Vital cancer surgery for my mum

This is me and my amazing mum Hayley she is 43 years old and the best mum anyone could wish for. In 2011 she was diagnosed with breast cancer, she fought it so hard and so bravely and thank god she survived it. But in May of this year she was diagnosed again with recurring breast cancer of the spine. The second time this disease has tried to take my mum away. I'm trying so hard not to cry as I write this because she'll always, always say she's okay but I know she's not, she's fighting the cancer and fighting her emotions at the same time keeping a brave face just for us, but she's not okay, and it is completely okay for her to not be okay. We argue and fight like most families do like most mother-son relationships do, but she's always there always my best friend.

Being the second time being diagnosed with this disease surgery is the only option to keep her alive, to keep her as my mother for more than the one year she's been told she's got left. We need to raise enough money before the first appointment on the 3rd of August for the treatment to go ahead! The initial surgery will remove all cancer tissue from her chest and spine follwed by a full mastectomy and then to check any surrounding tissue to see if it has spread any further than it already has. 
Please, please, please help her!! I cant lose my mum!! 

Thank you. X
