Tumor is an abnormal tissue growth which is also known as neoplasm or lesion. Brain tumor is named as primary or secondary according to the cell from which it origins. Primary tumor starts in brain and usually does not spreads to other areas. Secondary (metastatic) tumor spread to the brain from another part of body and it is always cancerous. Primary tumors are of two types i.e., benign and malignant. Benign tumor grows slowly and rarely spreads. It has a distinct boundary and becomes life threatening

A spinal tumor is an abnormal mass of tissue within or surrounding the spinal cord and/or spinal column. These cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. Spinal tumors can be benign (non-cancerous) or malignant (cancerous). Primary tumors originate in the spine or spinal cord, and metastatic or secondary tumors result from cancer spreading from another site to the spine. Spinal tumors may be referred to by the region of the spine in which

INTRODUCTION: Salivary gland tumors are a morphologically diverse group of neoplasms, which may present considerable diagnostic and management challenges for the pathologist and surgeon. Salivary gland tumors are rare with an overall incidence in the western world of about 2.5 to 3.0 per 100,000 per year. About 80% of all lesions are benign; hence salivary malignancies are particularly rare, comprising less than 0.5% of all malignancies and about 5% of cancers in the head and neck. (1) Most of

My Brain Tumor "I am not an animal, I am a human being!"  - The Elephant Man I am different, so accept me. Even though I have physical disabilities I am still a human being. When I was four I had a brain tumor. The surgery left me with a paralyzed arm, crossed eye and a deaf ear. To make matters worse, the paralyzed arm was also my writing hand and I had to learn to be right-handed. When I was transferred from North Shore Hospital to Rusk Institute for Rehabilitation in New York City, I

1.1 General background The definition for “tumor” has undergone several changes largely due to scientific advancement in our understanding of cancer and the ability to differentiate one form from another. Tumor originally applied to the swelling caused by inflammation, but the non-neoplastic usage of tumor has almost vanished; thus, the term is now equated with neoplasm, and sometimes interchangeably used with the term cancer. Currently, a tumor is generally defines as an abnormal mass of tissue

Brain Tumors and Work Going Home after a brain tumor or lesion can be exciting, joyous, and fearful for the whole family. It can be hard to leave the security of your doctors and nurses, even though they are only a phone call away. Luckily social services can help homecoming along with the many laws protecting people with disabilities. Employment The workforce includes many individuals with psychiatric disabilities who face employment discrimination because their disabilities are

The Effects of a Tumor on the Family Members A tumor that is specifically in the frontal cortex can cause many changes physically and emotionally which can affect the way you interact with your family. Some of the functions of the frontal lobe are attention, abstract thought, problem solving, intelligence, creative thought, initiative inhibition, judgment, mood, major body movements, bowel and bladder control, memory and reasoning (retrieved from www.ect.org. What this means is that you

The Structure in affect brain Tumor have on people. A brain tumor is abnormal growth of tissue in the brain or central spine that can disrupt proper brain function. Doctors refer to a tumor based on where the tumor cells originated, and whether they are cancerous (malignant) or not (benign). Benign: The least aggressive type of brain tumor is often called a benign brain tumor. They originate from cells within or surrounding the brain, do not contain cancer cells, grow slowly, and typically have clear

A Brain Tumor is a mass of abnormal cells that vary in size. They can also be classified as Benign or Malignant. Benign Tumors are non-cancerous, and have definite borders that make removal of the entire mass possible. On the other hand, Malignant (Cancerous) Brain Tumors spread, aggressively invading nearby tissue, and have a higher chance of recurring after surgical removal. There are two types of Malignant Brain Tumors: Primary, and Secondary (Metastatic). Primary Brain Tumors begin in the brain

Brain Cancer Malignant Brain Tumors are defined as cancer within the central information center of the body. Cancer within the brain varies in type and the tumors are usually named after the tissue type they begin forming in. Some of the different types of brain cancers are meningioma’s, pituitary adenomas, and primitive neuroectodermal tumors ‘’or’’ medullablastomas, vestibular schwannomas and gliomas. Subtypes of gliomas include, ependymomas, astrocytoma’s, choroid plexus papilloma’s, oligodendrogliomas

Tumors or Lesions to the Hypothalamus Patient The Hypothalamus is a small area near the base of the brain just ventral to the thalamus. It has widespread connections with the rest of the forebrain and the midbrain. Partly through nerves and partly through hypothalamic hormones, the hypothalamus conveys messages to the pituitary gland, altering its release of hormones (Kalat, 2003). Any type of damage to a hypothalamic nucleus, such as tumors or lesions, may lead to abnormalities in

you have an abundant knowledge of brain tumors and cancer? Have you or a loved one ever had a brain tumor of any sort? If so, they are very harmful and deadly. Over the course of time with the improvement of technology, treatment will be easier and symptoms won't be as noticeable. Brain tumor research has improved exceedingly, therefore, if John Gunther’s son was alive today, he most likely could have been successfully treated or cured of his brain tumor without the struggle of a death sentence

What Are Brain Tumors? “A brain tumor is a mass or growth of abnormal cells in your brain or close to your brain.” (Mayo Clinic, 2014) Brain tumors are one of the leading causes of death in children and young adult under the age of twenty. There are over one hundred and twenty different types of brain tumors. My best friend from the third grade, Sahazan, was recently diagnosed with a brain tumor, inspiring me to do my research project on this specific subject. Her condition is rapidly growing, leaving

Brain Tumors and How They Affect Different Locations of the Brain The effects of a brain tumor are diverse depending on where it is located. This is because there are four lobes in the brain and each lobe controls different functions. To some people this topic may seem soporific or recondite. However, learning about how a tumor forms, the symptoms it can cause, and the different ways to get rid of it can be exciting and lucid. The exact cause of a tumor is an enigma, but scientists have scrutinized

doctor found a benign, tumor within my friend’s brain at the age of thirteen, but he is now twenty-four years old and as healthy as ever. My father is the other person I know who had a tumor. A team of doctors found his tumor when he was thirty-nine years old; I was only four years old at the time. His was also benign but it was within a different spot of his brain, unfortunately he passed away twelve years after he found out he had it. What are brain tumors? Brain tumors are masses of cells that

The Cushing Brain Tumor Registry located at the Yale School of Medicine in New Haven, Connecticut represents an embodiment of Harvey Cushing's passion for managing the database and interpreting information. He hoped for students studying in the areas of neurosurgery, neuropathology, and neuroscience to have access to the archive. Without the help of Dr. Louise Eisenhardt and Dr. Percival Bailey collaborating and contributing to the registry, much of what is seen in the registry today would not have

A Brief look at the Physiological Basis and Neurological Effect of Brain Tumors I've always been interested in medicine, and more specifically, in surgery, but I never really knew which realm of surgery appealed to me the most. So I set out on a quest to find where my future in medicine may lay. I spent time with an orthopedic surgeon and loved the carpentry-like style of the trade, and I spent a week with a general surgeon and watched him fix hernias and cut out moles. But the surgery that

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

tools of segmentation or morphology for brain tumor segmentation~cite{Moon} or atlas based multi-label brain tumor segmentation (GLISTR)~cite{Gooya}. For multi-label brain tumor segmentation, several researchers used either feature extraction or random forest or Markov Random Field (MRF)~cite{Reza,Tustison,Zhao1,Festa,Bauer,Zhao,Doyle,Meier}. Some other approaches have been used atlas template for single label~cite{Warfield} or multi-label brain tumor segmentation~cite{Gooya,Gooya1,Cao}. All these
