A brave teenage cancer patient has received a wonder drug to shrink an “incurable” brain tumour.Kira Noble, 16, was diagnosed with neuroblastoma when she was 11.Since then, she had six relapses of the disease, increasing the difficulty of treatment, and undergone 20 rounds of chemotherapy and various other gruelling treatments.Early last year, Kira was dealt another cruel blow when doctors revealed that her illness was “incurable but treatable”.However, after the teenager started taking experimental drug Lorlatinib - said to be a “much kinder” treatment than chemotherapy - last April, she has made massive improvements.Now, there is just one nodule of the cancer remaining - measuring millimetres, instead of centimetres, in size.
