Breast Cancer Vaccine Shows Promising Results
by Jeanette: MyFreeImplants on June 3rd, 2010A vaccine to prevent breast cancer is showing promising signs in animals, according to a study by researchers at Cleveland Clinic’s Lerner Research Institute.
The scientists found that a single vaccination with the antigen a-lactalbumin prevents breast cancer tumors from forming in mice, and also inhibits the growth of existing tumors.
If successful, this would be the first vaccine to prevent breast cancer. Though the researchers are optimistic, they warn that there is no guarantee that the same results in animals will occur in humans, and it’s possible that the treatment will not make it to human trials.
The current study tested genetically cancer-prone mice – half received a vaccine containing the antigen and half received a vaccine that did not contain the antigen. None of the mice vaccinated with the antigen developed breast cancer, while all of the other mice did.
Currently two cancer-prevention vaccines have been approved by the FDA: cervical and liver cancer. However, these vaccines target viruses, while the breast cancer vaccine being tested targets cancer formation.
If human testing proves successful, the strategy would be to vaccinate women over 40, as well as young women with a heightened risk of breast cancer.
Vincent Tuohy, Ph.D., the study’s principal investigator and an immunologist at the Lerner Institute says that there is no funding for human trials at this point, but it has been applied for.
