I know you don't believe that HIV leads to AIDS, and that it only lowers CD4 counts, but what if someone has HIV and they do nothing about it? Does it lead to lymphomas or leave people susceptible to immune issues in the future?
The problem is that HIV cannot cause AIDS under the original definition of AIDS. The definition of AIDS was changed back in the early 80s to fit the HIV virus since Gallo, who had already been busted for scientific fraud, lied to the world again with his claim that HIV caused AIDS. So the government had to find a way to cover up his lie. So they changed the definition of AIDS to fit the virus. By adding the drop in CD4 counts they could now honestly claim that HIV could cause AIDS.
But the original definition of AIDS did not include leukemias and lymphomas. The original definition was testing positive and developing the opportunistic infections Kaposi's sarcoma, which is a different cancer with both viral and bacterial origins, and pneumocystis carinii pneumonia.
Since HIV is a cancer virus it can potentially cause cancer, but again the person would have to immune suppressed sufficiently to allow the virus to do this. And a healthy immune system can easily fight off the virus before it can take hold. This is one of the over 65 reasons for false positives on HIV tests.
This brings up another point. There are NO standard lab tests than can confirm the presence of HIV or any other virus. Antibody tests nor polymerase chain reaction (PCR, "viral load") do not prove the presence or activity of any particular virus. These are more sales tools than anything.
