Surface epithelial-stromal tumor

hard one but, with the help from your doctors and the knowledge you can get through this. Carcinoma is a cancer that develops from the epithelial cells, which begins in the tissue that lines the outer and inner surface of the body. Breast cancer is a growth of mutated cells that forms in the lobules, the ducts, and also the stromal tissue of the breast. Stromal tissue is the fatty fibrous tissue that holds and supports the breast. The cause of these mutated cells is the change in the genes that

Epithelial tumors about ninety percent of ovarian cancer develop in the epithelium, which is the thin sheet of tissue that protects the ovaries. This form of ovarian cancer generally occurs in postmenopausal women. Germ cell carcinoma, making up about five percent

Loss of primary cilia occurs early in breast cancer development Background Primary cilia are microtubule-based organelles that resemble hair-like projections, which extend from the plasma membrane on many types of normal eukaryotic cells. These eukaryotic cells with primary cilia exhibit a non-motile single cilium. The structure of the cilia comprises of a basal body that is anchored into the plasma membrane to nucleate microtubules. Intraflagellar transport (IFT) regulates ciliogenesis, or ciliary

greater number of deaths (4,271 deaths) associated with it. Almost three-quarters of the ovarian cancer are diagnosed at late stages after tumors have metastasized within the peritoneal cavity. Ovarian cancer can either affect the epithelial lining of the ovaries or arise from non-epithelial origins. Approximately 90% of primary malignant tumors present as epithelial carcinomas (EC).

Cancer I am going to inform my audience about cancer and the process the disease goes through in the human body. Cancer starts when cells in the body start to grow out of control. Cancer cells grow differently than normal cells. Instead of the cells dying the cancer cells will continue grow. My goal is to succeed in this course and gain more knowledge about the disease that caused death to not only people in the world but important people in my life. I decided to research cancer because cancer

Numerous mediators of inflammation are present during the process of infection, comprising interleukin-1β (IL-1β) as well as tumor necrosis factor-α (TNF-α). Mucosal cells tissues infected by Chlamydia include the dendritic cells, the epithelial cells, fibroblast, as well as the macrophages. Toll-like receptors are expressed by these cells that identify the particular pathogen-connected molecular patterns, comprising, bacterial wall

their immunohistochemical studies (Kim et al., 2004; Choi et al., 2009; Guo et al., 2011; Wang et al., 2012). Moreover, there was a significant association between Bmi-1 expression and histopathological type, tumor grade, lymphovascular invasion, nodal metastasis, distant metastasis and tumor stage. These results confirm the intimate relation between Bmi-1 and breast cancer progression leading to aggressive behavior. These correlations are similar to results observed by Guo et al., 2011; Zhang et

With the help of chemokines, cytokines and growth factors secreted by tumor cells, macrophage are recruited to the site of tumors. These macrophages and tumor cells will then secrete IL-1 which will allow angiogenesis, matrix remodeling, metastasis and invasion to occur, resulting in tumor progression. [1] Leptin and IL-1 are inflammatory and pro-angiogenic factors which are able to upregulate the levels of VEGF causing tumor angiogenesis and metastasis. By decreasing these factors, there is a chance

of tumorigenesis. This classical CSC model implies that every cell within the tumor has the same potential to give rise to tumorigenic cells. However, this model is not as widely accepted as the hierarchical model of CSC because most cancers are seen as a heterogeneous population of cells, not a homogenous population as the classical model proposes (Podberezin et al., 2013). The hierarchical model proposes that a tumor consists of a heterogeneous population of cells. Only a select few of the cells

develop different types of tumors. Epithelial tumors start from the cell that covers the outer surface of the ovaries. Germ cell tumors start from the cells that produce the eggs. Stromal tumors start from the structural tissues that hold the ovary together and produce the female hormones (1). Most of these tumors listed above are benign meaning that they are non-cancerous and can be either treated by removing the ovary or removing part of the ovary. Malignant tumors are cancerous and therefore
