Prostate Cancer Statistics
American Cancer Society (ACS) projected prostate cancer as the second most prevalent cancer among American men. 217,730 new cases and approximately 32,050 mortality were predicted for the year 2010 in USA alone by ACS.
What this essentially means is that 1 in every 6 males are at risk of being diagnosed with prostate cancer in their lifetime, whereas 1 in every 36 diagnosed will succumb to the disease.
Interestingly though, there are approximately 2 million prostate cancer survivors in the United States of America. A methodical and closer look at the different important prostate cancer statistics will further reiterate the prolific health care burden that prostate cancer has assumed. Unless otherwise mentioned, most of the statistics described in this article are from the Surveillance Epidemiology and End Results (SEER) (a sister organization of the National Cancer Institute, NCI) annual publications.
Incidence and Mortality
There is hardly any patient diagnosed before age 35; but 30.7% and 35.3%, respectively, are diagnosed between the ages of 55 and 64 and 65 and 74. Based on positive case diagnosis during the period of 2004-2008, the age-adjusted incidence rate was 156.0 per 100,000 men. A race specific incidence rate is shown in the above table. The median age of mortality due to prostate cancer was 80 years in the period of 2003-2007. In fact, more than 80% of all prostate cancer deaths happened in men above 70 years of age; 40.3% being the maximal death rate seen in the age group of 75-84 years. The overall age-adjusted death rate was 24.7 per 100,000 men per year during the same period (adjacent table).

Survival and Stage
Relative survival rates express the comparative survival of cancer patients in respect to the general population, which in turn gives a qualitative and quantitative measure of the effect of the cancer. Using relative survival rate statistics, the overall 5 year survival between 2001 and 2007 was 99.44, 96.2% for black men and significantly higher in white men (99.7%). Hispanic and Asian men are at the lowest risk of developing prostate cancer. The stage distribution represented in the adjacent table is based on the Summary Stage published in 2000.
Prevalence, Diagnosis and Prognosis
As of January 1, 2008 there were 2,355,464 prostate cancer survivors in USA. But a look back will show that as many as 17 of every 100,000 me in USA died of prostate cancer in 1932. The number increased 192% to 25 in 100,000 in 1991. Although the number of incidence has decreased over the years (6 in every 100,000 men), the more important fact is that the number of overall deaths due to prostate cancer is on a steady decline.
An interesting statistic is the stage at which the disease is diagnosed. 91% of cases are identified when the tumor is localized to the prostate gland or has just spread to regional lymph nodes, whereas 5% of cases are diagnosed after metastatic progression. This essentially shows that current prostate cancer diagnostic tools are advanced and well equipped.
