The Risks of Cancer-Related Anemia

You don't have to be bone-tired during treatment.

Nearly everyone expects to feel tired during cancer treatment; after all, cancer-related fatigue affects 76% of patients. But most people don't realize that fatigue is often caused by a treatable condition: anemia .

"I felt like I was moving underwater," recalls Peggy B., a 48-year-old breast cancer survivor, who became anemic during chemotherapy. "You know that feeling? That feeling of resistance along every limb you try to move?"

In simplest terms, anemia develops when you no longer have enough red blood cells to carry oxygen to all the systems of your body. That oxygen sustains your energy. Thus, the first symptom of anemia is fatigue. Other symptoms include dizziness, inability to concentrate, loss of appetite, and even chest pain or rapid heartbeat.

While anemia is common and treatable, it's no minor concern. The resulting fatigue can leave people too tired to carry on daily activities, and it can lead to feelings of hopelessness or depression.

Ishmael Jaiyesimi, D.O., an oncologist at Beaumont Hospital in Royal Oak, Michigan, tells WebMD that almost all of his chemo patients become anemic. So, he checks their hemoglobin counts regularly and treats them before the anemia becomes seriously symptomatic. Women should have a count of 12-16 grams per deciliter of blood; men should have 14-18 grams per deciliter.
