For 2011, The American Cancer Society estimates that in the United States:
- About 230,480 new cases of invasive breast cancer will be diagnosed in women
- About 57,650 new cases of carcinoma in situ (CIS) will be diagnosed (CIS is non-invasive and
is the earliest form of breast cancer).
- About 39,520 women will die from breast cancer
- Breast cancer is the second leading cause of cancer death in women, exceeded only by
lung cancer. The chance that breast cancer will be responsible for a woman's death is about
1 in 35 (about 3%).
- Most women have less than a 1 in 8 chance (about 12%) of developing invasive breast cancer
at some time in their lives.
Symptoms
In most cases, early breast cancer does not cause pain. Regardless, a woman should seek medical attention regarding any breast pain or other symptom that is persistent.
Common breast cancer symptoms:
- A change in how the breast or nipple feels - One may experience nipple tenderness or notice a lump or thickening in or near the breast or in the underarm area.
- A change in the appearance of the breast or nipple - Indicates a change in the size
or shape of the breast or nipple that is turned slightly inward. In addition, the skin or the breast, areola or nipple may appear scaly, red, or swollen or may have ridges
or pitting that resembles that of an
orange skin.
- Nipple discharge
Risk Factors
The exact causes of breast cancer are unknown but research has indicated that women with certain risk factors are more likely than others to develop the disease. Some risk factors can include older age, high fat diet, personal or family history of breast cancer, obesity, taking hormones such as estrogen and progesterone.
Recommendations for Screening
Early detection and treatment offers the best chance of survival. When breast cancer is diagnosed at an early stage and is confined to the breast, the 5-year survival rate is 98%.
- Annual screening mammograms starting at age 40. If there is a family history of breast cancer or any specific risk concerns, please consult with your healthcare provider to determine when to begin your mammograms.
- Clinical breast exams every three years beginning at age 20 and annually after
40 by a healthcare provider.
- Monthly breast self-exams starting by
age 20.
