Angelina's surgery to eat and drink

Hi my mum Angelina last year was diagnosed with adenoid cystic carcinoma on the back of the larynx very rare form of cancer. In october last year she had total larengectomy with a free flap reconstruction.A part of her oesophagus was removed and replaced with a section of intestine.In February-March this year she had radiotherapy due to this the result was severe narrowing of the oesophagus.She has a peg tube for feeding and her quality of life is poor and she's losing weight gradually. Im her son and doing this campaign  hoping to raise enough funds so she can do the surgery in USA and cover the hospital bills the doctors cant do surgery in Australia she can only do surgery in USA .Please help us so she can at least eat and drink like every normal person would.
