Cancer Subtypes
My cancer was HR- HER2+ which means the Hormone Receptors (HR) of estrogen and progesterone were not present on the cancer cells (-) but the HER2 protein was (+). This is the rarest combination, but not the hardest to treat. The HER2 protein makes the cancer very aggressive and spread quickly, but there are targeted therapy drugs that can treat it. Triple Negative (none of the three) is the hardest to treat because there is nothing to target.
