    factor in determining the response of brain tumors to chemotherapy, radiation, and surgery. Patients over sixty years old have a lower response rate and shorter duration of response than younger patients. Tumor cells from younger patients were sensitive to BCNU, but cells from older patients barely responded to the BCNU. Only a few studies evaluate age as a parameter of response. Older patients may have to take medicine due to chronic illnesses, and this means that there should be special attention to those patients because the drugs could mess up the treatments. Also, older patients have a decreased creatinine clearance that must be considered when calculating the dose of the chemotherapeutic drug (Medscape). Headaches…

    A brain tumor is an abnormal growth of cells within the brain, which can be cancerous or non-cancerous (benign). It is generally caused by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs…

    a shape feature extraction of MRI brain tumor image retrieval. We used T1 weighted image of MRI brain tumor images. There are two modules: feature extraction process and classification. First, the shape features are extracted using techniques like Scale invariant feature transform (SIFT), Harris corner detection and Zernike moments. Second, the supervised learning algorithms like Deep neural network (DNN) and Extreme learning machine (ELM) are used to classify the brain tumor images. Experiments…

    A brain tumor or intracranial neoplasm occurs when abnormal cells form within the brain. There are two main types of tumors: malignant or cancerous tumors and benign tumors. Secondary or metastatic brain tumors are more common than primary brain tumors, In children younger than 15, brain tumors are second only to acute lymphoblastic leukemia as a cause of cancer. In Australia the average economic cost of a case of brain cancer is $1.9 million, the greatest of any type of cancer. Signs and…

    A brain tumor is a mass of tissue that is formed by an increase of abnormal cells (Web MD). When cells in your body die, they normally get replaced by new cells. However, if the brain has a tumor or any type of cancerous cell, this will be affected and new cells may not grow. Most tumor cells increase in size and unlike regular cells in the body, they do not die. There are two types of brain tumors; the first is Malignant Brain Tumor, this forms within the brain and is common that the tumor will…

    With a fascination of the brain since middle school, I have gradually developed an interest in neurology, especially concerning the study of brain tumors. It is fascinating to know that one tumor in the brain can affect the entire body, which is why I wish to embrace the profession of a neurologist in the future. As a dedicated student, I am always centered around the “why” of any situation whether it be in science, history, or math. I dig deeper and focus on the roots of the problem being…

    Metastatic Brain Tumors

    • 523 Words
    • 3 Pages

    Cancer cells can break away from the primary tumor site and travel through blood and lymphatic vessels. This is how cancer cells spread, or metastasize, to another part of the body, such as the brain. These tumors can develop when a patient’s primary cancer, while still undetectable at its original site, sends out metastatic cells that travel to the brain and establish themselves there. Most cancer patients are actually at risk of having their tumor spread to multiple sites. …

    Pediatric brain tumors have always been a great interest of mine. I find it devastating hearing the news of a child with a brain tumor because often times they are fatal. The complexity of brain tumors and the impact they play on the functions of one’s body are life changing. For this reason, I was interested in researching a charity that raises money to find a cure or prevention for brain tumors in children. The two organizations I chose to research were American Brain Tumor Association,…

    Usually, when children have malignant brain tumors, they will need radiation therapy to try to stop the malignant cells from spreading. Doctors try their hardest to postpone radiational therapy in children as it may generate long-term brain effects. When radiation therapy is used, the radiational energy transmitted to the tumor area can affect abnormal tissue as well as normal tissue, which can induce problems. The more tissue area that the doctors choose to radiate, the higher the chance…
