Breast cancer is the most prevalent malignancy in women in the world. Although major advances have been made in early detection and treatment, there are approximately the same numbers of women dying from breast cancer today as there were over 100 years ago. Therefore, treatment strategies designed to prevent the risk of breast cancer will have a significant impact in saving lives.
For so many women, there is no more dreaded disease than breast cancer. The mere words breast cancer elicits fears related to loss of body image and sexuality, surgery, and even death. As is the case for most cancers, the exact cause of breast cancer is not clearly known. However, compared to other cancers, breast cancer is on the more treatable end of the spectrum if diagnosed early.
It is considered a "favourable" cancer because it can be detected early by breast examination, mammography or other means and is often relatively slow to develop when compared with other cancers.
In addition, our knowledge of how breast cancer develops is expanding rapidly. As a result, new medications are being developed to reduce the risk of breast cancer. In addition, it is widely held that for the majority of women, lifestyle changes, a healthy diet, exercise and weight reduction are able to reduce the chance of developing breast cancer. Even given these advancements, to date, the most important strategies in improving survival are still breast cancer screening and early detection coupled with the control of pre-malignant or early stage, breast cancers by chemoprevention techniques.
