Generally cancers are formed from oncogenic cells. These are the  cells that are affected by oncogenes; genes that stimulate  uncontrollable cell division leading to formation of tumors. When such a  tumor occurs in the cervix of a woman's body, it causes cervical cancer and the pap smear test is the test which is used to detect and confirm this.
The  cervix is the area near the uterus of the female anatomy. The  anatomical opening connecting to the cervix is the vagina. For the  examination of the area during the pap smear testing, the examiner will  insert an instrument called the speculum into the vagina.
Unlike other  similar devices, the speculum is used to enable direct vision. Once the  cervix is visible, the manual procedure of cleansing the cervix with a  cotton swab is carried out. A sample of cells are then collected and  studied under the microscope.
Pap smear  testing can be carried out on a regular basis to check for any kind of  abnormality. Getting tested in primary stages even before the  development of cancer can help treatment greatly. It is advised that  women should take their first pap smear test  at 21 years of age or soon after they start indulging sexual  intercourses. Women aged between 18 and 65 years are also encouraged to  regularly get tested
In a healthy body the cells will have  regular structure and functioning. But abnormalities may cause  irritation, inflammation and discomfort in the genital regions. In case  of benign swellings, treatment may include removal of the cervix. The  procedure is called Hysterectomy. However, this may not be needed for  all abnormal growths or lumps as in the case of subtotal hysterectomy,  where the uterus is removed but the cervix is left intact. In such case,  regular taking the Pap smear test becomes inevitable.
The  American Cancer Society advocates that the examination should be  carried out after 3 years of intercourse and regularly after every 2 to 3  years for women above the age of 30. Further, they recommend cessation  of the testing only after 70 years of age or incase of total  Hysterectomy as discussed above.
However, different organizations  promote different norms, but it is necessary for women of our country to  stay updated plus informed. The internet is one great platform for the  same. There are many medical videos, articles, papers, websites, forums,  etc which can help us protect ourselves and live a healthy life.
