Cervical cancer is
the second most common cancer in women worldwide. In the United States, according to the American Cancer
Society, about 12,710 women were diagnosed with cervical cancer in 2011 and
4,290 women died of the disease. Cervical cancer is caused by “high-risk” types
of the human papillomavirus (HPV). HPV is a very common sexually transmitted
infection, about 3 of every 4 adults will have had HPV at some time in their
lives, and most HPV infections go away without treatment. Infections that do
not go away can cause cells on the cervix to change and become abnormal. Over
time, abnormal cells can develop into cervical cancer.

Cervical cancer is a disease
Cervical cancer affects the cells of the cervix, which is
continuous with the lower part of the uterus that connects to the vagina.
Infection with various strains of HPV, a sexually transmitted agent, induce
over 98% of cervical cancer cases.

Cervical cancer does not cause any symptoms until it has
advanced to a very late stage. That’s why it’s important to get screened
regularly even if you feel healthy. There are 2 tests used for cervical cancer
screening, the Pap test and the HPV test. The Pap test looks for abnormal cells
that can develop into cervical cancer. If necessary, the abnormal cells can be
treated, but keep in mind that abnormal cells are not yet cancer. Treated
effectively at an early stage, abnormal cells will not develop into cervical
cancer. Current U.S. screening guidelines recommend women have their first Pap
test at age 21.

But as the cancer progresses, the following symptoms may
appear:
- Abnormal vaginal bleeding
- Bleeding between regular menstrual periods
- Bleeding after sexual intercourse, douching, or a pelvic examination
- Menstrual periods that last longer and are heavier than normal
- Bleeding after onset of menopause
- Increased vaginal discharges
- Chronic pelvic pain
- Pain during sex
- Pain during urination

Women should be aware that routine infections or other
health-related conditions can also cause identical symptoms. Only a
gynecologist can perform the appropriate evaluations and tests to determine
whether cervical cancer can be suspected.
In most women with HPV infection, a woman’s immune system
is strong enough to keep the virus in check so that it does not grow and take
over healthy cervical cells.

However, in a minority of women, the virus is able to
survive, grow and cause a population of cells on the surface of the cervix to
become cancerous.

Please
take the time to schedule your annual Pap test, and encourage your friends and
family to do the same!
