2012 Breast Cancer Report
Following is a breast cancer site analysis by Koteshwar Telukuntla, MD and Mary Koshy, MD. The report includes statistical comparisons for patients diagnosed at MMH. Unless stated otherwise, the statistical graphs and tables found in this study include only analytic cases.
Breast cancer is a cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.
When breast cancer cells spread, the cancer cells are often found in lymph nodes near the breast. Also, breast cancer can spread to almost any other part of the body. The most common are the bones, liver, lungs, and brain. Breast cancer is the most common cancer among American women, except for skin cancers. About 1 in 8 (12%) women in the US will develop invasive breast cancer during their lifetime. 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 36 (about 3%). Death rates from breast cancer have been declining since about 1989, with larger decreases in women younger than 50. These decreases are believed to be the result of earlier detection through screening and increased awareness, as well as improved treatment. The American Cancer Society estimates in the United States in 2011, that there will be 230,480 new cases of invasive breast cancer diagnosed in women. The estimate for newly diagnosed breast cancer cases in Florida is 15,300. At Manatee Memorial Hospital there were 104 female newly diagnosed and treated breast cancer patients in 2011.
Research has shown that women with certain risk factors are more likely than others to develop breast cancer. Studies have found the following risk factors for breast cancer:
Age, personal history of breast cancer, family history, certain breast changes: (atypical hyperplasia and lobular carcinoma in situ [LCIS]) gene changes (BRCA1, BRCA2), and reproductive and menstrual history have all been shown to increase the risk of breast cancer. Additional risk factors include race, prior radiation therapy to the chest, increased breast density, being overweight or obese after menopause, lack of physical activity and drinking alcohol. Many risk factors can be avoided. Others, such as family history, cannot be avoided. Women can help protect themselves by staying away from known risk factors whenever possible.
The following chart reflects the age at diagnosis of 2006 and 2011 breast cancer cases diagnosed and treated at Manatee Memorial Hospital:
Florida County by County Comparison for Breast Cancer—2006
Below is information provided by the Florida Cancer Data System and Office of Vital Statistics, that illustrates age-adjusted incidence and mortality rates of breast cancer by county in the state of Florida for 2006. Manatee County incidence rate is significantly lower than the state rate.
Screening and Diagnosis
The benefits of screening for breast cancer is an area of active research and the American Cancer Society continues to strongly recommend mammography as a screening tool in the early detection of breast cancer. Yearly mammograms are recommended starting at age 40 and continuing for as long as a woman is in good health. Clinical breast exam (CBE) about every 3 years for women in their 20s and 30s is recommended and every year for women 40 and over. Women should know how their breasts normally look and feel and report any breast change promptly to their health care provider. Breast self-exam (BSE) is an option for women starting in their 20s. Some women – because of their family history, a genetic tendency, or certain other factors – should be screened with MRI in addition to mammograms. Women at high risk (greater than 20% lifetime risk) should get an MRI and a mammogram every year. Women at moderately increased risk (15% to 20% lifetime risk) should talk with their doctors about the benefits and limitations of adding MRI screening to their yearly mammogram. Yearly MRI screening is not recommended for women whose lifetime risk of breast cancer is less than 15%.
