Investigating the Mystery of Cancer-Related Fatigue

Investigating the Mystery of Cancer-Related Fatigue


>>Delia: Hi. My name is Delia, and I’m a graduate student
at the National Institutes of Health. I’m also a nurse and I work
with many cancer patients. While most of them beat their disease
and end up completely free of symptoms, about a third of the patients continue
to feel tired for months or years after the treatment has ended, a
condition we call cancer-related fatigue. Fatigue makes it hard for them to
complete everyday tasks or hold down a job. I am trying to figure out what causes
cancer-related fatigue by studying the blood from former cancer patients, some
of whom still live with fatigue. I’m especially interested whether tiny
sacs called extracellular vesicles that carry materials from one cell to
another can explain cancer-related fatigue. Answering this question will help doctors and
nurses like myself predict which patients are at risk for cancer-related fatigue
and could develop treatments that can help them to gain the energy back.
