Hi Patsy.
Yes I bet it's a shock just being handed that. I recall my horror when someone asked my ki67 rate. I thought...no idea...then read my report ...my rate was 69. High is considered above 20. My friend was freaking out hers was 10.
So yes it's not great. And yes the word metastases is scary. However breast surgeons and oncologist still refer to it as locally advanced and preserve that word of metasteses for stage 1V.
What knowing level 1 to 3 means for you is where radiotherapy will be. It will be targeting these areas...and they will get those little sneaky out micro invasions too. Most likely they will be doing a boost along the mastectomy scar. You can discuss this with the radiologist.
I know this all is sounding terrifying. But I kept looking at my niece in times of my fear. She was 32. 10 nodes positive out of 20. Her2 positive. She us now 14 years cancer free. It is possible. But ask all you need of your surgeon.
Let us know how it goes.
Take care. Kath x
