A new study has revealed that breast cancer could be sexually transmitted.
December 14, 2006 (Press Release) --
A new study has revealed that breast cancer could be sexually transmitted.
Emeritus Professor James Lawson of the University of New South Wales and colleagues have found the same form of the human papillomavirus (HPV) associated with cervical cancer in almost half the breast tumor samples they tested.
It`s the first study of its kind in Australia, although international studies have also found cervical cancer-related HPV in breast cancer cells. He says while the evidence is far from conclusive, "it`s possible and totally worthy of investigation" to suspect that HPV could also cause breast cancer.
Lawson says it`s possible that HPV is spread by sexual activity or during showers or baths, when the virus could be transferred from the genital area to the breasts via the nipple ducts.
"We know that the virus explodes out of the cell and is spread by touch, so it`s fairly obvious that it could be spread by sexual activity to the breast, you could also argue that it would be spread by washing and bathing," he was quoted by ABC, online, as saying.
Lawson says more research is needed to establish whether HPV is actually causing the breast cancer or if women with breast cancer are more prone to infection with the virus.
Lawson and colleagues last year published the results of a DNA analysis which found 24 out of 50 breast cancer samples also tested positive to HPV 18, the same form of the virus implicated in breast cancer.
A subsequent review, published in the journal Future Microbiology in June this year, found various forms of high-risk HPV had been identified in 10 separate breast cancer studies since 1999.
In a letter published online in the British Journal of Cancer last month Lawson reports that a review of the 2005 study found women with HPV positive breast cancers were on average about eight years younger than those whose tumors did not test positive to the virus.
