Mouthwash test for breast cancer

A new mouthwash test can predict a woman's risk of breast cancer years before the disease sets in. It works by collecting DNA samples from the lining of the cheeks and studying them for genetic activity linked with the development of cancer. By matching the results up with a database of 8,000 women with and without cancer, scientists can predict at what stage in life a woman's cancer risk is greatest.

Called Oncovue, the test costs £595 and is being launched in the UK this week. Patients will a few teaspoonfuls of mouthwash around their mouths for 30 seconds, then spit it into a container. This gives enough cells from the cheeks to do the test. Samples are sent to a laboratory in Oklahoma, the firm which developed the test.

And this will tell how likely a woman in her 20s or 30s is to develop the disease, and at what stage in her life. It will tell you how low or high risk you are and if you are high risk which age group you will develop it in i.e. below 44, 45 to 54, and over 55. Those pinpointed as high risk could opt to have annual mammograms from a young age, rather than wait for three-yearly NHS screening to begin at 50. Or if it shows a woman's risk is highest in her 50s, she might want annual private checks rather than three-yearly on the NHS. Private mammograms cost around £300.

The test will initially be available at private hospitals such as the London Clinic and Nuffield hospitals in Tunbridge Wells and Cheltenham.

Dr. Chris said: "Scientists are making great progress in unravelling the genetic faults that influence breast cancer risk, but this type of DNA testing can't yet supply all the answers. There is a danger that this type of test could cause unnecessary anxiety for some women. Or alternatively, it could give others a false sense of security: "low risk" does not mean "no risk". Still continue to be breast aware, report any changes to your doctor promptly, and attend screening appointments when invited, as early detection is important for successful treatment."
