A team of Portuguese scientists have published a study that elucidates the role of the hormone progesterone in breast cancer. According to their findings, progesterone has a role in angiogenisis, the formation of blood vessels, adjacent to the tumor. The supply of nutrients to cancer cells is crucial to their progession, without a nutrient supply the cancer cells will die.

70% to 80% of breast cancer tumors show estrogen and/or progesterone receptors in their cells. Anti-hormonal therapy is used with good results, often with greater effectiveness than chemotherapy.

The study is being published in the “Journal of Cellular Biochemistry”.
