Breast cancer facts

breast-cancer-211180
      Breast cancer is a major health problem in the United States of America and other countries around the world. Breast cancer ranks second among the most leading causes of cancer deaths among women in America. Until recently breast cancer occupied the top position among leading causes of cancer deaths in women, it still occupies an unenviable second position, second only to lung cancer. If skin cancer is excluded, breast cancer would be the commonest cancer among women living in America. As per the World Health Organization, higher than 1.2 million women get the new diagnosis of breast cancer every year across the world. These numbers represent huge health threats caused by breast cancer within the United States of America and across the world.

      Breast cancer is the leading cause of cancer deaths in the middle age group of women aged between 40 and 55 years. Breast cancer is uncommon among men; approximately 1450 new male breast cancer diagnoses are made every year in the United States. It is comforting to note that the mortality rates of breast cancer in women when considering all age groups together have declined in US by 2.8 percent for every year from 1990 to 2000. The declining death rates may very well be credited to the successful screening programs and progress in various treatment modalities of breast cancer.

      Risk of development of breast cancer can vary widely among different ethnic groups in the United States. Caucasian women in the United States have approximately 13.1% lifetime chance of developing breast cancer. African American women have slightly decreased chance of development of breast malignancy and the lifetime risk of breast malignancy among this subpopulation is approximately 9.6 (Source: SEER). Even though African American women have a relatively lesser incidence rate of breast cancer in comparison to Caucasian women, the death rate is approximately 28 percent higher in African American women in comparison to Caucasian women. There has been an increasing incidence of earlier forms (in situ and stage1) of breast cancer in America. The incidence of the earliest form of breast cancer (DCIS) has gone up by about 130% over the past few years. It is reasonable to assume that the increased incidence of earlier types of breast cancer is the direct effect of an excellent screening program resulting in earlier detection.
