Yes: unfortunately, your immune system most likely will not be running at 100% effectiveness if you are sleep deprived. It is possible that you could have a dormant E.Barr infection that is asymptomatic, but the only way to know that would be to ask your Dr for a lab test. Lack of sleep isn't the greatest risk for cancer - poor diet and lack of exercise, smoking, alcohol, are all bigger risks.
