Can hiv increase my chances of cancer?

Potentially: Poorly controlled HIV results in a condition where your own immune system is not capable of fighting off even common viruses and bacteria. Part of the normal function of the immune system is to kill cancerous cells in the body. So yes, HIV can increase your change of cancer in the long-term.

The answer used: To be a simple yes. Now it actually seems to be no. Low cd-4 counts and high viral loads still are risks in brain lymoma, nhl, anal cancers, but with 'normal" cd-4 and undetectable viral loads, there appears to be little difference. Treatment is hazardous with low counts, but not different with normal cd-4. Hiv treatment was also suspected as causative, has not proven out.
