"Please take time to look at your boobs. It could save you're life."
Her proud husband Craig Thomas Royle described his wife as an "inspiration" and said "together we can make people aware and kick cancers ass."
Following Lisa's surgery her posted again saying she was "doing really well."

Sister Claire Osmand has set up a 'Wig Fund' web page for Lisa, saying that as well as losing her breast "she certainly doesn't deserve to loose her bloody hair as well."
She said: Lisa has done a bloody great job of raising awareness about looking at your boobs the least we can do is help to get her a nice wig/bra and maybe some spending money for her Florida 2016 holiday which I know she is focussing on.
"If everyone of the 15,000 people who saw that photo gave 1p each that would be fabulous!!! A big ask and I don't know if this is the right thing to do, but I'm doing it anyway, because like I said I feel useless!!"
The post has received more than 30,000 likes from well wishers on Facebook - with dozens posting messages praising Lisa for her bravery.
