Hi
My diagnosis was rather sudden, and within 6 days I was having a lumpectomy, which eventuated in a mastectomy once the pathology results came back (another story).
Initially only my husband knew and a very close work colleague. I didn't tell my boss, as I was waiting until I knew exactly what I was dealing with. Once all the results came in and I had my first visit with the breast surgeon, I then shared with my boss; then went home and we told our kids, my parents and my sister. The next day we told my sisters-in-law (3) and that was it.
After the lumpectomy I then shared with 3 close friends, as that is when I discovered I needed a mastectomy and I truly needed their support and shoulder to cry on. I discussed with my boss whether to tell my colleagues and decided he would meet with them privately as a small group, inform them that I was absent from work and dealing with a FAMILY crisis (it's true as it wasn't just me dealing with all this) and that I had requested privacy - they could SMS/email but not call, as talking was just too difficult. This allowed me privacy and time to deal with my thoughts, emotions, recovery, appointments and the whole long list of things going on. I was glad not to be bombarded with questions and advice. But it was nice to read messages of well wishes, receive flowers and cards saying 'thinking of you'.
A week after the lumpectomy I had a full mastectomy (31/10/18) but am very fortunate that the lymph nodes were clear, and amazingly I don't need radiation or chemo, but am taking hormone blocker.
I have returned to work and was greeted with lots of 'great to see you' and 'nice to have you back' and that is it. I can honestly say that it's nice to have an area of my life that doesn't revolve around cancer for the moment. I am having weepy days, as the hormones are out of wack, some days I need to leave early as fatigue kicks in, but they never ask questions or pry, but they're always supportive by asking if they can help with my workload, etc.
I'm still considering whether to share what has happened, or to keep it private. Once the news it out there, you can't take it back. Be careful who you share with, take your time.
