Hi, for two weeks i have been extremely tired. i sleep 8 hours and nap ans still am tired. i am a cna so my job is very demanding. could it be cancer?

Ca Not likely: Fatigue can be a symptom of malignancy, but other factors are more common. Depression, esp. around the holidays is poss. Stress due to the holidays, your job or family might be building up. A general check up with routine blood work by a primary care provider, even a visit to an "urgent care" for blood work, might be helpful in someone your age. Eating a healthy diet might help.
