Serous tumour - Citizendia

Serous tumours are part of the surface epithelial-stromal tumour group of ovarian neoplasms. See also Ovarian cancer Surface epithelial-stromal Tumors are a class of ovarian neoplasms that may be Benign or Malignant. Ovarian cancer is a cancerous growth arising from an Ovary. The cancer most commonly forms in the lining of the ovary (resulting in epithelial They are common neoplasms with a strong tendency to bilaterality, and they account for 30% of all ovarian tumours. Sixty percent are benign, 10% are borderline and 30% are malignant. Malignant (from the Latin roots mal- = "bad" and -genus = "born" is a medical term used to describe a severe and progressively worsening disease

Explanation

Benign serous tumours are unilocular (have one lobe); however if very large may be multilocular, contain clear fluid and have a smooth lining composed of columnar epithelial cells with cilia. In biology and medicine epithelium is a tissue composed of cells that line the cavities and surfaces of structures throughout the body A cilium (plural cilia) is an Organelle found in eukaryotic cells Cilia are tail-like projections extending approximately Surgery is curative. In borderline lesions, the cyst or surface is lined by papillary structures, which are often very complex. Surgery is usually curative. Microscopically, stromal papillae are covered by atypical epithelial cells, but stromal invasion is absent, nuclear stratification is present. A microscope ( Greek: ( micron) = small + ( skopein) = to look or see is an instrument for viewing objects that are In biology and medicine epithelium is a tissue composed of cells that line the cavities and surfaces of structures throughout the body Malignant serous tumours are solid, may be cystic and often show hemorrhage and necrosis. Bleeding, technically known as hemorrhaging / haemorrhaging (see American and British spelling differences) is the loss of Blood from Necrosis (in Greek Νεκρός = "dead" is the name given to unnatural Death of cells and living tissue. They are lined by a complex papillary pattern with presence of nuclear anaplasia. Serous carcinomas often have bulky peritoneal and omental metastases, and spread to the lymph nodes is frequent. In higher Vertebrates the peritoneum is the Serous membrane that forms the lining of the abdominal cavity &mdash it covers most of the intra-abdominal Metastasis ( Greek: displacement μετά=next + στάσις=placement, plural metastases) sometimes abbreviated mets, A Lymph node ( lɪmf noʊd is an organ consisting of many types of cells and is a part of the Lymphatic system.

Unsurprisingly, 5-year survival decreases as the stage increases. There is a 25% survival rate with a stage III serous carcinoma. In Biostatistics, survival rate is a part of Survival analysis, indicating the percentage of people in a study or treatment group who are alive for a given period Staging:

Stage I - Tumor growth limited to ovaries. Stage II - Growth involving one or both ovaries with pelvic extension. Stage III - Tumor involving one or both ovaries with implants outside pelvis. Stage IV- Tumor involving one or both ovaries with presence of distant metastasis.
