Abortion drug RU-486 prevents from breast cancer

New studies show that the abortion drug RU-486 prevents from breast cancer in carrying a dangerous “cancer gene” mutation. But this drug does not mean a total prevention from breast cancer and is not meant for long time uses. The scientists said that the cancer-preventing effects are in the stem from the drug's ability to block progesterone, a major sex hormone.

The professor of biological chemistry and cell biology at the University of California Irvine said “So new, safer progesterone-blocking drugs are on the way to treat women with the BRCA1 gene mutations linked to breast cancer, says Eva Y.-H. P. Lee, PhD”

Some women who are BRCA1 carriers suffer a lot and have to go through hard ways to prevent cancer such as having very traumatic surgery on their ovaries and both breasts are removed. A lot of these women have asked about clinical use of RU-486, but it would have too many side effects for prevention use. However it's important to mention that for the past three years there have been companies working on more appropriate anti-progesterone drugs.

Every cell in the body carries BRCA1 genes, which are involved in DNA repair. And breast cancer strikes between 36% and 85% of women with mutations in the BRCA1 gene, or in a second gene, BRCA2. These women also face a 16% to 60% chance of ovarian cancer, while it has never been clear why mutant, inactive versions of the gene are linked mostly to breast and ovarian cancer.
