You are right and I mis-wrote with the word hormone. However, in healing, more human epithethal growth regulator (protein) is produced. The Her 2 positive breast cancer has the receptors on it that responds to the growth regulator. More protein, more can bind (except if Herceptin is nicely attached to those receptors and blocking the attachment). So, theoretically, surgery can cause growth but not spread (if this is even true at all). Also, I think the protein is a hormone as a hormone is any substance that produces a specific effect on the activity of cells or produces a stimulatory effect on cellular activity. Some hormones can be proteins and some can be fats (or fatty substances - I did study for my MS in biochemistry studying lipid (fat) chemistry although enzymes is where its at and they are always proteins) . Oh well.
Best wishes
