I think that my distress in being diagnosed with, and acceptance of, BC lay in the change of treatment especially when reading Cancer Australia guidelines for breast cancer treatment is that radiation after a lumpectomy for a high grade breast tumour is the gold standard.
I felt ( and still do) that I did not receive the best of treatment. The breast surgeon was not the most approachable of surgeons.
However I do have radiation to use should I have a recurrence and that is a blessing.
As for the holiday, well unfortunately I needed to make a decision with the tour company regarding the final payment for the tour within 10 days of diagnosis. I had travel insurance and had no dramas claiming the cancellation.
What would I do differently? Delay treatment until after a holiday, however at the time I followed faithfully the advice of the medicos. Next time, they wait!
