Detecting cancer early with just one blood test.
The NHS is set to pilot a new blood test to improve its ability to detect cancer early. The Galleri blood test, developed by Californian healthcare company Grail, will be piloted with 165,000 patients starting in mid-2021.
Traditionally patients are referred to cancer services if they begin exhibiting concerning symptoms for cancer (such as weight loss, lethargy, blood in stools, urine or coughing), or if they qualify for the various screening programmes set up in the UK. Unfortunately, some cancers present with symptoms late, when cancer may already be too advanced, and screening programmes are only available for certain cancers that are prevalent, easy to test and easy to detect early. Currently, only half of all cancers in the UK are diagnosed at stage one or two, and the NHS aims to increase this number to 75% by 2028. The earlier cancer is found, the higher the likelihood of survival.
