LYLE ALZADO used to be a rough, tough -- emphasis on tough, by his own admission and boast -- defensive end with the NFL Raiders. Today, having "used a certain steroid" in trying for a comeback with the Raiders last year, he has an inoperable brain tumor. That sounds a loud alarm bell.
Alzado's belief that the steroid brought on the tumor has some medical backing. Dr. Forest Tennant, the NFL's former drug adviser, told the Associated Press: "Anabolic steroids depress the immune system and lymphocytes. He (Alzado) has lymphoma. You don't have to be a rocket scientist to figure out the connection."
There are a lot of athletes -- and not just professional football players -- who should pay close attention to that alarm bell.
