Various Brain Tumor Detection Techniques - Brain tumor is an abnormal mass of tissue in which some cells grow or multiply uncontrollably. Various techniques have been developed for detection of brain tumor. This paper focuses on survey of well-known brain tumor detection techniques and the applied image segmentation procedures. The main concentration is on the techniques which use image segmentation to detect brain tumor. These techniques include Magnetic Resonance Imaging (MRI), functional MRI (fMRI), Computed Tomography ( CT ) Scans and various others....   [tags: Computed tomography, tumor, MRI]

Ependymoma- Brain Tumor - ... A doctor takes a sample of cerebral spinal fluid using a needle to look for cancer cells, blood, or tumor markers. CSF is the fluid that flows around the brain and spinal cord (ASCO, n.d.). This procedure is done after the diagnosis of ependymoma and the tumor has been removed. If Ependymoma is diagnosed, the results from the spinal tap will help the doctor describe the tumor and this is called staging and grading (Boston Children’s Hospital, n.d.). Characteristics The symptoms of the disease are increased pressure, which is caused by the tumor swelling, and the pressure can cause vomiting, headaches, neck pains and irritability or other changes in behavior (ASCO, n.d.)....   [tags: childhood brain cancer, tumor]

Cancerous Tumor Neruroblastoma - Neuroblastoma is a cancerous tumor that develops from nerve tissue. It usually occurs in infants and children. Neuroblastoma is a serious disease and it can occur in many areas of the body, sometimes starting at the sympathetic nervous system. This particular system controls your heart rate, blood pressure, digestion, and some levels of hormones. Neuroblastoma can spread pretty much anywhere in the body including the bones in your face, skull, pelvis, shoulders, arms and legs. It can also spread to bone marrow, liver, lymph nodes, skin, and around the eyes....   [tags: Cancer, Nerve Tissue, Tumor, Children]

Tumor Protein 53 and its role in Ovarian Cancer - TP53, also called tumor protein 53 is a tumor suppressor gene that encodes p53 and acts as a control center for the cell to act on when stressed (Brachova). Human p53 is a nuclear phsophoprotein of molecular weight 53kDa located on chromosome 17 containing 11 exons and 10 introns (Ling). One of its primary roles is as a transcription factor and in its active state is a homotetramer comprised of four 393 amino acid residues (Joerger , The tumor suppressor p53). Another main role p53 plays is as a tumor suppressor and once activated, protects against cancer by “functioning as a sequence-specific transcription factor, through protein-protein interactions, activating cell cycle arrest, apoptosis...   [tags: tumor protein, ovarian cancer, tp53]

Genes' Response of Tumor Cells to Apigernin - We focused on genes determining the response of tumor cells to apigenin. Our results do not suggest that the ABC transporters ABCB1 and ABCB5 may play a role for apigenin resistance. Multidrug resistance caused by P-glycoprotein (MDR1/ABCB1) represents a major impediment of cancer chemotherapy. P-glycoprotein is expressed in many tumor types being either inherently resistant to anticancer drugs or acquiring resistance during chemotherapy [26].

Oncogenes and Tumor Suppressor Genes Play a Role in Cancer - There are two main types of genes that play a role in cancer: oncogenes and tumor suppressor genes. Proto-oncogenes are regular genes that can become oncogenes if mutated and an oncogene is a gene that can lead to a tumor when mutated because it causes cells to divide unrestrainedly (Heidi 2008). On the contrary, tumor-suppressor genes slow down cell division. When tumor-suppressor genes do not function properly, cells can grow as rapidly as an oncogene (Heidi 2008). Tumor-suppressor genes involve the BRCA1 and BRCA2 genes that are found in breast cells (Klugar & Park 2013)....   [tags: mutation, inherited, breast] 797 words

The genetic alterations that lead to most cancers arise in the deoxyribonucleic acid (DNA) of a somatic cell during the lifetime of affected individual. Because of these genetic changes, cancer cells proliferate uncontrollably, producing malignant tumour that invade surrounding healthy tissue. As long as the growth of tumour remains localized, the disease can usually be treated and cured by surgical removal of tumour....   [tags: Health, Diseases, The Tumor of Liver] 2308 words
