Its not often you see a stream of supercars in convoy, but thats exactly what happened at North Devon District Hospital (NDDH) on Monday. The impressive collection of cars stopped by to raise awareness of bowel cancer by charity Bowel Cancer West. The cars which included a Mclaren 675 LT, both a 1995 and 2008 Aston Martin V8 Vantage, a Porsche Carrera S and Porsche Cayman all took part in the Bowel Cancer West Grand Tour, which ran from Lands End to Bristol. During their visit to NDDH the drivers put on an impressive display for onlookers and spoke to bowel cancer patients and staff about what they are trying to achieve through the tour such as local screening services and symptoms. The tour was led by bowel cancer survivor Roger Stone and colorectal surgeon Mark Coleman, who operated on Mr Stone. Mr Coleman, consultant surgeon at Plymouth Hospitals NHS Trust, said: Its great fun driving these incredible cars, but there is a very serious message we are trying to get out that bowel cancer can be cured in over 90 per cent of cases if caught early. During our tour we are passing on life-saving advice, including that anyone who receives a free invitation to an NHS screening test in the post should take up this opportunity. Mr Stone said: Im so grateful to Mark for saving my life and delighted I can do this tour with him. If I had ignored my symptoms another few weeks, I probably wouldnt be here today. The work this charity does to raise awareness is so important. Northern Devon Healthcare NHS Trust launched a bowel scope screening service in February as part of a wider bowel cancer screening programme. Invitations to come up to the endoscopy unit at NDDH for bowel scope screening are sent out to men and women once they have reached their 55th birthday. The service is being rolled out gradually, with the number of invites going out expected to increase over the next year. Tanja Brackenbury, specialist nurse practitioner, said: The key benefit of bowel scope screening is prevention of colorectal cancer. Bowel cancer is a very treatable condition when caught early, so we really encourage people to attend their bowel screening appointment, when invited. We are really grateful to Bowel Cancer West for stopping by and for raising awareness in such a fun and attention-grabbing way.
