Hi KatyJoy - glad you've found the forum and hopefully we can help you through and more importantly I do hope your journey doesn't have too many twists and turns.
You are so right the diagnosis is Breast Cancer but the treatments for all of us are differing. I found my Breast Care Nurse the best source of information when I was unsure of something.
One of the things that will help you feel good about yourself as you go through this wretched journey is the Look Good Feel Better program
https://lgfb.org.au/They are run all over Australia and there is bound to be one near you. They help not only with make up and well being but hair loss, types of wigs, perhaps where to access near you, how to wear a scarf that makes you feel good! It is a good thing to do with like people!
Wishing you all the best, Take care
