Did Lyle Alzado die because of steroid abuse?

The professor of Wisconsin’s University Norm Fost claims about some common misconceptions linked with anabolic steroids. Although certain specialists proclaim about dangerous and even fatal unwanted reactions of anabolic steroids, the physician Fost denies these statements, claiming that they don’t have any scientific basis.
But statements of Norm Fost are not so frequently quoted by media as statements about severe adverse symptoms of steroids.  So, the message of Norm Fost that steroids are not so harmful, as it is believed, is noticed once for every 500-time affirmation that steroids represent a real evil.
 Furthermore, editors usually mislead readers, writing the quotes of this expert wrongly. For example, a headline of a radio talk sounds following: “UW-Madison doctor: steroids aren’t harmful at all”. The headline is wrong. It is misleading. Norm Fost has never confirmed that steroids were not harmful at all. It is obvious that these products can cause various undesirable symptoms. Norm doesn’t deny probability of occurring  undesirable consequences. In fact, this physician says some other things. This physician notes that probable risks of steroids are significantly exaggerated. This expert denies the statement that steroids cause the rare type of brain cancer. According to some sources, this led to the death of Lyle Alzado, a player of the NFL. Dr. Fost notes that there is no any connection between the death of this player and steroids.
Alzado demonized his prolonged steroid abuse for the primary brain lymphoma which finally led to his death. Assertion of this player was the only evidence which supported the link between his steroid use and the brain cancer.
But a question appears here. Why did Lyle Alzado make public his steroid use, demonizing anabolic steroids for his illness? Couldn’t you find this factor strange?
In fact, it was said that AIDS had affected his immune system and induced destructing his body by the primary brain lymphoma.
A pathologist noted that Alzado had had T-cell lymphoma that was linked with AIDS. According to Dr. Thomas DeLoughery, Alzado was afraid that the public would know that he died from AIDS because of the cancer.
Pathologists at OHSU reported that this football player had had B-cell lymphoma which was not connected with HIV or AIDS.
The doctor DeLoughery explained the case. He noted that T-cells of this person were inflamed but the malignant cells were B-cells.
While specialists disputed about AIDS and the type of cancer that Lyle Alzado had, nobody of them noted about links between his brain lymphoma and intake of steroids.
