Sahgrenska Academy Researchers at the University of Gävle and KTH Royal Institute of Technology, Sweden, were able to prove in tests that the ovarian tissue with ovarian cancer, the healthy exudes a different aroma.

In a previous project, the researcher György Horvath used dogs to demonstrate that trills ovarian cancer issues a specific smell. The dogs were able to use this scent to distinguish between healthy tissue and the ovarian cancer tissue, and other types of gynecologic cancer.

The discovery that the blood of patients with ovarian cancer also has the same specific flavor was published in the journal BMC Cancer.

In partnership with Professor Thomas Lindblad, from KTH, and the researcher José Chilo of Gävle, Horvath worked to detect this aroma different from using an electronic nose developed by KTH.

We were able to detect and record the smell of a form of ovarian cancer, but the smell of a fallopian tube and uterus of a healthy, Horvath said. This technique confirmed the smell of a cancer will have practical implications for a specific method, sensitive enough, you can save hundreds of lives per year in Sweden.

An electronic detector of smell is more sensitive than the existing electronic nose, is already being tested. The basic structure is the same as the electronic nose, but this new mechanism was added to components to increase sensitivity.

Our goal is to be able to analyze blood samples from apparently healthy and detect ovarian cancer early, when still pose be cured, Horvath concluded.
