It’s been more than 30 years since a disease now called AIDS was first recognized in the United States. Back then, it was considered a death sentence. No treatments were available, its cause was unknown, and people often died within a few months after being diagnosed. Today, people infected with HIV—the virus that causes AIDS—can live full, healthy lives, in large part because of medicines and other discoveries made with NIH support.

For surgeons, removing a tumor is a balancing act. Cut out too much and you risk removing healthy tissues that have important functions. Remove too little and you may leave behind cancer cells that could grow back into a tumor over time. NIH-funded researchers are developing new technologies to help surgeons determine exactly where tumors end and healthy tissue begins. Their ultimate goal is to make surgery for cancer patients safer and more effective.
