What to Expect During Breast Cancer Radiation Treatments

Introduction

Breast cancer remains one of the most prevalent cancers worldwide, affecting millions of women each year. Fortunately, advancements in medical science have provided various treatment options, one of the most effective being breast cancer radiation therapy. This treatment plays a crucial role in eliminating cancer cells, reducing recurrence risks, and improving survival rates.

If you or a loved one has been diagnosed with breast cancer and your healthcare provider has recommended radiation therapy, understanding the process, benefits, and side effects is essential. This guide, brought to you by Breast Cancer Texas, will delve into everything you need to know about breast radiation treatment, ensuring you make informed decisions on your journey to recovery.

What is Breast Cancer Radiation Therapy?

Radiation therapy is a highly targeted treatment that uses high-energy X-rays or protons to destroy cancerous cells in the breast. It is often recommended after surgery to eliminate any remaining cancer cells and lower the chance of recurrence.

There are two primary types of breast radiotherapy:

  • External Beam Radiation Therapy (EBRT): The most common type of breast cancer radiation therapy is external beam radiation, where a large machine outside the body delivers high-energy radiation beams directly to the affected breast area, targeting any remaining cancer cells after surgery or other treatments. This is typically given daily for several weeks.
  • Internal Radiation (Brachytherapy): Brachytherapy, also known as internal radiation therapy, involves placing a radioactive source, such as seeds, ribbons, or a catheter, directly inside the breast tissue near the tumor bed. This technique is often used for patients undergoing partial breast radiation after a lumpectomy, delivering a highly targeted dose of radiation to the specific area while minimizing exposure to surrounding healthy tissues.

Who Needs Breast Radiation Treatment

Your oncologist may recommend radiation therapy ion

  • You have undergone a lumpectomy (breast-conserving surgery), as radiation helps prevent recurrence.
  • You had a mastectomy but had cancer in multiple lymph nodes.
  • Your tumor is large or aggressive, increasing the likelihood of cancer cells remaining post-surgery.
  • Your cancer has spread to the lymph nodes.

How is Breast Cancer Radiation Therapy Administered?

Step 1: Consultation & Planning

Before starting radiation, your healthcare team will conduct a CT scan to map the treatment area precisely. A radiation oncologist will then design a customized treatment plan to ensure the surrounding healthy tissues remain unharmed.

Step 2: Radiation Treatment Sessions

  • Typically, radiation therapy lasts three to six weeks, with sessions five days a week.
  • Each session takes about 15–30 minutes.
  • The patient lies on a table while the radiation machine targets the designated area.
  • The procedure is painless, much like getting an X-ray.

Step 3: Post-Treatment Care

After the full course of radiation therapy, patients may experience fatigue, skin irritation, or swelling. Your doctor will provide guidance on managing these side effects effectively.

Benefits of Breast Radiotherapy

  • Reduces Recurrence: Radiation therapy plays a crucial role in breast cancer treatment, significantly lowering the risk of local recurrence, meaning the cancer returning in the treated breast or nearby lymph nodes. It is often a key component of a comprehensive treatment plan, especially after surgery like a lumpectomy or mastectomy.
  • Non-Invasive & Painless: Unlike chemotherapy, which often involves intravenous infusions and can have systemic side effects, radiation therapy for breast cancer does not require IVs and the treatment itself is typically pain-free. Patients may experience some skin irritation or fatigue, but the radiation delivery process itself is not painful.
  • Improves Long-Term Survival Rates: Extensive studies and clinical trials have consistently demonstrated that patients who undergo breast cancer therapy that includes radiation treatment, when appropriate, generally experience significantly better long-term outcomes, including improved survival rates and a reduced risk of cancer recurrence compared to those who do not receive radiation. This is particularly true after lumpectomy and in certain cases after mastectomy.
  • Preserves Breast Tissue: For patients undergoing a lumpectomy, a breast-conserving surgery that removes only the tumor and a small margin of surrounding tissue, radiation therapy plays a vital role. It ensures that any remaining microscopic cancer cells are destroyed, maximizing the chances of eliminating the cancer while allowing patients to keep most of their natural breast tissue and achieve a better cosmetic outcome.

Side Effects & How to Manage Them

While radiation therapy is effective, it may lead to some side effects. Here’s what to expect and how to manage them:

Common Side Effects:

  • Skin Irritation & Redness: Similar to sunburn, the treated area may feel sensitive.
  • Fatigue: Many patients feel tired due to their body’s healing response.
  • Swelling & Tenderness: The breast may swell slightly, but this typically subsides.
  • Changes in Breast Texture: Some patients report firmness or shrinkage over time.

Tips for Managing Side Effects:

  • Apply moisturizers (approved by your doctor) to soothe skin.
  • Wear loose-fitting clothing to avoid irritation.
  • Maintain a healthy diet rich in vitamins and proteins to aid recovery.
  • Get plenty of rest and light exercise to boost energy levels.

Life After Breast Radiation Treatment

Many women resume normal activities soon after completing radiation therapy. However, follow-up care is essential to monitor recovery and detect any potential issues early.

Key Post-Treatment Recommendations:

  • Regular Checkups: Your oncologist will schedule follow-up visits every few months initially.
  • Mammograms: Annual screenings remain crucial to ensure no new growths.
  • Healthy Lifestyle: Eating nutritious foods, exercising, and avoiding smoking can enhance overall well-being.

Conclusion

Breast cancer radiation therapy is a vital component of treatment, offering hope and improved survival rates for many patients. While it comes with potential side effects, they can be managed with proper care and lifestyle adjustments.

4. Can I exercise during treatment?

Light exercises like walking and stretching are generally encouraged, but avoid high-impact activities that may irritate the treated area.

5. How soon can I have reconstructive surgery after breast cancer radiation therapy?

Doctors usually recommend waiting at least six months to a year after radiation to allow the breast tissue to heal fully.
