Does breast cancer always make you feel fatigued?
Fatigue is extremely common with breast cancer—about 90 percent of people experience it during treatment. However, it doesn't affect everyone the same way or all the time.
The exhaustion you're feeling is real and different from normal tiredness. Cancer-related fatigue is severe and overwhelming. It doesn't improve with rest or sleep, which can be incredibly frustrating.
Many things contribute to this fatigue:
* The cancer itself
* Treatments like chemotherapy, radiation, and surgery
* Medications including hormone therapy and painkillers
* Emotional stress from managing your diagnosis
* Depression and anxiety
* Other health conditions
A MyBCTeam member shared, "I feel so beat out after treatments. It takes a lot to just take a shower or brush my teeth."
The good news is that fatigue can be managed. Talk with your care team about what you're experiencing. They can help identify specific causes and develop strategies to help you feel better, whether through light exercise, better sleep habits, addressing depression, or adjusting medications.
You're not alone in feeling this way, and it doesn't mean you'll always feel this exhausted.
