Pathophysiology: This topic talks about the testing, diagnosis, and treatment of cervical cancer. For general information about abnormal Pap test results, see the topic Abnormal Pap Test. Cervical cancer occurs when abnormal cells on the cervix grow out of control. The cervix is the lower part of the uterus that opens into thevagina. Cervical cancer can often be successfully treated when it's found early. It is usually found at a very early stage through a Pap test. Cervical cancer is one of the most common cancers in women worldwide. But in the United States and other countries where cervicalcancer screening is routine, this cancer is not so common.1 Most cervical cancer is caused by a virus called human papillomavirus, or HPV. You can get HPV by having sexual contact with someone who has it. There are many types of the HPV virus. Not all types of HPVcause cervical cancer. Some of them cause genital warts, but other types may not cause any symptoms. Most adults have been infected with HPV at some time. An infection may go away on its own. But sometimes it can cause genital warts or lead to cervical cancer. That's why it's important for women to have regular Pap tests. A Pap test can find changes in cervical cells before they turn into cancer. If you treat these cell changes, you may prevent cervical cancer. Abnormal cervical cell changes rarely cause symptoms. But you may have symptoms if those cell changes grow into cervical cancer.Symptoms of cervical cancer may include: • Bleeding from the vagina that is not normal, such as bleeding between menstrual periods, after sex, or after menopause. • Pain in the lower belly or pelvis. • Pain during sex. • Vaginal discharge that isn't normal. As part of your regular pelvic exam, you should have a Pap test. During a Pap test, the doctor scrapes a small sample of cells from the surface of the cervix to look for cell changes. If a Pap test shows abnormal cell changes, your doctor may do other tests to look for precancerous or cancer cells on your cervix.
DIAGNOSIS: A Pap smear can collect abnormal cells that are then identified in a lab. An HPV test may be performed on the sample to check for the virus and to ascertain whether high-risk or low-risk strains are present. A colposcopy is an in-office procedure that allows your doctor to view your cervix with a special magnifying tool. A solution is applied to the surface of your cervix to illuminate any abnormal cells, and your doctor can then take a small piece of tissue called a biopsy. This can be sent to a lab for a more definitive diagnosis.
STATISTICS: Every year cervical cancer is diagnosed in about 500,000 women globally and is responsible for more than 280,000 deaths annually. There is a wide variation in the incidence of cervical cancer across the globe. In the west, early detection through regular screening has aided to significantly control the prevalence of this disease, thereby, lowering its incidence. 80% of the new cervical cancer cases occur in developing countries, like India, which reports approximately one fourth of the world's cases of cervical cancer each year. The number of deaths due to cervical cancer is estimated to rise to 79,000 by the year 2010. In urban areas, cancer of the cervix account for over 40% of cancers while in rural areas it accounts for 65% of cancers as per the information from the cancer registry in Barshi.

Classically, the 3âuntranslated region (3âUTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3âUTR alone, without all other elements in mRNA such as 5âUTR and coding region. The importance of independent 3âUTR RNA (referred as I3âUTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3âUTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3âUTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3âUTR were important for its tumor suppression activity. Then, the C/EBP 3âUTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3âUTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3âUTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990âs to 2000âs, world scientists found several 3âUTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3âUTR regions, although the existence of their transcribed products as independent 3âUTR RNAs is still to be confirmed. Our studies indicate that the independent 3âUTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
