'From the bottom of our hearts - thank you'

Available for over a year

The sister of a young Leicestershire man who's seeking treatment for an aggressive brain tumour has told us the family are overwhelmed and humbled by the amount of money raised to help him. 21 year old Isaac Wilton from Coalville was diagnosed with cancer after collapsing during a gym workout. His family launched a fundraising campaign to pay for immunotherapy treatment which isn't available on the NHS for the grade 4 glioblastoma. The initial target of £155,000 was raised within a week, with donations pouring in from across the world. Isaac's sister Harriet has been talking to BBC Leicester's Ady Dayman.
