Uncovering a gene for oesophagal cancer

...ar screening where the oesophagus is examined by a miniature camera and tissue biopsies taken to reveal any potentially cancerous change. Meanwhile, the search for the gene has been narrowed down to one small area of chromosome 17. Once it's identified, it will shed light upon not just inherited oesophagal can...

New pancreatic surgery

...ive surgery involves a tiny incision through which miniature instruments are inserted. The surgeon uses a computer screen as a guide through the operation. // It's an advance to use keyhole surgery on the pancreas.
