Anal tumor is a standout amongst the most aggressive variety of cancer‚ particularly if not detected in its initial stages. Its uncomplimentary location‚ which makes it an unthinkable for a large number of people‚ is yet another reason behind why this tumor is frequently ignored. What Is Anal Tumor? Anal malignancy grows at the opening of the rectum (anus) from a lump which is made by the unusual and uncontrolled development of cells in the anus. Despite the fact that it’s rare‚ it’s often disregarded

About Uterine Fibroids By Dr Ariana Martins Sep 26‚ 2015 Uterine fibroids are tumors commonly found in the uterus of a woman. Most women having uterine fibroids are not even aware of the same and can carry on with their daily routine without feeling any kind of pain or discomfort. However‚ it can be daunting for some when they find out about the presence of these fibroids in the uterus especially if you are trying to conceive a child. Those diagnosed with having uterine fibroids should not be worried

Radiation therapy (RT) is an essential component in the interdisciplinary treatment of brain tumors. Independently of histology‚ radiation plays a central role and has shown to increase local tumor control. Developments in radiation oncology are always aiming at an increase precision of dose delivery: More conformal coverage of target volumes‚ steep dose gradients to surrounding tissues‚ and sparing of organs at risk (OAR). In photon therapy‚ based on 3D-RT‚ stereotactic radiotherapy was a big step

suggested the relationship between PRL and CNS tumors. Ciccarelli et al reported in 2001 that high PRL levels and increased PRL receptors were found in some of the patients with meningiomas and schwannoms‚ indicating that PRL might be involved in the growth of the two benign intracranial tumors [9]. The later study by Leães et al in 2007 showed that hyperprolactinemia‚ intracellular PRL and its receptor were common findings in patients with primary CNS tumors such as meningioma‚ glioblastoma‚ astrocytoma

Primary Source: Tumor Microenvironment Topic Summary Cancer has become one of the world’s leading trends in diseases‚ both in discussion and in medicinal related research. Major insights and discoveries within cellular biology can be accredited to the drive of understanding and curing cancer. The battle of cancer began to rise in public attention around the era of Henrietta Lacks‚ who provided the world’s first immortal cell line. Most research of the time‚ and even up to the past decade‚ was targeted

and divide uncontrollably. Cancer in situ is a tumor located in its place of origin. Malignant tumors establish new tumor distant from the primary tumors. Cancer cells characteristics distinguish them from normal cells. They have abnormal nuclei with many chromosomal irregularities. They form tumors because they do not exhibit contact inhibition. They induce angiogenesis and cause nearby blood vessels to form a capillary network that services the tumor. Normal cells can undergo the cell cycle for

with widespread progression that leads to respiratory failure. Tumor invasion and metastasis is multistep complex process in which tumor cells alter cell–extracellular matrix (ECM) interactions at the primary tumor site to invade adjacent tissues and thus translocate through the vasculature to other systems to form secondary tumors there. A family of proteolytic enzymes called MMPs are the key proteases playing an important role in tumor invasion and metastasis by degrading the ECM and basement membrane

a higher survival rate due to a higher status of overall health. (Furuya) Ovarian cancer manifests itself in the form of epithelial tumors that develop on the exterior of the ovaries. Their growth is hasty and cancer cells migrate quickly by direct extension into organs within close proximity and through circulating blood and lymph. The development of these tumors can be related to a response initiated through excessive estrogen exposure. (Ignatavicius) Symptoms generally include abdominal pain

2: Using the Scientific Method Protocol: Background information: Tumor cells are cells that are able to divide and generate new cells at uncontrolled rates. Therefore‚ in a short amount of time‚ a single mutated tumor cell can produce many other tumor cells. These cells can eventually take over the human body‚ resulting in death. But‚ for these tumor cells to survive‚ they need nutrition and oxygen just like normal cells. Tumor cells are interesting in that they can release a substance – a protein
