Brain cancer is a consecutive abnormal growth of the cell in brain. Brain cancer is also known as tumor. A tumor appears in patient's brain or in nearby area of the brain. Tumors can be benign or cruel depending on how it is caused. Benign brain tumors are abnormal collections of cells that reproduce slowly and do not spread to other parts and can easily be removed. Whereas cruel brain cancers reproduce the cells and grow quickly, the borders are very hard compare to benign brain. It can be hard to remove them completely without damaging surrounding brain area. Brain cancer that originates in the brain is called primary brain tumor. It occurs at any age and can spread and destroy nearby parts of brain. There are known instances where effects of brain cancer has spread to the brain from other parts of body like breast cancer, liver cancer, lung cancer and so on. Brain cancer often occurs within the same family as inheritance is also responsible from among other causes of brain cancer.

Brain cancer symptoms can be classified with dizziness, memory problems, vision changes, confusion or troubling on concentration. Symptoms of brain cancer often include headaches that are caused due to less serious conditions such as painful headache or tension which have no link to cancer. Changes in personality, abnormal eye movements, weakness in arms and legs are all symptoms of the disease. Headaches caused by a brain tumor are often severe, associated with nausea and vomiting are usually worse in the morning. Seizures and tiredness are other symptoms of brain cancer.

Brain cancers are usually treated with a combination of surgery, chemotherapy, radiation, as well as medications that will control the symptoms of brain cancer. Brain cancer treatments are often very complex but surgical specialists of the brain, oncologists, radiation therapy, primary health care provider, dietitian and physical therapist can help to reduce existing problems. High doses of steroids are used to reduce any swelling caused by the tumor. These will often relieve some or all of the symptoms but have no effect on the tumor itself. Again, anticonvulsant medications may be used to prevent seizures. Most specialist frequently take a decision of surgery to remove as much of the cancer as possible. Treatments of metastatic cancers are those that have spread out largely depend on the location where they started. For example, a lung cancer that metastasized (i.e. spread elsewhere in body) to the brain would be treated with the same way as other lung cancers. Radiation is usually started after surgery. It frequently doesn't cure brain cancer but it can keep the tumor under control for short time duration. Some types of brain cancers may respond to chemotherapy. Advanced technology for treatment of cancers such as lasers and ultrasound for removing infected tumors are frequently resorted to. An alternative surgery is a new technique called Gamma Knife stereotactic radio surgery, where radiation beams are perfectly focused directly on the tumor. Experimental treatments are also available such as radioactive implants which are implanted inside tumor and certain new kinds of immune therapy provide better treatment of brain cancers in future.
