Breakthrough In Early Detection Of Ovarian Cancer

Cancer Screening

Blood Test: While no single blood test can confirm the existence of ovarian cancer in women, periodical blood tests can build a profile of the level of the CA-125 protein evident in the human body.

An article, by Adam Withnall, in The Independent reports that blood tests for a protein, CA-125, could be an early predictor for ovarian cancer. The key finding in this 14-year British research study is that changes in CA-125 levels correlates with increased incidences of ovarian cancer; the test has an accuracy rate of 86 per cent.

So, while no single blood test can yet predict ovarian cancer, periodic blood tests can compare levels, or changes, in the CA-125 protein. This is the building of a profile, which is now becoming more common in detecting all types of cancers.

Withnall writes:
And UCLA’s Professor Usha Menon said that the new test, involving tracking changing levels of the protein CA125 in the blood, could change the way doctors screen for ovarian cancer in the UK. “There is currently no national screening programme for ovarian cancer, as research to date has been unable to provide enough evidence that any one method would improve early detection of tumours,” Professor Menon said.
Tracking changes involves more work, more tests, more needle pokes, but thus far it represents the best hope of early detection of ovarian cancer, a disease that affects thousands of women each year; Ovarian Cancer Canada says: “There are 17,000 women living with ovarian cancer in Canada. It is estimated that this year in Canada, 2,600 women will be newly diagnosed with ovarian cancer. Ovarian cancer is the 5th most common cancer for women and is the most serious women’s cancer.” Globally, 239,000 women were diagnosed with ovarian cancer in 2012, says World Cancer Research Fund International, a cancer-advocacy group based in London, England.
