Analysing loyalty card data could help doctors spot ovarian cancer cases earlier

By looking at loyalty card data on over-the-counter medication, doctors could spot ovarian cancer cases sooner, according to new research. Data has shown the purchase of pain and indigestion medication was higher in women who later were diagnosed with ovarian cancer.

Researchers at the Imperial College London looked at 300 women, and noted those who purchased the medication had a higher risk of being diagnosed about eight months later. The research is thought to be the first of its kind for cancer.
