Can one have swollen arms and pain after radiation therapy?

Question

Hello doctor,

I finished 28 rounds of radiation therapy for stage 2 breast cancer last week and am now experiencing concerning issues. My right arm is swollen, measuring four centimeters (cm) more than my left. The surgical site feels hot and looks red, and my body temperature reaches 100.2 degrees Fahrenheit (°F) every evening. My lymphedema therapist cannot see me for three weeks, and wearing a compression sleeve worsens the numbness. I am also experiencing shooting pain down my arm when lying flat is this normal after radiation therapy?

Additionally, my latest echocardiogram (ECHO) shows my ejection fraction (EF) has dropped from 62 percent to 48 percent. How worried should I be? What exercises are safe for me to do now?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concerns about the symptoms you are experiencing after completing radiation therapy. The four-centimeter (cm) difference in arm circumference is significant and may indicate lymphedema. The hot, red, and swollen surgical site, along with a low-grade fever (100.2 degrees Fahrenheit), may suggest an infection or inflammation. The numbness and shooting pain could be related to radiation-induced neuropathy or lymphedema.

Given the severity of your symptoms, consider seeking an urgent evaluation from a lymphedema specialist or a breast cancer rehabilitation program. Alternative compression options, such as a custom-fit compression sleeve or a compression wrap, may help manage the swelling. The decrease in ejection fraction (EF) from 62 percent to 48 percent is a concern, as it may indicate radiation-induced cardiotoxicity. Regular cardiac monitoring and follow-up appointments with your oncologist and cardiologist are crucial.

Before starting any exercise program, consult your oncologist and lymphedema therapist to ensure it is safe. Consider gentle exercises such as yoga, Pilates, or swimming, which can improve mobility and reduce lymphedema risk. Schedule an urgent lymphedema evaluation, follow up with your oncologist and cardiologist, and prioritize self-care and symptom management. If symptoms worsen, reach out to your healthcare team for further guidance. You are not alone in this journey; support is available to help you recover.

I hope this helps.

Thank you.
