Hi Heng,
Firstly I just wanted to say welcome - I am glad you found your way to the online network and I hope it helps both you and your mum to connect in with others who have been diagnosed with breast cancer.
It looks like some of the ladies have already offered some of their own experiences.
A couple of things that might help as well - you and your mum could connect in with the online support group - 'Asian Women with BC and supporters and friends' you might want to request contact with some of the Chinese members and ask them questions.
Or there is some information on Cancer Australia's website written in Chinese which could help - http://canceraustralia.gov.au/publications-resources/cancer-australia-publications/information-women-early-breast-cancer-chinese
I hope that some other women will be able to jump in and offer some ideas as well.
