懷疑自己得了乳腺癌，約了21號的memo和ultrasound, 好害怕！

I'd like to ask if anyone here knows a good breast cancer doctor in Toronto. My appointments are in princesses margarete  hospital. Does that mean I will be treated there too ? Do I need to look for doctor myself? Any info will be much appreciated!

Also do you know if there is any support group in Toronto for breast cancer patients that I can talk to?

Thanks a lot!
