  1. Brain tumor

    A brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. Other symptoms may include difficulty walking, speaking, with sensations, or unconsciousness.The cause of most brain tumors is unknown. Uncommon risk factors include exposure to vinyl chloride, Epstein–Barr virus, ionizing radiation, and inherited syndromes such as neurofibromatosis, tuberous sclerosis, and von Hippel-Lindau Disease. Studies on mobile phone exposure have not shown a clear risk. The most common types of primary tumors in adults are meningiomas (usually benign) and astrocytomas such as glioblastomas. In children, the most common type is a malignant medulloblastoma. Diagnosis is usually by medical examination along with computed tomography (CT) or magnetic resonance imaging (MRI). The result is then often confirmed by a biopsy. Based on the findings, the tumors are divided into different grades of severity.Treatment may include some combination of surgery, radiation therapy and chemotherapy. If seizures occur, anticonvulsant medication may be needed. Dexamethasone and furosemide are medications that may be used to decrease swelling around the tumor. Some tumors grow gradually, requiring only monitoring and possibly needing no further intervention. Treatments that use a person's immune system are being studied. Outcomes for malignant tumors vary considerably depending on the type of tumor and how far it has spread at diagnosis. Although benign tumors only grow in one area, they may still be life-threatening depending on their size and location. Malignant glioblastomas usually have very poor outcomes, while benign meningiomas usually have good outcomes. The average five-year survival rate for all (malignant) brain cancers in the United States is 33%.Secondary, or metastatic, brain tumors are about four times as common as primary brain tumors, with about half of metastases coming from lung cancer. Primary brain tumors occur in around 250,000 people a year globally, and make up less than 2% of cancers. In children younger than 15, brain tumors are second only to acute lymphoblastic leukemia as the most common form of cancer. In NSW Australia in 2005, the average lifetime economic cost of a case of brain cancer was AU$1.9 million, the greatest of any type of cancer.

  1. brain tumor

    A brain tumor refers to an abnormal growth of cells in the brain, which can be either benign (non-cancerous) or malignant (cancerous). The tumors can originate in the brain directly, known as primary tumors, or they can begin elsewhere in the body and spread to the brain, known as secondary or metastatic tumors. The presence of a brain tumor can disrupt normal brain function due to the pressure it exerts on certain areas of the brain or due to the invasion of and damage to healthy brain tissue. Symptoms may vary depending on the tumor's size, type, and location.

  1. Brain tumor

    A brain tumor, or tumour, is an intracranial solid neoplasm, a tumor within the brain or the central spinal canal. Brain tumors include all tumors inside the cranium or in the central spinal canal. They are created by an abnormal and uncontrolled cell division, usually in the brain itself, but also in lymphatic tissue, in blood vessels, in the cranial nerves, in the brain envelopes, skull, pituitary gland, or pineal gland. Within the brain itself, the involved cells may be neurons or glial cells. Brain tumors may also spread from cancers primarily located in other organs. Any brain tumor is inherently serious and life-threatening because of its invasive and infiltrative character in the limited space of the intracranial cavity. However, brain tumors are not invariably fatal, especially lipomas which are inherently benign. Brain tumors or intracranial neoplasms can be cancerous or non-cancerous; however, the definitions of malignant or benign neoplasms differs from those commonly used in other types of cancerous or non-cancerous neoplasms in the body. Its threat level depends on the combination of factors like the type of tumor, its location, its size and its state of development. Because the brain is well protected by the skull, the early detection of a brain tumor occurs only when diagnostic tools are directed at the intracranial cavity. Usually detection occurs in advanced stages when the presence of the tumor has caused unexplained symptoms.

  4. Paul Northcott:

    Paul Northcott was the one of the first recipients of the AACR NextGen grant for transformative cancer research, a grant mechanism intended to support creative cancer research that may not be funded through conventional channels. Northcott’s research studies the molecular and genetic level of a type of childhood brain cancer called medulloblastoma, the most common malignant brain tumor in children, with five-year survival rates ranging from 30 to 80 percent. Through Paul Northcott research, Paul Northcott discovered molecular subgroups of medulloblastoma with distinct patient features, outcomes and mutational patterns. These findings changed the way the disease is studied, diagnosed and the way patients are treated, Paul Northcott said. There are no clinical compounds or FDA-approved drugs so I think the biggest challenge over the next several years is to take that information that we've gleaned from the genomics era and actually translate that into better treatment options for patients.

  5. Rusty Monhollon:

    I just got done with MRI. They said I have a brain tumor, and it’s something that’s on your brain. And it’s called tumors. And they get bigger and bigger. So you have to take these pills.
