Horvath G, Andersson H, Paulsson G. Characteristic odour in the blood reveals ovarian carcinoma. BMC Cancer. 2010 Nov 24;10:643. PubMed PMID: 21106067; PubMed Central PMCID: PMC3004816. [Free full text via PubMed Central.]

Researchers at Sahlgrenska University Hospital, Göteborg, Sweden, followed on to their earlier work to determine whether trained dogs can detect a specific odor emitted by ovarian carcinomas and borderline ovarian tumors in blood from patients with those diseases.

When two trained dogs tested ovarian cancer tissues and blood from patients with ovarian carcinoma, the results in cancer tissues showed a sensitivity of 100% and specificity of 95%, while the blood tests showed sensitivity of 100% and specificity of 98%.
