In the developing countries of Africa, Latin America, Central and South-East Asia, cancer of the uterine cervix leads other tumor malignants. Squamous dysplasia which is also abbreviated as CIN is a spectrum of intraepithelial changes of indistinct precincts that starts with placid atypia and develops through stages of distinctly marked intraepithelial deformities to carcinoma in situ. The range of classes and forms points on a disease variety but not separate malady entities. They are predecessor lesions to persistent squamous cell carcinoma. Dysplasia is a potentially unalterable change typified by an augment in mitotic rate, an atypical cytological feature which is by shape, size, nuclear appearance and abnormal organization that might be by cellularity,2 isolation and or polarity that fall short of premalignant change. In most instances, dysplasia might develop to cancer and or dysplastic changes might be established closest to foci of tumor. 3. Clinical features The characteristics of CIN lacerations are white patches that appear on the cervix preceding an application of acetic acid around the cervix. Distinctive vascular patterns can be noted on colposcopic assessment of the cervix in soaring grade CIN. Lacerations appear on the frontal lip twice as usually as the subsequent lip. These can be found in the transformation areas and zones around squamous metaplasia at the endocervix. This might stop instantly at the intersection with the native portion squamous epithelium, however this can continue along on the whole endocervical passage. It is common that the part of CIN on the portio area is low grade CIN 1 while the portion that broadens into the endocervical passage is high grade CIN 2 and 3. Clinical indicators show that carcinoma symptoms depend on the magnitude and phase of the tumor. Those patients who have lumps confined to the cervix are usually asymptomatic and are easily detected due to uncharacteristic Pap smear result. On the other hand, patients with clinically notable tumors present various degrees of unusual bleeding. At an early stage lesions might be indurate or ulcerated while more highly developed tumors form exophytic fungating sufficient and or endophytic ulcerated or even infiltrative lots capable to produce an enlarged cervix that is hard or barrel-shaped. Picture showing an ulcerated fungating carcinoma on the cervix Uncharacteristic cellular propagation, maturation and atypia portray CIN. Nuclear deformity is the characteristic of 3CIN and includes pleomorphism, hyperchromasia, abnormal chromatin distribution, and irregular borders. These nuclear deformities continue all the way through the epithelium despite maturation of cytoplasmic towards the exterior. As such, mitotic rate is amplified and abnormal mitotic features might be noted. 4. Pathology Grossly, squamous cell carcinoma of the cervix is normally characterized by focal or discharge polypoid gel of the endometrium by tender, friable, grey-white fiber. Massive tumours might form confluent tissue growths to occupy the endometrial cavity. Attacks of the underlying myometrium and or invasion of the cervix might be noted. ...Download file to see next pagesRead More

Small Cell Carcinoma Tumors

...needle aspiration (FNA) specimens, both transthoracic and transbronchial, varying quantities of tissue fragments and single cells linked with apoptotic bodies and necrotic debris were observed. The loss of chromatin pattern can be induced by the degenerative changes, making the nuclei pale-staining with haematoxylin. Moreover, almost 50% of the reported cases of small cell carcinoma have areas affected by urothelial carcinoma, particularly andenocarcinoma and squamous cell carcinoma (Devilee & Tavassoli 135). The existence of these differentiated areas concurs with the diagnosis of small cell...

Stem Cell

...?The Boon of Stem Cell Donation I. Introduction For ages, humankind was beset by a number of diseases and illnesses that seemed to be the primary reason for difficulty and death. It was thought then that no solution will ever come as lifetime meant constant struggling and suffering. Until finally, a ‘manna from heaven’ arrived and proved to be a powerful solution: stem cell. This discovery was not only a medical breakthrough, but it is also considered as a miracle for all generations and civilizations. So everything went back to the cell. As the basic unit of life, the cell became the determinant for the cause of several serious medical conditions, such as heart failures, birth defects and all types of cancer. An understanding... of the...

...% are commonly detected (Berg, et al., 2002). It is essential to detect minute quantities of a specific protein molecule in the presence of several other protein molecules, like for instance the presence of viral proteins in blood circulation. Very minute quantities of a protein molecule of interest concern in a cell or in the human blood can be determined by an immunoassay procedure which is called Western blotting. A sample is subjected to electrophoresis on an SDS-polyacrylamide gel. Blotting or more commonly called electroblotting moves the resolved protein molecules on the SDS-polyacrylamide gel to the surface of a polymer sheet in order to have the proteins more obtainable during the reaction. A specific antibody...

Population Screening For Cervical Cancer

...Population Screening For Cervical Cancer Cervical cancer and its cytologic precursors are conditions that affect sexually active women, especially in their reproductive years (Hartman et al, 2002).This condition, also known as squamous cell carcinoma of the cervix, is one of the most frequent cancers worldwide. An estimated 470,000 new cases occur worldwide each year, with the bulk of these coming from the developing countries (Boking, 2003, p.6). In the United States alone approximately 12,800 new cases of cervical cancer are diagnosed and almost 4,800 deaths recorded annually (Hartman et al, 2002). For the UK, the NHS Cancer Screening Programme reports that 900 women...

Cell Structure

...Comparison of Plant Cells and Animal Cells The most significant similarity between plant cells and animal cells is that they are both eukaryotic. Ofthe two classes of cell types eukaryotic and prokaryotic, all plants and animals are composed of cells from the former group while all bacteria and cyanobacteria fall into the later group. The macromolecular components of the prokaryotic cell are relatively basic compared to their eukaryotic counterparts. Eukaryotic cells in contrast are much more complex and take a longer time to replicate during cellular division. One defining feature of the eukaryotic...

...from histological findings has been analysed to show correlation between biological factors and patient survival. The main hypothesis tested is to show the existence or absence of any differences between two histological features to the patients' clinical treatment and outcome: Invasive lobular carcinoma (ILC) and Invasive ductal carcinoma (IDC). The aim was first to establish risk factors and use them as variables for patient survival through the time of the test. This approach has the potential of producing quantifiable risk factors that can help clinicians to design different clinical management strategies based on easy and fast diagnostic procedures. In this article, we will try to elucidate the...

Hematocellular carcinoma-Liver cancer

...Hepatic Cellular Carcinoma (Liver Cancer) When using the term ‘liver cancer’, it is important to be able to differentiate between cancer of the hepatocytes (liver cells) and cancer which has metastasized in the liver which may be called secondary liver cancer. This is often the case when a patient has breast, lung, stomach, pancreas or colon cancer and the cancer is able to spread (metastasize) to other parts of the body. In the case of Hepatic Cellular Carcinoma, the origin of the cancer is actually within the liver itself. The purpose of this discussion, is to examine thoroughly, the topic of liver cancer or what is known as Hepatic Cellular Carcinoma. The...

Invasive ductal carcinoma

...of cancer initiation. The researches in previous decade have offered support to the ideas of Virchow; that malignant tissues formed during cancers create an inflammatory microenvironment (Balkwill & Mantovani, 2001). Breast cancers arise from the epidermal lining of the terminal duct lobular unit. Cancerous cells either remain confined to the terminal duct lobular unit and the draining duct; or proliferate beyond the basement membrane to the adjacent tissue. While the former is referred to as in situ or non-invasive; the latter is called invasive or infiltrating carcinomas. A misnomer used in the classification of invasive carcinomas was ductal and lobular carcinomas;...
