Cervical cancer ranks high on the list of common cancers that  plague women worldwide; it comes second after breast cancer in  prevalence.  More than 300,000 women die of cervical cancer every year,  worldwide, while in the United States alone, 13,000 cases of cervical  cancer are diagnosed every year, with about 4,000 deaths.  Most cases of  cervical cancer are reported in women between 40 and 55years of age,  though it is not unusual for women in their late thirties to be  infected.
However, unlike breast and other forms of cancer, the  cause and factors inducing cervical cancer is well established, except  in very limited number of cases.  The culprit in most cases of cervical  cancer is a sexually transmitted virus known as the Human Papilloma  Virus (HPV).  This virus can remain in the female genitalia for a very  long time, wreaking havoc on the cells of the cervix over a long period  of time.  It is reported that not all cases of HPV infections lead to  cervical cancer, however what is clear is that the virus is capable of  inducing abnormal changes in the cervical cells.  Some of these abnormal  changes in the cells result in what is medically known as 'high grade  lesions', which, sometimes may progress into cervical cancer.
Though  HPV is recognized as the reason behind most cases of cervical cancer,  there are other factors that play important roles in the cause and  progression of cervical cancer, these include; numerous sex partners  over a period of time; this increases the chance of HPV infection, the  presence of other sexually transmitted diseases, weak immune system,  which reduces the ability of the body to fight the virus, early sexual  activity, as non-matured cells of the cervix are more likely to succumb  to viral infection, and sometimes, cigarette smoking, though this has  not been conclusively established.  It is important to point out that  the body's immune system is usually capable of suppressing the viral  activity of HPV, thus cervical cancer only results in women whose immune  system could not sufficiently control the virus.
Pap smears are  the only established method for cervical cancer screening.  This test  involves brushing cells off the surface of the cervix and examining the  cells under a microscope for the presence of cancerous or precancerous  changes or lesions.  Presently, Pap smear is a routine test for women in  most developed countries and this has really helped to reduce the  number of deaths that are recorded due to cervical cancer.  However,  some critics have argued that the Pap smear test is not always  completely accurate.  It is advisable to carry out the test in at least  two laboratories, seek at least two professional opinions and then  compare, especially if you observe early symptoms of cervical cancer or  you believe you are perfectly alright but the test result shows  otherwise.
Though there are no clear cut symptoms of cervical  cancer, as it often progress without warning, the presence of the  following symptoms or signs might be an indication of the presence of  cervical cancer; vaginal bleeding after sexual intercourse or pain  during intercourse, unusual vaginal discharge, unusual bleeding between  menstrual periods or abnormally heavy bleeding during menstrual periods,  increased urine frequency or pelvic pain.  Again, these symptoms do not  necessarily mean that you have cervical cancer, but they are good  reasons for you to go see your doctor.
