How Effective Is Radiation Therapy For Breast Cancer

Starting With Neoadjuvant Therapy

Radiation therapy effectiveness and options for breast cancer – Mayo Clinic

Most often, these cancers are treated with neoadjuvant chemotherapy . For HER2-positive tumors, the targeted drug trastuzumab is given as well, sometimes along with pertuzumab . This may shrink the tumor enough for a woman to have breast-conserving surgery . If the tumor doesnt shrink enough, a mastectomy is done. Nearby lymph nodes will also need to be checked. A sentinel lymph node biopsy is often not an option for stage III cancers, so an axillary lymph node dissection is usually done.

Often, radiation therapy is needed after surgery. If breast reconstruction is done, it is usually delayed until after radiation is complete. In some cases, additional chemo is given after surgery as well.

After surgery, some women with HER2-positive cancers will be treated with trastuzumab for up to a year. Many women with HER2-positive cancers will be treated first with trastuzumab followed by surgery and then more trastuzumab for up to a year. If after neoadjuvant therapy, any residual cancer is found at the time of surgery, trastuzumab may be changed to a different drug, called ado-trastuzumab emtansine, which is given every 3 weeks for 14 doses. For people with hormone receptor-positive cancer in the lymph nodes who have completed a year of trastuzumab, the doctor might also recommend additional treatment with an oral drug called neratinib for a year.

Types Of Cancer That Are Treated With Radiation Therapy

External beam radiation therapy is used to treat many types of cancer.

Brachytherapy is most often used to treat cancers of the head and neck, breast, cervix, prostate, and eye.

A systemic radiation therapy called radioactive iodine, or I-131, is most often used to treat certain types of thyroid cancer.

Another type of systemic radiation therapy, called targeted radionuclide therapy, is used to treat some patients who have advanced prostate cancer or gastroenteropancreatic neuroendocrine tumor . This type of treatment may also be referred to as molecular radiotherapy.

What Are The Side Effects Of Radiation

Radiation therapy can have side effects, and these vary from person to person.

The most common side-effects are:

  • Sunburn-type skin irritation of the targeted area
  • Red, dry, tender, or itchy skin
  • Breast heaviness
  • Discoloration, redness, or a bruised appearance
  • General fatigue

What should I do about side effects from breast cancer radiation?If you experience difficulty from side effects, you should discuss them with your doctor, who may be able to suggest ways you can treat side effects and help yourself feel more comfortable. These problems usually go away over a short period of time, but there may be a lasting change in the color of your skin.Here are some good general tips for dealing with the most common side effects of radiation:

It’s possible for your doctor to prescribe a medicine outside the uses it’s licensed for if they’re willing to take personal responsibility for this ‘off-licence’ use of treatment.

Your local clinical commissioning group may need to be involved, as it would have to decide whether to support your doctor’s decision and pay for the medicine from NHS budgets.

How Effective Is Radiation Therapy

Partial Breast Radiation as Effective as Entire Breast ...

If early-stage breast cancer hasnt spread, radiation therapy after a lumpectomy significantly reduces the risk of cancer coming back by approximately 50%. Studies show that a lumpectomy followed by radiation therapy is as effective as a mastectomy without radiation therapy.

People who undergo a lumpectomy have a 20% to 40% chance of the cancer coming back at 10 to 20 years. With the addition of postsurgical radiation therapy, that risk drops to 5% to 10%. However, there are some patients who derive less benefit from radiation including patients 65 years or older with small cancers.

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.

How Does Radiation Therapy Work

Radiation therapy uses special high-energy X-rays or particles to damage a cancer cells DNA. When a cancer cells DNA is damaged, it cant divide successfully and it dies.

Radiation therapy damages both healthy cells and cancer cells in the treatment area. Still, radiation affects cancer cells more than normal cells. Cancer cells grow and divide faster than healthy cells and also are less organized. Because of this, it’s harder for cancer cells to repair the damage done by radiation. So cancer cells are more easily destroyed by radiation, while healthy cells are better able to repair themselves and survive the treatment.

The treatment area may include the breast area, the lymph nodes, or another part of the body if the cancer has spread.

