Frequently Asked Questions

At Evansville Cancer Center, our mission is to provide superior treatment and compassionate care for those facing cancer. If you’ve been diagnosed with cancer and referred to radiation therapy, you likely have many questions. Below, we’ve answered some of the common questions we hear from our patients to help you feel informed and supported.

Are radiation therapy and chemotherapy the same?

No. Radiation therapy and chemotherapy are two distinct modalities used in the treatment of cancer, often employed in conjunction to maximize therapeutic outcomes.

Chemotherapy involves the administration of specific drugs designed to target and eliminate cancer cells throughout the body. These drugs can be delivered orally, via injection, or intravenously. Chemotherapy is particularly effective for treating cancers that have the potential to metastasize, as it circulates through the bloodstream to reach cancer cells wherever they may be.

Radiation therapy, in contrast, utilizes high-energy rays, such as X-rays, to focus on and destroy cancer cells at a specific site. This localized treatment is especially beneficial for targeting tumors that are confined to one area, allowing for precise delivery of therapeutic doses to the affected region.

Both therapies aim to control or eradicate cancer, and the choice of treatment is tailored to the individual patient’s type of cancer and the extent of its progression. By combining these therapies, healthcare providers can offer a comprehensive approach to cancer treatment, balancing systemic and localized strategies for optimal patient care.

What is the difference between IGRT and IMRT?

Image-Guided Radiation Therapy (IGRT) and Intensity-Modulated Radiation Therapy (IMRT) are both advanced forms of radiation therapy used to treat cancer, but they have distinct differences in how they target tumors and protect surrounding healthy tissues.

IMRT is a sophisticated radiation technique that uses computer-controlled linear accelerators to deliver precise radiation doses that conform to the three-dimensional shape of the tumor. This method allows for the modulation of the radiation beam’s intensity, enabling higher doses to be delivered directly to the tumor while minimizing exposure to adjacent healthy tissues. This precision reduces the side effects of treatment and improves the likelihood of effectively targeting the cancerous cells.

IGRT, on the other hand, enhances the precision of radiation therapy by incorporating imaging technology during treatment sessions. Tumors can shift position between treatments due to factors like breathing or changes in the patient’s positioning. IGRT addresses this by using real-time imaging, such as Cone-Beam CT, to accurately track the tumor’s location and adjust the radiation beams accordingly. This ensures that radiation is delivered with optimal accuracy, making the treatment more effective and safer.

What are the side effects of radiation therapy?

While highly effective in controlling cancer, radiation therapy can sometimes affect healthy cells in the surrounding area, leading to potential side effects. These side effects can vary depending on the location and dosage of radiation, as well as individual patient factors. At our cancer center, we prioritize personalized care and ensure that each patient collaborates with a comprehensive care team. Together, we will discuss potential side effects relevant to your specific treatment plan and develop strategies to minimize their impact. Our goal is to enhance your comfort and quality of life throughout your treatment journey.

Our dedicated team is committed to supporting you at every stage, providing guidance and care tailored to your unique needs.

How long does it take to recover from radiation therapy?

Recovery from radiation therapy is a unique journey for each individual, influenced by factors like the type of radiation and the area treated. Many patients find that side effects, if they occur, often start during treatment and may peak shortly after it concludes. However, these effects typically begin to improve within a few weeks to a couple of months.

Most people gradually return to their usual routines, often feeling more like themselves as time goes on. While some side effects might linger a bit longer, healthcare providers are there to support and manage any ongoing concerns.

Regular follow-up appointments are an excellent way to ensure your recovery is on track and to address any questions or needs you may have. Remember, your care team is dedicated to helping you every step of the way, making your path to recovery as smooth and positive as possible.

Is it safe to be around someone receiving radiation therapy?

Radiation therapy is a widely used and effective treatment for various types of cancer, but many patients worry about how radiation therapy might affect their caregivers, children, or pets.

The type of radiation therapy a patient receives determines whether or not they pose any risk to others. For patients undergoing external beam radiation therapy, such as those treatments offered by Evansville Cancer Center, there is no radiation left in the body after treatment, making it completely safe for them to be around others immediately following their sessions. These patients do not become radioactive, so they can safely interact with family, friends, and caregivers without any risk of radiation exposure.

How long does a typical radiation therapy session last?

Each session usually lasts about 15 to 30 minutes, although the actual time spent receiving radiation is only a few minutes.

How many sessions of radiation therapy will I need?

The number of sessions varies depending on the type and stage of cancer, as well as the individualized treatment plan designed by your oncologist.

Will I feel anything during the radiation therapy session?

Most patients do not feel anything during the treatment itself, although the machine may make noise.

Can I continue my normal activities during radiation therapy?

For many patients, maintaining a sense of normalcy is important during treatment, and the good news is that many people are able to continue with their usual activities while undergoing radiation therapy. However, there are a few considerations to keep in mind:

  1. Listen to Your Body: Radiation therapy can cause fatigue, so it’s important to pay attention to how you feel and rest when needed. You might find that you tire more easily, so pacing yourself and taking breaks can be beneficial.
  2. Adjusting Your Routine: While some patients continue working and engaging in hobbies, adjustments might be necessary. For instance, if your job is physically demanding, you may need to modify your workload or schedule to accommodate treatment and recovery.
  3. Exercise and Physical Activity: Light exercise, such as walking or gentle stretching, can actually help boost your energy levels and improve your mood. Always consult with your healthcare provider before starting or continuing an exercise regimen during treatment.
  4. Social Activities: Maintaining social connections is important for emotional well-being. Feel free to continue socializing with friends and family, but be mindful of your energy levels and any side effects you may be experiencing.
  5. Diet and Nutrition: A balanced diet can support your overall health during treatment. Eating nutritious meals can help manage fatigue and other side effects, your care team will work with you on any specific dietary changes if necessary for your treatment.
  6. Work and School: Many patients continue working or attending school during radiation therapy. It’s helpful to communicate with your employer or educational institution about your treatment schedule to make any necessary accommodations.
  7. Travel and Leisure: While travel is generally safe, it’s a good idea to discuss any plans with your healthcare team, especially if your treatment schedule might be affected.

Ultimately, the key is to find a balance that works for you. Your healthcare team is there to support you, so don’t hesitate to reach out for advice or assistance in managing your daily activities during radiation therapy.

How should I care for myself during radiation therapy?

It’s important to follow your healthcare provider’s advice, which may include staying hydrated, maintaining a balanced diet, and caring for your skin in the treated area.

How will I know if the treatment is working?

Your doctor will monitor your progress through follow-up appointments and imaging tests to assess how well the cancer is responding to treatment.
