Breast Cancer Vaccine on the Horizon

Women over 40Cleveland Clinic researchers report promising results with the development of a vaccine that may not only treat, but prevent breast cancer. Dr. Vincent Tuohy and his team have worked for the last eight years, testing a potential vaccine for breast cancer.

The single vaccination prevents breast cancer tumors from forming and also stops the growth of existing tumors, according to the researchers.  The drug makes the immune system attack a particular protein found in most breast cancer cells and in the mammary tissues of breastfeeding women.

To date the treatment has only been tested on mice, but these results have been ”overwhelmingly favorable”  according to Dr. Tuohy,  an immunologist at the Cleveland Clinic’s Lerner Research Institute, in an article by Fox News.  “If it works in humans the way it works in mice, this will be monumental,” he said.

Clinical trials on women are planned to begin next year, but it may be as long as 10 years before the vaccine is available.