Radiation treatments are carefully planned to make sure you receive the greatest benefits and the fewest side effects possible.

Brachytherapy/Internal Radiation
Internal radiation, called brachytherapy by doctors, uses a radioactive substance sealed in seeds or tiny tubes that are placed inside your body directly into the cancer or the place where the cancer was. Read about brachytherapy.

Another type of radiation therapy, called intraoperative radiation therapy, is a type of partial-breast radiation. With intraoperative radiation therapy, the entire course of radiation is delivered at one time during breast cancer surgery. Read more about intraoperative radiation therapy.

Side Effects Of Radiotherapy

As well as killing cancer cells, radiotherapy can damage some healthy cells in the area being treated.

This can cause some side effects, such as:

  • sore, red skin
  • hair loss in the area being treated
  • feeling sick
  • a sore mouth
  • diarrhoea

Many of these side effects can be treated or prevented and most will pass after treatment stops.

External radiotherapy does not make you radioactive, as the radiation passes through your body.

The radiation from implants or injections can stay in your body for a few days, so you may need to stay in hospital and avoid close contact with other people for a few days as a precaution.

How Is Radiation Therapy For Breast Cancer Performed

Side Effects of Radiation Therapy for Breast Cancer?

Most people lie on their back during the treatment though some breast treatments are performed while lying on your stomach . You place your arm above your head .

During the treatment, your treatment team:

  • Positions and secures your body in the immobilization device. If you had a mastectomy, your provider might place a bolus on top of the treatment area to increase the radiation dose to the surface.
  • Lines up the machine with the first treatment field. To protect themselves from radiation exposure, providers leave the room. Your provider can still hear and see you.
  • Turns on the machine. You will hear a whirring noise, but you wont see the radiation beams. You must remain still. Depending on the radiation type and dose, treatment can take 30 seconds to several minutes.
  • Returns to the room to position the machine to treat a different treatment field. Most people get treatment on two to five fields each day.
  • Takes daily/weekly X-rays of the treatment field to make sure the radiation is hitting the correct area.

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.

What Should I Expect Before Radiation Therapy For Breast Cancer

Most people who have breast cancer treatment receive external beam radiation therapy. The goal is to destroy any remaining cancerous cells while protecting healthy tissue.

Before your first treatment, you will have a planning session . This simulation helps your provider map out the treatment area while sparing normal tissues . This session may take one hour or longer.

During the simulation, your provider:

  • Carefully positions your body in an immobilization device on the treatment table. This device helps you stay in the correct position for all treatments.
  • Uses techniques to reduce the dose to the heart and lungs
  • Uses a tattoo device to mark the corners of the treatment areas . The freckle-sized tattoos are permanent. These markings help your provider align the radiation treatment in the same manner each time.

    Breast Cancer: Radiation Therapy To The Left Breast And Double Risk Of Heart Disease

    Radiation therapy is an effective and widely used treatment for breast cancer. Almost half of women diagnosed with breast cancer undergo radiation therapy, which can expose the heart to accidental radiation. For those under 50 at the time of breast cancer diagnosis, the 10-year survival rate is over 90% for stage I disease and over 75% for stage II disease, explains lead author Dr Gordon Watt, Memorial Sloan Kettering Cancer Center researcher.

    Although the benefits of radiation therapy for breast cancer have been widely demonstrated, long-term complications can occur. Among these complications, the one revealed by this study carried out on young women with left breast cancer who had undergone radiotherapy: these patients have more than twice the risk of subsequent coronary heart disease compared to patients who have undergone the same treatment. , but for the right breast.

    Age Is A Major Factor In Determining What Type Of Radiation Therapy Women Should Receive

    Targeted Radiation Therapy Effective For Breast Cancer ...

    The good news is that both whole-breast and partial-breast radiation therapy after a lumpectomy are effective in preventing early-stage cancers from recurring, according to Dr. McCormick. But partial-breast radiation therapy may not be right for younger women who have not gone through menopause. Breast cancer in these women tends to be more aggressive and less likely to respond to treatments.

