"Eventually, one way or another, we will get much better communications, so it's just a question of when are we going to try again," Tzanetos said.

June 1 (UPI) -- An antifungal medication commonly prescribed to treat toenail infections helped eliminate dormant cells within bowel tumors in mice. Researchers at the Cancer Research UK Cambridge Institute found that itraconazole effectively halts the growth and progression of certain types of colorectal cancer. Their findings were published Thursday in the Journal of Experimental Medicine. "This innovative study has taken a step toward addressing one of the biggest challenges in cancer research," Dr. Greg Hannon, director of the institute, said in a press release. "Tumors are made up of many different types of cancer cells, which can evolve separately and respond to treatments differently." Colorectal cancer of the colon and rectum is the second leading cancer killer in the United Stat...
