CIN (formerly cervical dysplasia) refers to premalignant changes in the cervical epithelium that have the potential to progress to cervical cancer. The histologic features most commonly associated with cervical dysplasia include cellular immaturity, cellular disorganization, nuclear abnormalities, and increased mitotic activity. The severity of CIN is de termined by the portion of epithelium showing disordered growth and development. The changes start at the basal layer of the epithelium and can expand to encompass the entire epithelium .Cervical intraepithelial neoplasia (CIN), formerly called dysplasia, means disordered growth and development of the epithelial lining of the cervix. There are various degrees of CIN. Mild dysplasia, or CIN I, is defined as disordered growth of the lower third of the epithelial lining. Abnormal maturation of the lower two-thirds of the lining is called moderate dysplasia, or …show more content…
Severe dysplasia, CIN III, encompasses more than two-thirds of the epithelial thickness with carcinoma in situ (CIS) representing full-thickness dysmaturity. While histologically evaluated lesions are characterized using the CIN nomenclature, cytologic smears are classified according to the Bethesda system, which was most recently revised in 2001. Briefly, atypical squamous cells are divided into those of undetermined significance (ASC-US) and those in which a high grade lesion cannot be excluded (ASC-H). Low-grade squamous intraepithelial lesion (LSIL) encompasses cytologic changes consistent with koilocytic atypia or CIN I. High-grade squamous intraepithelial lesion (HSIL) denotes the cytologic findings corresponding to CIN II and CIN III. CIN may be suspected because of an abnormal cytologic
Cervical cancer is when there are malignant cells present in the cervix; it is developed in the lining of the cervix. A cervix is a narrow opening located at the bottom of the uterus that leads into the vagina. Cervical cancer mostly affects women between the ages of 40 and 55. This cancer can be prevented by screening for precancerous cells, and it can also be cured if it is detected at an early stage. Over the past few decades the number of cervical cancer cases has declined dramatically due to a more widespread screening of the disease. Today, it is estimated that 10,000 new
Cervical cancer is caused by the uncontrollable growth of cells in the cervix, the lower part of the uterus that opens into the vagina. Some signs of cervical cancer are abnormal bleeding in the vagina (between menstrual cycles, after sex, and after menopause), pain in the lower belly, pain during sex, and abnormal vaginal discharge.
Due to abnormal Pap smear, having a cone biopsy or loop electrosurgical excision procedure on the cervix
Cervical cancer is one type of cancer happening from the cervix due to abnormal growth of cells. There are many reasons to cause cervical cancer. One of them is that the abnormal cells from other parts of body are able to invade or spread to the cervix and cause the abnormal growth. Unfortunately, in early stage, typically no symptoms are seen, and later symptoms may include abnormal vaginal bleeding, pelvic pain, or pain during sexual intercourse. What’s more, when bleeding after sex, it also may indicate the presence of cervical cancer.7
The opening of the cervix is termed the cervical os. The internal part of the cervical os is termed the internal os and opens into the uterus. The external part of the cervical os is termed the external os and opens into the vagina. The cervix can be divided into two sections based on location. The cervical canal is termed the endocervix and is lined with glandular cells of columnar epithelium. The portion of the cervix that descends downward into the vagina is termed the ectocervix and is lined with stratified squamous epithelium. The area where the glandular cells meets the squamous cells is termed the squamocolumnar junction (SCJ). As women age, the SCJ recedes back into the endocervical canal as columnar cells undergo squamous metaplasia. Right next to the SCJ is the area termed the transformation zone. This transformation zone is where HPV has its negative, carcinogenic
Previous reports suggested that p16INK4a immunostaining allows precise identification of even small cervical intraepithelial neoplasia (CIN) or cervical
Is a cancer arising from the cervix it's due to the abnormal growth cell that have ability to invade or spread to another. cervix cancer does not have any alternate names .what causes cervix cancer is human papillomavirus infection having too many sexual partners , smoking , taking birth control pills , and engaging in early sexual contact . hpv infections may cause cervical dysplasia or abnormal growth of cervical cells .
Abnormal changes on your cervix are likely caused by HPV. The changes may be minor (low-grade) or serious (high-grade). Most of the time, minor changes go back to normal on their own. But more serious changes can turn into cancer if they are not removed. The more serious changes are often called “precancer” because they are not yet cancer, but they can turn into cancer over time. It is important to make sure these changes do not get worse.
Cervical cerclage is a term refers to the treatment of cervical incompetency or cervical insufficiency, during pregnancy the cervix begins to shorten and open too early cause premature birth or late miscarriage. The weakening of the cervix occurs as a result of cone biopsy or loop electrosurgical excision procedure that had been previously performed on the pregnant patient, a history of miscarriages that occurred in the second-trimester or when damage to the cervix by pregnancy termination is done. The best time to have cervical cerclage procedure done is at 12- 14 weeks in the third month of pregnancy or later when the cervix shortens or opens. Future pregnancies will probably require the cervical cerclage procedure done.
There are usually no symptoms or signs of CIN, and the diagnosis is most often based on biopsy findings following an abnormal routine cervical cytology smear. Because high-grade dysplasia probably is a transitional phase in the pathogenesis of many cervical cancers, early detection is extremely important. Based on the American Cancer Society guidelines, which were last revised in 2002, all women who have reached age 21 years, or who are 3 years past coitarche, should have a pelvic examination and collection of a cytologic smear. The cervical cytology smear should be performed annually in case of conventional Papanicolaou (Pap) smears, and biannually if using liquid-based cytology. Once a patient is age 30 years or older and has had 3 consecutive
Cervical cancer has a major impact on women’s lives; it is the second most common cause of cancer-related diseases and death among women worldwide. According to the Center for Disease Control and Prevention (2010), cervical cancer is the cancer that forms in tissues of the cervix. The cervix is the lower, narrow end of the uterus that connects the vagina to the upper part of the uterus. Cervical cancer is a slow-growing cancer that may not cause any symptoms at first but may cause pelvic pain or bleeding from the vagina later. It is mostly caused by a human papillomavirus (HPV) infection. HPV is a common virus that is passed from one person to another during sexual activity (Center for Disease Control and Prevention [CDC], 2010).
This theory is supported with the evidences provided by the findings of previous researches. For example, In 2003, Okino, K et al found that in 11 of 15 the patients, there was an excessive expression of DVL 1 shown in cervical squamous cell
Human Papillomavirus is a sexually transmitted disease that infects over twenty million Americans each year (Vanslyke, Baum, Plaza, Otero, Wheeler, Helizter, 2008, P. 584). Many of these people do not realize that they are infected because they do not show any symptoms. Even though HPV has been talked about for decades, it is only until recent years that the topic has become part of mainstream women’s health issues. Not only that, many of these people are women who do not understand the importance of testing for HPV. HPV is one of the leading causes of cervical cancer among women.
Among the 12, 200 new cases of cervical cancer ninety-percent of them are caused or attributed to HPV (ACS).
Cervical cancer malignant cancer of the cervix uteris or cervical area. It may present with vaginal bleeding but symptoms may be absent until the cancer is in its advanced stages, which has made cervical cancer the focus of intense screening efforts using the Pap smear. About 2.2 percent of women carry one of the 2 virus strains most likely to lead to cervical cancer. One of the symptoms of Cervical Cancer is very Unusual amount of discharge.
