The rates of breast cancer vary widely in different parts of the country and the world, and can vary among patients of different ages and races as well. There is also a huge difference in breast cancer rates between genders, with women being one hundred times more likely to get breast cancer than men. As for 2011, estimates of more than 225,000 new cases of invasive breast cancer will be diagnosed. There will be more than 57,000 cases of in situ breast cancer, which is both ductal carcinoma in situ breast cancer and lobular carcinoma in situ. Out of those cancer cases, there will be almost 40,000 deaths this year from the disease.
As stated, breast cancer is much more rare in men than it is in women. However, the statistics for men are still up there, with more than 2000 cases of breast cancer diagnosed in men, with 450 of them resulting in death. The rates of breast cancer among men are much lower than with women, including cases of primary breast cancer, and a new cancer found in men that have already had it. Neither of the statistics that are listed here include an emergence of the same breast cancer that was already present. The mortality rate in men is lower as well.
Breast Cancer Rates by State
According to statistics taken from the years 2003 to 2007 from women, breast cancer varies a little bit by state, but with no real stand outs. The USA state with the highest rate of breast cancer in women from these years was the District of Columbia, with 139 cases per 100,000 women. These cases were all invasive breast cancer. The state that has the lowest number of invasive breast cancer cases per one hundred women is Arizona, with only 104 cases. There has not been any definitive links shown to certain geographic areas or states to the cases of breast cancer.
Age as a Risk Factor for Breast Cancer
Age is one of the main risks for breast cancer. In fact, the two primary risk factors are being female and age. Women have more of a risk for this type of cancer the older that they are, with most cases occurring after age fifty. This is why it is so important to get checked early and have it detected as quickly as possible. Five percent of breast cancer cases happen in women that are under the age of forty, with the other ninety five percent in women older than that. It should also be noted that while the risk of breast cancer is low in younger women, there are certain genetic factors that increase the risk. Another statistic is regarding pregnant women. For every 100,000 pregnancies, there are thirteen cases of breast cancer, and it may be harder to detect breast cancer when the breasts are swollen or lactating.
The Leading Cause of Death Among Women Worldwide
According to data from the World Health Organization (WHO), breast cancer is the leading cause of death in women worldwide. Each year, there are more than half a million people that die from this disease. More groups exist to fund research and educate people about breast cancer than any other type, including the Susan G. Komen for the Cure Foundation.
