A British woman has filed a lawsuit against the National Health Service (NHS) after undergoing six years of chemotherapy that was later found to be unnecessary. Samantha Smith, 45, was diagnosed with a brain tumor and told she needed surgery followed by long-term radiation and chemotherapy under the care of University Hospital Coventry. A new consultant later overseeing her case confirmed the shocking truth: Samantha should have only received chemotherapy for six months. Samantha stated, 'Undergoing chemotherapy is a grueling experience.' She added that she suffered severe health decline for nearly a decade, convincing herself the ordeal was necessary for recovery. She also mentioned she contacted Samantha's family, expressing deep regret for the overtreatment and its negative effects. The institution explained in its letter that the extended chemotherapy course Samantha received was not in line with national guidelines and was not supported by scientific evidence, confirming steps were taken to prevent such cases in the future. Although approved medical guidelines state that chemotherapy duration in such cases should not exceed six months, Samantha continued treatment for six and a half years. On the advice of oncology Professor Ian Brown, Samantha continued treatment for consecutive years, and was only asked to stop after his retirement. The doctor is now under investigation by the General Medical Council. Samantha, a mother of three, has hired lawyers to investigate the medical care she received, amid fears other patients may have been subjected to unnecessary treatment. She confirmed she still suffers from chronic fatigue, inflammation, and tooth decay, and is unable to return to work. Meanwhile, University Hospitals Coventry and Warwickshire announced it is conducting an internal investigation into the circumstances of the incident and the prolonged use of chemotherapy. It clarified the shock was immense upon learning that nearly six and a half years of her treatment was unnecessary.
