http://www.guardian.co.uk/society/2008/oct/06/health.cancerEnough is known about the causes of breast cancer to make a vaccine or prophylactic drug a real possibility, a leading cancer expert said last night.
Professor Valerie Beral of Oxford University, who leads the Million Women's Study into the causes of the disease, told the Guardian the study had put beyond doubt what had long been guessed - that many breast cancers are caused by the absence of hormonal changes connected with childbirth.
Beral challenged the scientific community to turn its efforts to preventing breast cancer. While money and effort is poured into better drug treatments, hardly anyone is working on prevention.
Speaking to the Guardian, she said that while death rates have been slashed by new drugs and earlier diagnosis, the number of women getting breast cancer and having to go through traumatic surgery and chemotherapy was rising.
