brain cancer - types of brain cancer
metastati (secondary) brain tumors are brain tumors that that originate from cancer cells that have spread from other parts of the body. types of brain cancer ? , which expands haupt brain cancer rarely over the central nervous system. Death from the haupt brain cancer outside, is a result unsupervised tumor growth within the limited space of the skull. metastatisches brain cancer highly expanded cancer displays and has a poor prognosis. All cancerous brain tumors are life threatening (malignant) because they have an aggressive and invasive nature. , which can cause causes brain cancer ? Exposure to vinyl chloride is known to cause brain cancer . Vinyl chloride is a toxic chemical compound frequently used in manufacturing. It is a combustible, colorless gas. Vinyl chloride is also known as chloroethene, chloroethylene, and ethylene monochloride. A known human carcinogen, vinyl chloride
normally a good-like tumor is less dangerous than a malignant one. In the brain, however, either kind of tumor can become a life-threatening problem. As the tumor fills more and more of the space inside the skull and triggers swelling in the brain, pressure inside the head eventually rises to dangerous levels. Cancer can attack anywhere in the head, ranging from the skull and the membranes that cover the brain, to the nerves and tissue in the brain itself. It often starts elsewhere in the body, as lung cancer, breast cancer, or the dangerous skin cancer called malignant melanoma. brain cancer schlagmã¤nner and women over equally. The exact risk factors are unknown. Signs/Symptoms As pressure inside the head slowly rises, headaches and vomiting are likely. In roughly 25 per cent brain cancer victim, the first characters of the problem are mental symptoms such as drowsiness, lack of energy, personality changes, forgetfulness, and psychotic episodes. In others, seizures may be the initial tip-off, often preceding other symptoms by months or years. Speech, writing, and movement may be affected, depending on the location of the tumor. In some parts of the brain, a tumor can grow to a considerable size before any symptoms appear. In other areas, even a small tumor can produce noticeable and devastating results.
pituitã¤res adenoma ) may increase the secretion of hormones and cause discontinuation of menstruation (i.e., amenorrhea) and excess secretion of milk (i.e., galactorrhea) in women. Impotence may occur in men. metastatisches brain cancer bends to penetrate the brain tissue indiscriminately. Some symptoms include the following: Bleeding Headache Impaired mental function Motor dysfunction Nausea Seizures Swelling Vomiting Complications Drastic and sometimes life-threatening complications can codevelops brain cancer . Obstructed flow of cerebrospinal fluid from the third ventricle may cause sudden death. Cerebral hernia is a progressive, fatal condition in which the brain is forced through an opening in the skull.
before processing most patients with brain tumors are given steroids, which are drugs that relieve swelling (edema). You may also be given anticonvulsant medication to prevent or control seizures. If hydrocephalus (an accumulation of cerebrospinal fluid within the brain) is present, the patient may need a shunt to drain the fluid. A shunt is a long, thin tube placed in a ventricle of the brain and then threaded under the skin to another part of the body, usually the abdomen. It works like a drainpipe: Excess fluid is carried away from the brain and is absorbed in the abdomen, or in some cases, into the heart.
(malignant retinal glioma) Tuberous sclerosis (primary brain tumors) Von Hippel-Lindau disease (retinal tumor, CNS tumors) Patients with a history of melanoma, lung, breast, colon, or kidney cancer are at risk for secondary brain cancer . Exposure to vinyl chloride is an environmental risk factor for brain cancer . Vinyl chloride is a carcinogen, that is, a cancer-causing substance. It is used in manufacturing plastic products such as pipes, wire coatings, furniture, car parts, and housewares, and is present in tobacco smoke. Manufacturing and chemical plants may release vinyl chloride into the air or water, and it may leak into the environment as a result of improper disposal. People who work in these plants or live in close proximity to them have an increased risk for brain cancer . Signs and Symptoms
supporting attention (to minimize the side effects of the tumor or treatment) rehabilitation (to regain lost motor skills and muscle strength; speech, physical, and occupational therapists may be involved in the healthcare team) antibiotics (to treat and prevent infections) continuous follow-up care (to manage disease, detect recurrence of the tumor, and to manage late effects of treatment) Experimental therapies that may be used , to of brain cancer to treat cover the following : stereotactic radiosurgery - a new technique that focuses high doses of radiation at the tumor site, while sparing the surrounding normal tissue, with the use of photon beams from a linear accelerator or cobalt x-rays. gene therapy - a special gene is added to a virus that is injected into the brain tumor. An antivirus drug is then given which kills the cancer cells that have been infected with the altered virus. Long-term outlook for a person with a brain tumor: Prognosis greatly depends on all of the following
