Brooke Pemberton, 32, from Watchfield near Swindon, lives with Stage 4 endometriosis and needs surgery to remove the endometriosis and detach her organs which have stuck together. Brooke has been she could face up to an eight-year wait to get the surgery she needs at the John Radcliffe Hospital in Oxford, as the Great Western Hospital is unable to provide endometriosis surgery. "We have seen a private doctor and have been quoted £10,000 for surgery which is something I cannot afford. "I have three young children, my husband works hard, but that is not something we cannot entertain. Thomas, Evelyn, Harry and Daniel will take on the The Tough Mudder challenge on Saturday, August 15, and the family has already raised close to £1,000 on their GoFundMe page.
