How many cases and deaths of breast cancer were estimated to be in 2003?

In 2003, were estimated to be 211300 new cases of invasive breast cancer diagnosis in women and 55700 cases of “in situ” breast cancer. Also, a number of 39700 women were accepted to die from this awful disease. In men, the expectations were about 1300 cases and 400 deaths, which represent only 1% of all breast cancers.



You can find below more detailed information about estimates of breast cancer diagnosis from 2003, in the United States:



-         Under the age of 30 were estimated 100 cases of in situ breast cancer which represents a percent of 0.2, 1000 cases of invasive cancer (0.5%) and 100  deaths (0,3%).
-         Between the ages of 30 and 39 years were estimated 2100 cases of in situ breast cancer (3,8%), 10500 cases of invasive cancer (5.0%), and 1300 deaths (3.3%).
-         Between the ages of 40 and 49 years were estimated 12600 cases of in situ breast cancer (22.6%), 35500 cases of invasive cancer (16.8%) and 4300 deaths (10.8%)
-         Between the ages of 50 and 59 years were estimated  15700 cases of in situ breast cancer (28.2%), 48700 cases of invasive cancer (23%) and 7000 deaths (17,6%)
-         Between the ages of 60 and 69 years were estimated 11500 cases of in situ breast cancer (20.6%), 43100 cases of invasive breast cancer (20.4%) and 7400 deaths (18.4%)
-         Between the ages of 70 and 79 years were estimated 10100 cases of in situ breast cancer (18.1%), 45600 cases of invasive breast cancer (21.6%) and 9500 deaths (23.9%)
-         In women over 80 years were estimated 3500 cases of in situ breast cancer (6.3%), 27000 cases of invasive breast cancer (12.8%) and 11000 deaths (25.4%)

Total = 55700 cases of insitu breast cancer, 211300 cases of invasive breast cancer and 39700 deaths.

But how has the occurrence of breast cancer changed over time we will find out from the next lines.
Incidence rates of invasive breast cancer in women for all races combined, since 1973 show three distinct phases
–        the incidence was essentially constant between 1973 and 1980
–        between 1980 and 1987 the incidence rates increased by almost 4% per year
–        and also, the incidence rates increased again between 1987 and with 0,4% per year.



Also, the age probabilities of developing breast cancer are:
-         If current age is 20 then the probability of developing breast cancer in the next 10 years is 0,05% or 1 in 2152.
-         If current age is 30 then the probability of developing breast cancer in the next 10 years is 0,40% or 1 in 251.
-         If current age is 40 then the probability of developing breast cancer in the next 10 years is 1,45% or 1 in 69.
-         If current age is 50 then the probability of developing breast cancer in the next 10 years is 2,78% or 1 in 36.
-         If current age is 60 then the probability of developing breast cancer in the next 10 years is 3,81% or 1 in 26.
-         If current age is 70 then the probability of developing breast cancer in the next 10 years is 4,31% or 1 in 23..
