Terminal cancer patient Joanna Houghton from Chirk is challenging an NHS decision to refuse a drug that could improve her wellbeing and prolong her life, beacuse she lives just half a mile from the English border. See SWNS story SWMDcancer. A seriously ill mum-of-two has spoken of her devastation after being denied a life prolonging cancer drug - because she lives HALF A MILE over the Welsh border. Joannah Houghton, 47, was told she was not eligible for the palliative medication Avastin because there is no NHS funding for the drug in Wales. In a cruel twist of fate, the NHS worker of 22 years would have been entitled for it if she lived just five minutes down the road in England. Joannah, of Chirk, North Wales, has now spoken of her heartache now that her life could be cruelly cut short as a result of a cancer postcode lottery.
