Collect picture of Michelle Cartwright (32) at The Royal Orthopaedic Hospital, Northfield, Birmingham, West Midlands taken just after surgery on the tumour April 13, 2015. A mum-of-three has told how doctors realised she was suffering from a rare form of cancer when they spotted a tumour in scans she had after a CAR CRASH. See NTI story NTICANCER. Michelle Cartwright, 32, suffered minor leg injuries when an off-duty police officer smashed into her new Nissan Duke in June last year. But she went back to her GP six weeks later in August when the her right limb remained swollen. Michelle - who was pregnant at the time - underwent an MRI scan and doctors were stunned when they discovered a tumour in her leg. She then underwent painful bone tissue tests before medics gave her the devastating news she had Liposarcoma, a rare form of cancer, in October. Doctors told Michelle she needed to have her daughter as early as possible so she was induced and baby Lilly was born on December 4. Incredibly, the bouncing baby girl weighed 6lbs 14oz and was completely healthy despite being delivered five weeks and six days premature.
