Statistics on Cervical Cancer
Cervical cancers originate in the female reproductive organs. The cervix, or uterine cervix as it is sometimes called, is located in the lower part of the uterus below where a fetus grows. The cervix connects the womb to the birth canal. There are two parts of the cervix: the endocervix and ectocervix. The endocervix is closest to the womb, while ectocervix is closest to the vagina. The endovercix and ectocervix meet in the middle at the "transformation zone," which is where most cervical cancers originate.

How Many People Get Cervical Cancer?

According to the American Cancer Society, doctors will diagnose approximately 11,270 new cases of invasive cervical cancer in the Untied States in 2009. According to the National Cancer Institute, as of 2006, there were an estimated 248,166 living women who either had cervical cancer or who had a history of cervical cancer.
What Age Are People Diagnosed?
-
According to the National Cancer Institute, between 2002 and 2006, 48 was the median age at which women were diagnosed with cervical cancer. During this time, .2 percent of patients diagnosed with cervical cancer were 20 years of age or younger. 14.9 percent of cervical cancer diagnoses were in women aged 20 to 34. Women between 35 and 44 accounted for 26.2 percent of new diagnoses. 23.5 percent of new cases were found in women between the ages of 45-54. Women between 55 and 64 made up 15.8 percent of new diagnoses. 10.4 percent of diagnosed patients were between 65 and 74. 6.6 percent of diagnosed patients were between 75 and 84. Finally, the last 2.5 percent of diagnosed patients were 85 years of age or older.

Who Is Most Likely to Get Cervical Cancer?
-
Race has an impact on the likelihood of developing cervical cancer. The American Cancer Society statistics suggest that the cancer is most prevalent in Hispanic women. African Americans also have a higher rate of cervical cancer then Caucasians.
According to the National Cancer Institute, an average of 8.2 out of every 100,000 women will develop cervical cancer. For white women, that average drops to 8.1 out of every 100,000. For black women, the number is 10.4 out of every 100,000, and for Hispanics the number is 12.7 out of every 100,000. The numbers are the lowest for Asians and American Indians, who have rates of 7.6 and 7.2 per every 100,000 women respectively.
What Are The 5-year Survival Rates by Stage?
-
Survival data is collected in terms of five-year survival rates. Five years is the minimum rate of survival; many women who are said to be alive five years after diagnosis live much longer than five years after diagnosis. Survival rates are broken down by stage, which is a measure of how advanced the cancer is. Stage IA cervical cancer, the least invasive cervical cancer, has a five-year survival rate about 95 percent. Stage IB1 has a five-year survival rate at 90 percent. Stage IB2 has a five-year survival rate of between 80 and 85 percent. When the cancer advances to Stage II A or Stage II B, the survival rate drops to between 75 and 78 percent. Stage III has a much lower survival rate, at between 47-50 percent. Finally, the five-year survival rate for women diagnosed with Stage IV cervical cancer is between 20 and 30 percent.
How Many People Die From Cervical Cancer
-
According to the National Cancer Institute, approximately 2.5 out of every 100,000 women in the U.S. die of cervical cancer every year. These numbers were based on figures from 2002-2006, and adjusted for age. The American Cancer Society estimates that, in 2009, approximately 4,070 women will die from cervical cancer. This is a 74 percent lower rate of death than between the years 1955 and 1992. The ACS estimates that the death rate will continue to decline due to advances in medical technology and early screening procedures, including pap smears.
According to the National Cancer institute, the median age of cervical-cancer related death is 57 years old.
