Breast cancer is the most common invasive cancer in women and the second leading cause of cancer death in women after lung cancer. Advances in screening and treatment for breast cancer have improved survival rates dramatically since 1989. According to the American Cancer Society (ACS), there are more than 3.1 million breast cancer survivors in the United States. The chance of any woman dying from breast cancer is around 1 in 38 (2.6%).
The ACS estimate that 268,600 women will receive a diagnosis of invasive breast cancer. Most breast lumps are not cancerous. However, women should visit a doctor for an examination if they notice a lump on the breast. A doctor stages cancer according to the size of the tumor and whether it has spread to lymph nodes or other parts of the body.
There is no way to prevent breast cancer. However, certain lifestyle decisions can significantly reduce the risk of breast cancer as well as other types.
These include:
- avoiding excessive alcohol consumption
- following a healthful diet containing plenty of fresh fruit and vegetables
- getting enough exercise
- maintaining a healthy body mass index (BMI)
Women should consider their options for breastfeeding and the use of HRT following menopause, as these can also increase the risk.
