In a study done at Stanford University, the team managed to target cancer cells. With all the breakthroughs that I hear of lately, I think there's room for cautious hope about the disease.
The article, Nanotube-Laser Combo Selectively Targets Cancer Cells, Study Shows, published in Scientific American is very encouraging:

"One of the longstanding problems in medicine is how to cure cancer without harming normal body tissue," notes study co-author Hongjie Dai. Thus, to ensure that the carbon nanotubes were attracted only to diseased cells, the researchers coated them with folate molecules. The team then shined a flashlight-size near-infrared laser on aqueous solutions of both tumor and normal cells. Although harmless to regular cells, the light heated the nanotubes to 70 degrees Celsius within two minutes, killing the cancer cells they had invaded.
