Here's good news concerning the ongoing search for cures for cancer:
South Korean [scientists] have said they have developed a new genetically altered strain of virus which is highly efficient in targeting and killing cancer cells. The new therapy developed by the team from Yonsei University uses a genetically-engineered form of the adenovirus, which normally causes colds. When injected into cancerous tumors, the virus quickly multiplies in the cancer cells and kills them, the team said.
The new adenovirus can target only cancer cells and does not harm normal cells. Following three rounds of injections, more than 90 percent of cancer cells in the brains, liver, lungs and womb of mice disappeared within 60 days.
There are still many more tests to be done and treatment for humans is probably several years away, but this certainly sounds on the face of it like a wonderful breakthrough.
