Radiation Therapy for Breast Cancer: A Patient's Guide
Wondering what radiation therapy for breast cancer entails? This article explains the different types of radiation, possible side effects, and what patients can expect during the treatment process.
Radiation therapy is one of the most common treatments for breast cancer, but it can be confusing to understand the details. This article will break down the different types of radiation therapy, the side effects you may experience, and what you should expect throughout the process.
What is Radiation Therapy for Breast Cancer?
Radiation therapy uses high-energy particles or waves, such as X-rays or protons, to target and destroy cancer cells. It is often used after surgery to kill any remaining cancer cells and prevent the cancer from coming back. It can also be used in combination with chemotherapy or as the main treatment in cases where surgery isn't an option.
Types of Radiation Therapy for Breast Cancer
External Beam Radiation Therapy (EBRT)
External beam radiation therapy (EBRT) is the most common type of radiation used to treat breast cancer. In this method, radiation is delivered from outside the body using a machine. It is typically used after breast-conserving surgery (lumpectomy) to reduce the risk of recurrence.
Process: The patient lies on a table while a machine called a linear accelerator targets the affected area with radiation.
Treatment Duration: The process typically lasts 5-7 weeks, with daily treatments.
Internal Radiation Therapy (Brachytherapy)
Brachytherapy involves placing a radioactive source inside the breast tissue near the site of the tumor. This method allows for higher doses of radiation to be delivered directly to the cancer cells while sparing nearby healthy tissue.
Types of Brachytherapy: There are two types: intracavitary and interstitial. Intracavitary involves placing radiation in a balloon inside the breast, while interstitial involves placing catheters directly into the tissue.
Duration: This method is usually quicker than external beam radiation, often completed in just a few days.
Proton Beam Therapy
Proton beam therapy is a newer form of radiation that uses protons rather than X-rays to kill cancer cells. Protons can deliver radiation more precisely, which may reduce damage to surrounding healthy tissues.
Precision: It is especially useful for patients with left-sided breast cancer, as it minimizes radiation exposure to the heart.
Availability: This therapy is not as widely available as EBRT and is typically used in specialized cancer centers.
How is Radiation Therapy Administered?
Planning the Treatment
Before radiation therapy begins, a treatment plan is created. The process involves:
Simulation: During this process, a CT scan is performed to map the exact location where radiation will be applied.
Custom Markers: The radiation oncologist may mark the skin with small tattoos to ensure precision in delivering radiation each session.
Daily Sessions
For external radiation, sessions typically last only a few minutes, though setup time may take longer. Patients lie still while the machine delivers the radiation beams.
No Pain During the Treatment: The actual radiation therapy is painless, but staying still during the session is crucial.
Follow-Up Appointments
After completing radiation therapy, follow-up appointments with your oncologist will monitor how well the cancer has responded and manage any side effects.
Common Side Effects of Radiation Therapy
Skin Irritation
One of the most common side effects of radiation is skin irritation in the treated area. This can include redness, itching, or peeling, similar to a sunburn.
Management: Use mild soaps, avoid tight clothing, and apply recommended creams to soothe the skin.
Fatigue
Radiation can cause general fatigue that might worsen as treatment progresses. Many patients report feeling extremely tired even after light activity.
Management: Rest when necessary, but light physical activity, such as walking, can help maintain energy levels.
Breast Swelling
Some patients experience swelling or tenderness in the treated breast area. This usually subsides after treatment but can be uncomfortable during the therapy period.
Management: Wearing a supportive bra and avoiding underwires can reduce discomfort.
Changes in Breast Size or Shape
In some cases, radiation may affect the size or shape of the breast. This is more common after lumpectomy, where part of the breast tissue has already been removed.
Rare Long-Term Effects
In rare cases, radiation can cause long-term changes, including damage to the ribs, heart, or lungs, especially if the left breast is treated.
Minimization: Advanced techniques such as deep inspiration breath-hold (DIBH) are used to reduce these risks.
What to Expect During Radiation Therapy
Pre-Treatment Preparation
Before radiation begins, you'll meet with a radiation oncologist who will explain the treatment plan, and perform a simulation to mark the treatment area.
The Treatment Process
For external radiation, each treatment session is quick, but you'll need to commit to daily appointments for several weeks. Each session lasts about 15-30 minutes.
No Hospital Stay: Radiation is an outpatient treatment, meaning you can go home after each session.
Post-Treatment Recovery
After completing radiation therapy, you may still experience some side effects, such as fatigue and skin irritation. These usually subside within a few weeks to months.
Monitoring: Regular follow-up visits with your healthcare team will be necessary to monitor your progress and address any ongoing side effects.
When is Radiation Therapy Not Recommended?
During Pregnancy
Radiation is generally not recommended for pregnant women due to the risk it poses to the developing fetus.
Patients with Certain Health Conditions
Patients with underlying heart or lung conditions may be advised against radiation therapy if it could worsen their health issues.
Advantages of Radiation Therapy for Breast Cancer
Non-invasive: Radiation therapy is a non-invasive treatment compared to surgery.
Precision: Modern radiation techniques allow for precise targeting of cancer cells, sparing healthy tissues.
Effectiveness: It has proven to be effective in reducing cancer recurrence after surgery.
Conclusion
Radiation therapy plays a crucial role in the treatment of breast cancer, especially after surgery. With various types available, each tailored to specific needs, it provides a highly effective method to destroy cancer cells while minimizing damage to healthy tissues. Understanding the side effects and the process can help patients feel more prepared and empowered throughout their treatment journey.
FAQs About Radiation Therapy
Is radiation therapy painful?
No, the radiation therapy itself is painless. However, you may experience some discomfort from side effects such as skin irritation and swelling.
How long does radiation therapy take?
Treatment sessions are usually brief, around 15-30 minutes, but you'll need daily treatments over several weeks.
Can I continue working during radiation therapy?
Many patients continue to work during radiation therapy, but fatigue may require you to reduce your hours or take breaks.
Are there long-term risks associated with radiation therapy?
Long-term risks are rare but can include damage to nearby organs like the heart and lungs. Modern techniques aim to minimize these risks.
Will I lose my hair from radiation therapy for breast cancer?
Hair loss only occurs in the area being treated. Since radiation for breast cancer targets the breast, it won't cause hair loss on your head.
