What Is Radiation Like for Breast Cancer?
Radiation therapy for breast cancer is a powerful tool used to destroy remaining cancer cells after surgery and/or chemotherapy, aiming to prevent recurrence. While incredibly effective, experiencing radiation therapy can vary significantly from person to person, involving a range of potential side effects and requiring diligent self-care to manage.
Understanding Radiation Therapy for Breast Cancer
Radiation therapy uses high-energy rays or particles to damage the DNA of cancer cells, preventing them from growing and dividing. It’s a common component of breast cancer treatment plans, often used after lumpectomy (breast-conserving surgery) or mastectomy to eliminate any microscopic cancer cells that may have been left behind. The goal is to reduce the risk of the cancer returning, either locally (in the breast or chest wall) or regionally (in the lymph nodes).
Radiation therapy is typically delivered in one of two main ways:
- External Beam Radiation Therapy (EBRT): This is the most common type. A machine outside the body directs radiation beams at the breast, chest wall, and/or lymph nodes.
- Internal Radiation Therapy (Brachytherapy): Also known as accelerated partial breast irradiation (APBI), this involves placing radioactive seeds or catheters directly into the breast tissue, delivering radiation from the inside. This method is usually reserved for early-stage breast cancer.
The experience of undergoing radiation therapy varies from person to person, and depends on several factors, including the type of radiation used, the dose of radiation, the area being treated, and the individual’s overall health. It’s important to openly discuss any concerns or questions with your radiation oncologist.
What to Expect During Radiation Treatment
During radiation therapy, patients typically receive treatment five days a week for several weeks (usually three to six weeks for EBRT and one week for brachytherapy). Each session usually lasts between 15 and 30 minutes, but the actual radiation exposure is only a few minutes long.
Before starting treatment, a simulation is performed. This involves taking detailed measurements and images to precisely map out the treatment area and ensure the radiation is delivered accurately. During the simulation, small ink marks or tattoos may be placed on the skin to serve as reference points for each treatment session.
During the actual treatment, the patient lies on a table while the radiation therapist positions the machine and monitors the process from a nearby room. Patients typically don’t feel anything during the radiation treatment itself, similar to getting an X-ray.
Common Side Effects of Radiation Therapy
Radiation therapy can cause a range of side effects, which can vary in severity and duration. It’s important to remember that not everyone experiences the same side effects, and many can be managed effectively.
Skin Changes
One of the most common side effects is skin irritation in the treated area. This can range from mild redness and dryness (similar to a sunburn) to more severe blistering and peeling. Using gentle skincare products, avoiding harsh soaps and lotions, and wearing loose-fitting clothing can help minimize skin irritation. Radiation oncologists often recommend specific creams and ointments to soothe and protect the skin.
Fatigue
Fatigue is another common side effect, and it can be significant. This is because the body is working hard to repair the damage caused by the radiation. Rest is essential, and pacing activities throughout the day can help manage fatigue.
Other Potential Side Effects
Other potential side effects include:
- Swelling in the breast or arm
- Pain or soreness in the treated area
- Changes in breast size or shape
- Lymphedema (swelling in the arm or hand on the side of the body where the cancer was treated)
- Pneumonitis (inflammation of the lungs, which can cause shortness of breath and cough) – this is less common but more serious.
- Heart problems (very rare and typically occur many years after treatment)
Frequently Asked Questions (FAQs)
FAQ 1: Will I lose my hair from radiation therapy for breast cancer?
Hair loss is unlikely with radiation therapy targeted at the breast. However, if the treatment area includes the underarm lymph nodes, some hair loss may occur in that area. Unlike chemotherapy, radiation therapy only affects the hair follicles in the direct path of the radiation beam.
FAQ 2: Can I get radiation burns from breast cancer treatment?
While the term “burn” is often used, it’s more accurately described as skin irritation or inflammation. The skin in the treated area may become red, dry, itchy, or sensitive. Following your radiation oncologist’s skincare recommendations is crucial to minimize these effects. Severe blistering is less common with modern radiation techniques.
FAQ 3: What can I do to manage the fatigue caused by radiation therapy?
Managing fatigue is essential. Prioritize rest, maintain a healthy diet, and engage in light exercise as tolerated. Avoid strenuous activities and listen to your body. Many patients find that naps and short breaks throughout the day are helpful.
FAQ 4: Is radiation therapy painful?
The radiation treatment itself is painless. However, the side effects, such as skin irritation or soreness, can cause discomfort. Your radiation oncology team can provide pain relief options, if needed.
FAQ 5: Will radiation therapy affect my fertility?
Radiation therapy to the breast usually does not directly affect fertility. However, if chemotherapy is also part of your treatment plan, it can impact fertility. It’s important to discuss your fertility concerns with your oncologist before starting treatment.
FAQ 6: Can I wear a bra during radiation therapy?
It’s generally recommended to avoid wearing a bra or wear a soft, non-wired bra during and after radiation treatment. This helps to minimize friction and irritation on the treated skin. Your radiation oncologist can provide specific recommendations based on your individual situation.
FAQ 7: How long does it take for the skin to heal after radiation therapy?
The skin typically begins to heal within a few weeks after completing radiation therapy. However, it can take several months for the skin to fully recover. Consistent skincare, as recommended by your radiation oncologist, is essential during this period.
FAQ 8: Can I swim during radiation therapy?
It is generally advised to avoid swimming pools, hot tubs, and saunas during radiation therapy due to the potential for skin irritation and infection. Discuss this with your radiation oncologist, as they can provide personalized recommendations.
FAQ 9: What is the long-term outlook after radiation therapy for breast cancer?
The long-term outlook after radiation therapy for breast cancer is generally very good, with many women experiencing long-term remission. Regular follow-up appointments with your oncologist are essential to monitor for any potential side effects or recurrence.
FAQ 10: Can I have reconstruction surgery after radiation therapy?
Yes, breast reconstruction is possible after radiation therapy. However, radiation can affect the tissues and may complicate the reconstruction process. It’s important to discuss the timing and type of reconstruction with your plastic surgeon and radiation oncologist.
FAQ 11: Is there anything I can do to prevent lymphedema after radiation therapy?
Early detection and management are key to preventing lymphedema. Avoid injury to the affected arm or hand, protect your skin from cuts and burns, maintain a healthy weight, and engage in gentle exercises. If you notice any swelling, contact your doctor immediately.
FAQ 12: Are there alternative therapies I can use alongside radiation for breast cancer?
While some complementary therapies may help manage side effects, it’s crucial to discuss them with your oncologist before starting. Some therapies may interfere with radiation treatment or have other adverse effects. Open communication with your medical team is essential to ensure safe and effective care.
Moving Forward After Radiation
Radiation therapy is a significant part of many breast cancer treatment plans, and understanding what to expect can help you feel more prepared and empowered. Open communication with your radiation oncology team is essential throughout the entire process. By working together, you can manage side effects, optimize your treatment, and achieve the best possible outcome. Remember that you are not alone in this journey, and support is available from your medical team, family, friends, and support groups.
