Does the 'Kissing disease' virus cause breast cancer?

Epstein-Barr virus

Epstein-Barr virus, the cause of infectious mononucleosis, or 'mono' - the 'kissing disease', is also a known cause of head/neck cancers, blood cancer and stomach cancer and others. New research has now shown that the virus can cause breast cells to become cancerous as well. Whether the virus causes breast cancer in humans is not yet known.

Because about 90% of people in the world have been infected with this virus at some time, the results make the development of a vaccine even more important.
