Hi Adrienne... My cancer was OR/PR positive HER2 negative...
OR = oestrogen
PR = progesterone
The HER2 gene makes HER2 proteins. HER2 proteins are receptors on breast cells. Normally, HER2 receptors help control how a healthy breast cell grows, divides, and repairs itself. But in about 25% of breast cancers, the HER2 gene doesn't work correctly and makes too many copies of itself (known as HER2 gene amplification). All these extra HER2 genes tell breast cells to make too many HER2 receptors (HER2 protein overexpression). This makes breast cells grow and divide in an uncontrolled way.
do you have a breast care nurse yet? They are excellent at dissecting and explaining everything to you... Otherwise always ask a million questions of your dr and oncologist! Ask until you are satisfied you understand .... Wishing you all the best xx
