All his life, he slept like a stone. But now, there's an annoying trip to the bathroom every night, sometimes once or twice a night. For most men, these nightly bathroom runs may be the first sign of an enlarged prostate. Other symptoms may include trouble starting a stream of urine, leaking, or dribbling. And, like gray hair, an enlarged prostate is a natural by-product of getting older, doctors say.
For almost all cancers (such as breast, brain, prostate, and lung), a person may donate blood five years after diagnosis or date of the last surgery, last chemotherapy or last radiation treatment. For blood cancers (such as leukemia or lymphoma), a person is not allowed to donate blood.
You may donate whole blood once every 56 days, which allows plenty of time for your red cells to be replenished. Platelet (apheresis) donors may donate more frequently -- as often as once every seven days and up to 24 times per year. This is because the body replenishes platelets and plasma more quickly than red cells. Platelets will return to normal levels within about 72 hours of donating.
