Hi @Ali78
Sorry to hear about your diagnosis - it can be a very stressful time, but you might feel better once you have seen your specialists and have a plan forward. The type of breast cancer will inform your treatment, so you should know more once some pathology is done. You may have access to a breast cancer nurse, which is an awesome support for queries/discussion.
I was a similar age to you (47) at diagnosis. I continued to work part-time through most of my treatment (which was chemo, surgery & targeted therapy), because I wanted to maintain some sort of routine and normalcy and also because it was possible with my kind of work. However, I know other women who took extended time off work.
I also continued most of my exercise/sport, although modified depending on how I felt and what my oncologist recommended (ie not competing and not putting my head in the swimming pool due to infection potential).
Not sure if you have family/kids. I have two teenagers, so we decided to tell them straight away and let them know that they could talk to their friends or a counsellor about it (for support). We also let their school know. My husband came to appointments and took notes which was great because it is really hard to take in information, particularly in the early period.
All the best xx
