While not all breast cancer patients receive radiation therapy it is a common component of breast cancer treatment. In some cases radiation is used alone and in others cases it is combined with additional therapies. Knowing what side effects are associated with radiation can help you prepare for your treatment and can make experiencing those side effects less scary.

Skin changes

One of the main side effects of external radiations is changes in the skin. These changes can occur gradually throughout treatment and some may last for months or years after treatment. You may experience the following changes that feel and look similar to a sunburn:

How to cope

If you are struggling with skin changes during or after treatment there are a few steps you can take to increase your comfort levels and to help heal your skin.

Fatigue

A 2020 study uncovered that between 62% and 85% of people undergoing cancer treatment report experiencing cancer-related fatigue. While there is no specific treatment your doctor can give you for fatigue, they can help you come up with a plan for combating it. Fatigue is a much greater issue than simply feeling tired and taking a nap or getting a good night’s rest often isn’t enough to overcome it.

Signs of fatigue include:

How to cope

To cope with fatigue you can try the following tactics.

Heart or lung problems

Unfortunately, some patients experience lung inflammation for years after undergoing radiation therapy. Especially if they also went through chemotherapy treatment. In the event of left breast radiation, heart injuries can also occur and can lead to heart disease or conditions.

How to cope

Your doctor is key here and will help you develop a treatment plan that will reduce your risk for heart or lung problems. For example, to avoid injuring the heart or lungs, lying on your stomach instead of your back and allowing the treated breast to hang through a hole in the treatment table can reduce exposure for both your heart and lungs.

Lymphedema

According to the Journal of Clinical Oncology as many as 83% of breast cancer patients can experience lymphedema. Lymphedema is a medical condition caused by disruption or damage that occurs to someone’s lymphatic structures such as lymph nodes or lymph vessels. The lymphatic system cleans, filters, and processes protein rich fluid and when that fluid becomes stagnant, it can back up and lead to tightness, swelling, and discomfort.

Lymphedema symptoms can arise years after receiving radiation therapy and are caused by scarring and blockages. These symptoms can include:

How to cope

You should have a plan in place with your doctor to reduce the risk of lymphedema ever occurring and you should both be looking for any signs of it arising. Catching lymphedema early and receiving treatment for it is the best way to stop this condition from worsening. If you experience any swelling in your hand, arms, or joints, or have trouble with mobility alert your doctor right away.

To help avoid lymphedema from occurring or worsening you can:

The takeaway

Radiation is a common component of breast cancer treatment plans. While it does have some challenging side effects, there are steps you can take to manage them to find some relief during and after treatment. You can talk to your doctor and care team before and during treatment about possible radiation side effects you can expect, how to reduce the risk of developing those side effects, and how to manage them if they arise.

Tracking symptoms related to radiation, or any part of your treatment, can help you and your doctor understand their frequency and severity.
