What is cervical cancer?? |
What is cervical cancer?? Cancer is a disease in which abnormal malignant body cells uncontrollably grow and multiply. Cervical cancer is characterized by the presence of many abnormal, malignant (cancerous) cells in the cervix. The cervix forms the bottom part of a woman鈥檚 uterus, connecting it to the vagina. Cervical cancer is one of the most common types of women鈥檚 reproductive cancers. In the body, healthy cells divide and grow in a regulated manner. Healthy new cells replace aging, dying cells. Cancer cells, however, continue to divide in an unregulated manner until they form a mass called a tumor. Tumors may remain within the cervix or can spread to surrounding tissue, including organs and distant regions of the body. Symptoms of cervical cancer typically appear only when the cancer begins to invade nearby tissue, such as the vagina. When this occurs, the most common symptom is irregular vaginal bleeding. A major risk factor for cervical cancer is exposure to a group of common sexually transmitted viruses called human papillomavirus (HPV). There are more than 100 types of HPV but only a few of them have been associated with causing cervical cancer. In addition, many women are exposed to HPV, but only a small percentage of them develop cervical cancer. Other risk factors for cervical cancer include exposure to other sexually transmitted diseases such as chlamydia and human immunodeficiency virus (HIV), having multiple sexual partners, smoking and the use of birth control pills. There's excellent information at the women's site below! http://obgyn.health.ivillage.com/obgynca... The cervix is the lower part of the uterus (womb). The upper part, or body, of the uterus, is where a fetus grows. The cervix connects the body of the uterus to the vagina (birth canal). The part of the cervix closest to the body of the uterus is called the endocervix. The part next to the vagina is the ectocervix. Most cervical cancers start where these 2 parts meet. Cancer of the cervix (also known as cervical cancer) begins in the lining of the cervix. Cervical cancers do not form suddenly. Normal cervical cells gradually develop pre-cancerous changes that turn into cancer. Doctors use several terms to describe these pre-cancerous changes, including cervical intraepithelial neoplasia (CIN), squamous intraepithelial lesion (SIL), and dysplasia. There are 2 main types of cervical cancers: squamous cell carcinoma and adenocarcinoma. Cervical cancers and cervical precancers are classified by how they look under a microscope. About 80% to 90% of cervical cancers are squamous cell carcinomas, which are composed of cells that resemble the flat, thin cells called squamous cells that cover the surface of the endocervix. Squamous cell carcinomas most often begin where the ectocervix joins the endocervix. Cervical cancer is just that-- cancer or a malignancy of the cervix (the bottom end of the uterus that connects the vagina and uterus). It has been shown in most studies to be caused by the HPV virus. Cervical cancer can be detected by a pap smear at the gynocologist. See my source for more information. http://en.wikipedia.org/wiki/cervical_ca... Cervical Cancer The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. Cervical cancer is caused by several types of a virus called human papillomaviruses (HPV). The virus spreads through sexual contact. Most women's bodies are able to fight HPV infection. But sometimes the virus leads to cancer. You're at higher risk if you smoke, have many children, use birth control pills for a long time, or have HIV infection. Cervical cancer may not cause any symptoms at first, but later, you may have pelvic pain or bleeding from the vagina. It usually takes several years for normal cells in the cervix to turn into cancer cells. Your health care provider can find abnormal cells by doing a Pap test - examining cells from the cervix under a microscope. By getting regular Pap tests and pelvic exams you can find and treat changing cells before they turn into cancer. http://www.nlm.nih.gov/medlineplus/cervi... Cancer in the uterus, thats why we woman need to go once a year to the gynecologist in order to prevent to get that kind of cancer. |
