The New York Times and various life science researchers announced yesterday that we've improved our genetic map of breast cancer --
In a highly technical article published online in Nature, researchers identified four different genetic types of breast cancer
- Luminal A, a less aggressive, estrogen-positive cancer
B, a more aggressive, estrogen-positive cancer
- HER2-enriched, which
includes many, but not all, HER2-positive
- Basal (cell) -like, which includes many, but not all, triple-negative tumors
Now it needs to move from the bench (laboratory) to the bedside (clinical usefulness). Karuna Jaggar, executive director of Breast Cancer Action, called it a "stay tuned story" as we wait to learn which therapies turn out to work well in the real world.
