Support my mum for cancer treatment

Hi dear, my name is Veronica. My mum was diagnosed of Metastatic Cauda Equino syndrome with the primary source from her colon just 1 week after arrival to Uk on a visit with my dad. Due to her visa restrictions, she is not entitled to public funds thus all her medical expenses will be paid for. Due to the urgency of her treatment and the sudden decline in her health, she had to be treated in the hospital as an emergency pending when she is stable enough to fly back home. We have already spent so much on their visa application /travel to the Uk and the estimated cost of £12,000 or more will be a lot of burden to carry keeping in mind that she still requires further treatment. This sudden life changing development have put my family in a very difficult position both mentally and financially. Will really appreciate any support I can get to ensure that my family survives this trying times.
