Breast cancer statistics involves the death rate, survival rate as well as the number of the patients undergoing breast cancer. This statistics may vary as per the states or countries, since at some extent race is associated with the development of breast cancer. Breast cancer is considered as one of the leading fatal disease mostly seen in the women.

Facts allied with breast cancer statistics:

After skin cancer, breast cancer is the most common disease among the women in America. As per the studies of American Cancer Society, about 12 percent of women (around 1 in 8 women) develops invasive breast cancer in their course of lifetime.

Current estimates of breast cancer calculated the by the American Cancer Society are as follows:

  • As per the estimation, around 230,480 women are diagnosed with invasive breast cancer. This number refers to the new cases.
  • The number of women died due to breast cancer is around 39,520.
  • About 57,650 new cases of CIS (carcinoma in situ) are diagnosed. CIS refers to the non-invasive and early stage of breast cancer.
  • In 2010, about 207,090 women were diagnosed to undergo invasive breast cancer in U.S while around 54,100 were found to undergo non-invasive breast cancer.

Risk of breast cancer and breast cancer statistics:

  • The risk of breast cancer in women doubles approximately if she has a relative (sister, mother, and daughter) at first degree, which has been examined with breast cancer. Around 20 to 30 percent of women undergoing breast cancer are due to a family history of breast cancer.
  • Age can be considered as the major factor for the development of breast cancer.
  • Around 10 to 15 percent of breast cancer cases are due to the mutations in the genes that are inherited from the patient's father or mother. Mutation in the genes BRCA1 and BRCA2 is the most common cause of breast cancer.
  • Women with these abnormal changes in the genes are at around 80 percent risk of developing breast cancer throughout their lifetime, but most likely it is diagnosed before the age of 40 or prior to menopause.
  • About 70 to 80 percent of women who do not have any family history are undergoing breast cancer, due to the genetic mutations that takes place as a result of the age process instead of the inheritance of mutations.
  • In many cases, breast cancer occurs due to the heredity.

Is there any fall in the breast cancer statistics:

As per the studies, it is found that the since last two decades, the incidence of breast cancer in women is lowered by about 2 percent. This stat is found from year 1998 to 2007. This fall in the development of breast cancer was seen in women aged more than 45 years. This decrease was due to the least use of hormone therapy in women of this age group. This fact linked with the study of hormone therapy to an elevated rate of breast cancer as well as heart disease.

After lung cancer, breast cancer is the most threatening form of cancer that reduces the possibility of survival of patient. The possibility of death in women due to breast cancer is about 1 among 35 i.e. about 3 percent. As per studies, the survival rate of breast cancer in women is declining since 1990. This decrease is more in women younger than 50 years. This rate of decrease are considered to be result of increased awareness of breast cancer, early diagnosis through screening as well as the used of advanced technologies.

Currently, more than 2.5 million patients are found to be survived from breast cancer in the United States. This ratio involves the number of women who are treated and are still being treated.

Breast cancer statistics of particular state or country helps to study the variation of the stats in different countries. These stats are lowering down these days due to the advancement in the technologies.
