Hi Carol, DITTO!!! Jan 8th.. the day i was diagnosed with breast cancer! I'm 3 sleeps away from my surgery (wide local excision with removal of sentinel nodes) I get what you mean about running into people. I work for a gp, and I was diagnosed while i was on holidays. My first day back was basically my boss getting me into a surgeon and all the while the patients are asking me how my christmas was... I'd like to respond by saying shit thank you, and yours? LOL
I find that I tell those I want to know, and figure the grapevine will take care of the rest. A friend who is a nurse sent me a lovely message after we'd caught up and i filled her in, asking what she should say, as i'm the third person to tell her that they have bc. I told her that when people say to me, "i'm so sorry" I immediately feel the need to make them feel better. I would rather they say, "well that sucks" But thats just me. I also decided that i would make a public journal on facebook. I've been involved with fundraising for 4 years for Girls Night in and such, so this was another way to get the word out there to the ladies to be vigilant with their health. I also get my female friends young and my age (i'm 50) to feel the lump so they see what its like, and understande how easily i nearly dismissed it (its quite small) Again, that me and how i'm handling my journey.
Find what works for you, what you're comfortable with. Anyone who doesnt like it can take a flying leap.
Good luck with your journey. We're all here for you.
