STATISTICS ON CANCER IN THE UNITED STATES

The last 25 years of investment in cancer research has resulted in significant advances in cancer prevention and treatment, and encouraging declines in cancer mortality rates. Yet cancer remains the second leading cause of death in the United States, behind heart disease.

INCIDENCE

It is estimated that nearly 1.4 million new cancer cases will be diagnosed this year and approximately 560,000 people will die from the disease.

LEADING CANCER TYPES NUMBER OF NEW CASES PERCENTAGE OF NEW CASES Prostate 334,500 24.2 Breast 181,600 13.1 Lung 178,100 12.9 Colon & Rectum 131,200 9.5 Non-Hodgkinís Lymphoma 53,600 3.9 Other 503,400 36.4

SURVIVAL

Today, 4 in 10 people with cancer will live at least five years after diagnosis, up from the 1 in 3 survival rate in the 1960s. This translates into approximately 91,000 more survivors each year.

MORTALITY

U.S. cancer mortality rates have dropped annually from a 1990 high of approximately 135 deaths per year per 100,000 people to 130.8 per 100,000 in 1995.

CANCER GENETICS

The identification of specific genes linked to various types of cancer has led to promising new areas of cancer research. Below is a list of the susceptibility genes that have been identified to date, the type of cancer associated with their mutation, and the year they were identified.
