HRA Screening Is Most Cost-Effective for HIV-Positive Men
In late 2010, results from a Canadian study showed that using HRA, or high resolution anoscopy, is the most cost-effective way to screen for anal cancer. With HRA, a doctor uses a small camera called an anoscope to look at and take a tissue sample from the anus to later screen for cancerous cells.

This is due to infection with HPV, or the human papillomavirus. As well, HIV-positive men who have sex with men (MSM) have much higher rates of anal cancer ... up to 160 times higher.
