This graph illustrates that chances of developing Cancer directly correlates with age in most instances. There is a slight increase of cancer cases from year 1999 until 2005 in the age range of 45-54. However, the most significant increase from Cancer cases in this time period is age bracket 55-64.
From the Google Chart Data sets I was able to also look at Cancer cases per type or site. The most prominent cases are Lung and Bronchus with a significant increase of 9.5% from year 1999 to 2005. Despite the spike of Prostate cancer cases in the early 2000s, cases have remained consistent in this time period. Colon Cancer remains a steady threat. Based on the data of both charts, the leaders in Cancer are Lung/Bronchus, Prostate, Breast and Colon. According to the American Cancer Society (cancer.org), the following is recommended:
Cervical Cancer - No later than 21
Mammograms - Age 40
Prostate Cancer - Age 45
Colorectal Cancer/Polyps and other tests that primarily find Cancer - Age 50