    Im very comfortable offering partial-breast irradiation to older women, Dr. McCormick says. Its a good choice for people who are interested in a short course of radiation and are not as worried about cosmetic issues.

    Even for older women, though, its important to look at all the individual factors, she explains. Women should talk to their doctor in order to make the best choice.

    Radiotherapy To The Lymph Nodes

    Radiotherapy can be given to the lymph nodes under the arm to destroy any cancer cells that may be present there.

    It may also be given to the lymph nodes in the lower part of the neck around the collarbone, or in the area near the breastbone .

    If radiotherapy to the lymph nodes is recommended, your specialist will explain why.

    When Radiotherapy Is Given

    Radiotherapy is given after surgery to reduce the risk of breast cancer coming back in the breast, chest area or lymph nodes.

    Your specialist or breast care nurse will tell you when you can expect to start radiotherapy.

    If youre having chemotherapy after surgery, radiotherapy is usually given after the chemotherapy.

    Radiotherapy may be delayed for a medical reason, for example if you need to wait for a wound to heal or if you develop a seroma .

    Radiotherapy may not be suitable if:

    • you have previously had radiotherapy to the same area
    • you have a medical condition that could make you particularly sensitive to its effects
    • youre pregnant

    Hypofractionated Vs Traditional Radiation Therapy

    In March 2018, the American Society for Radiation Oncology released updated guidelines on whole-breast radiation therapy saying that most people diagnosed with breast cancer should be treated with a hypofractionated radiation schedule.

    In many cases, people diagnosed with early-stage breast cancer have radiation therapy after surgery to remove the cancer. Radiation therapy lowers the risk of the cancer coming back .

    Whole-breast radiation therapy after breast cancer surgery is usually given as one treatment per day, 5 days a week, for 5 to 7 weeks. A Gray is the way radiation oncologists measure the dose of radiation therapy if youre on a 5-week treatment schedule, 50 Gy is the usual amount given during the 5 weeks . A supplemental boost dose may be included at the end of the regimen that targets the area where the cancer was.

    Radiation treatment schedules were developed based on research results. But a 5- to 7-week nearly daily commitment may be difficult for some people, especially if they live far away from a treatment center. So doctors developed and studied different radiation therapy schedules that involve fewer treatments with higher doses of radiation at each treatment, but about the same total radiation dose. These hypofractionated radiation schedules put the same radiation dose into a 3- to 5-week schedule, instead of a 5- to 7-week schedule.

    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

    These Steps Can Help:

    • Gently cleanse the treated area using lukewarm water and a mild soap. Donât rub your skin. Pat it dry with a soft towel, or use a hair dryer on a cool setting.
    • Donât scratch or rub the treated area. Use only an electric razor if you need to shave there. Donât put on medical tape or bandages.
    • Donât apply any ointment, cream, lotion, or powder to the treated area unless your doctor or nurse has prescribed it. This includes cosmetics, shaving lotions, perfumes, and deodorants.
    • Choose clothes made from natural fibers like cotton rather than tight-fitting clothing or harsh fabrics like wool or corduroy.
    • Avoid extreme heat or cold where you’ve had radiation — no electric heating pads, hot water bottles, or ice packs.
    • Also avoid hot tubs and tanning beds.
    • Stay out of direct sunlight, especially between the hours of 10 a.m. and 2 p.m., even after you’re done with treatment. The sun can intensify skin reactions and lead to severe sunburn. Choose a sunscreen of SPF 30 or higher. Wear protective clothing, such as a long-sleeved shirt, pants, and a wide-brimmed hat, too.

    What Are The Different Kinds Of Radiation Therapy

    Most radiation therapy is administered by a radiation oncologist at a radiation center and usually begins three to four weeks after surgery. The radiation is used to destroy undetectable cancer cells and reduce the risk of cancer recurring in the affected breast.

    There are two main kinds of radiation therapy that may be considered, and some people have both.

    • External Beam Breast Cancer Radiation
    • Internal Breast Cancer Radiation

    Keep in mind that the course of treatment you decide is something you should discuss with your radiation oncologist in order to ensure that it is as effective as possible.
