Red blood cells contain hemoglobin, which carries oxygen from your lungs through your body. Chemotherapy (chemo) can affect your red blood cells. If you have fewer red blood cells, a reduced amount of oxygen circulates through your body and you can become anemic. Anemia can make you feel very tired. It may also cause problems with your heart, brain, and nerves.
Chemo is not the only possible cause. Anemia can also be caused by:
- Blood loss
- Kidney disease
- Vitamin or iron deficiencies
- The cancer itself
- Shortness of breath
- Pale skin
- Rapid heartbeat
You may not realize that you're anemic because the symptoms can be mild or even go unnoticed. But the symptoms could get worse as you become more anemic. Left untreated, anemia can cause many problems, including:
- Heart problems
- Nerve damage
- Impaired mental function
If you do become anemic, your doctor may prescribe iron or other supplements. Your doctor may talk with you about medicines to prevent anemia. If your anemia symptoms become severe, you may need a blood transfusion. There is a small risk of infection or allergic-type reactions with transfusions. As with all treatments, speak with your doctor and healthcare team about the risks and benefits of each of these treatments.
Speaking With Your Doctor
It's important to talk to your doctor and care team about your risk of developing anemia. The following questions are a great way to start a dialogue with your doctor.

A Closer Look: Virginia*
|Virginia is a 52-year-old bank executive diagnosed with stage II breast cancer. Her doctor has placed her on an aggressive chemo treatment plan.|
|She responds well to chemo that is known to be myelosuppressive, which means it decreases the bone marrow activity that creates new blood cells.|
|During her course of chemo, Virginia tells her doctor she has been feeling short of breath and fatigued. Her doctor tells her these are common side effects of chemo.|
|Virginia's fatigue persists. Tests show that her red blood cell counts are low. She is diagnosed with mild anemia.|
|Her doctor orders supplemental iron to increase her levels of red blood cells.|
