Can steroids lead to brain cancer?

Norm Fost, the professor of Wisconsin’s University, claims about several common misconceptions linked with anabolic steroids. Although some specialists proclaim about dangerous and even life-threatening side results of anabolic steroids, Dr. Fost denies these affirmations, claiming that they lack any scientific basis.
But affirmations of this specialist are not so frequently quoted by media as affirmations about severe side reactions of steroids.  Thus, the message of Norm Fost that steroids aren’t so harmful, as it is believed, is noted once for every 500-time conclusion that steroids represent a real evil.
 Furthermore, editors usually create a wrong perception among readers, writing the quotes of this specialist incorrectly. 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 well-known that these preparations can cause different side reactions. Norm fost doesn’t deny risks of occurring  unwanted consequences. Actually, this specialist says some other things. He notes that probable risks of steroids are significantly exaggerated. Norm Fost denies the statement that steroids cause the rare type of brain cancer. According to several sources, this caused 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 blamed his prolonged steroid abuse for the primary brain lymphoma that finally led to his death. Assertion of this player was the only evidence which supported the link between his intake of steroids and the brain cancer.
But a question appears here. Why did Alzado make public his steroid use, blaming anabolic steroids for his diseases? Couldn’t you find this aspect strange?
Actually, it was said that AIDS had affected his immune system and promoted destroying his body by the primary brain lymphoma.
A pathologist noticed that Lyle Alzado had had T-cell lymphoma that was related to AIDS. According to Dr. Thomas DeLoughery, Alzado was afraid that the public would proclaim 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 linked with HIV or AIDS.
The doctor DeLoughery explained the case. He noticed 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 which Alzado had, no one of them confirmed about links between his brain lymphoma and intake of steroids.
