that destroy cancer cells. Some women with breast cancer will need radiation, in addition to other treatments. Radiation therapy is used in several situations:
- After breast-conserving surgery , to help lower the chance that the cancer will come back in the same breast or nearby lymph nodes.
- After a mastectomy, especially if the cancer was larger than 5 cm , if cancer is found in many lymph nodes, or if certain surgical margins have cancer such as the skin or muscle.
- If cancer has spread to other parts of the body, such as the bones or brain.
The main types of radiation therapy that can be used to treat breast cancer are external beam radiation therapy and brachytherapy.
Neoadjuvant And Adjuvant Systemic Therapy
For women who have a hormone receptor-positive breast cancer, most doctors will recommend hormone therapy as an adjuvant treatment, no matter how small the tumor is. Women with tumors larger than 0.5 cm across may be more likely to benefit from it. Hormone therapy is typically given for at least 5 years.
If the tumor is larger than 1 cm across, chemo after surgery is sometimes recommended. A woman’s age when she is diagnosed may help in deciding if chemo should be offered or not. Some doctors may suggest chemo for smaller tumors as well, especially if they have any unfavorable features .
After surgery, some women with HER2-positive cancers will be treated with trastuzumab for up to 1 year.
Many women with HER2-positive cancers will be treated with trastuzumab followed by surgery and more trastuzumab for up to 1 year. If after neoadjuvant therapy, residual cancer is found during surgery, trastuzumab may be changed to a different drug, called ado-trastuzumab emtansine, which is given every 3 weeks for 14 doses. If hormone receptor-positive cancer is found in the lymph nodes, your doctor might recommend one year of trastuzumab followed by additional treatment with an oral drug called neratinib for 1 year.

What Is Radiation Therapy
According to the National Cancer Institute, radiation therapy uses high energy rays or particles to kill cancer cells.
Radiation kills or slows the growth of cancer cells. While it also affects nearby healthy cells, the healthy cells typically recover after the course of radiation treatment has ended. Doctors try to protect healthy cells by:
- using as low a dose of radiation as possible
- spreading out treatment over time
- aiming the radiation at a very specific part of your body
The most common type of radiation therapy is external beam radiation, according to the American Cancer Society.
With external beam radiation, a machine directs high energy beams of radiation at the area where the cancer cells have been found.
Radiation therapy can be used in a variety of instances for breast cancer treatment. It can be used:
- after breast-conserving surgery, to reduce the risk of recurrence in your breast
- after a mastectomy, particularly if:
- the tumor was larger than 5 centimeters
- there was cancer in your lymph nodes
- the margins were positive
Depending on the type of breast cancer and the cancer stage, it can be used with other cancer treatments like surgery and chemotherapy,
There are two main types of radiation therapy: external beam radiation and internal radiation. Some people have both types of treatment.
Keeping Health Insurance And Copies Of Your Medical Records
Even after treatment, its very important to keep health insurance. Tests and doctor visits cost a lot, and even though no one wants to think of their cancer coming back, this could happen.
At some point after your treatment, you might find yourself seeing a new doctor who doesnt know about your medical history. Its important to keep copies of your medical records to give your new doctor the details of your diagnosis and treatment. Learn more in Keeping Copies of Important Medical Records.
