so nice of you! how effective is it to treat cancer....?
my late dad was a qualified non-practicing 中医师. he once asked me to look for a plant from his kampung that was used to treat cancer....
that was so many years ago and i already forgot what plant. looking back, it could be this plant......??    
i didn't manage to find for him...

According to a NUS research, it is helpful.

There could also be other plants your father is talking about. These are mentioned in the above news.

I grow so many so that my family members can chew on one raw leaf a day. I also have 'black face general' which I use to brew once a week to drink. But not recommended for women to drink this as it's very cooling.

If you want I can give you some cuttings. Or you could join those gardening groups in facebook and ask for it also.
