Brain cancer
Overview :
There are two types of brain tumors: primary brain tumors that originate in the brain and ****static (secondary) brain tumors that originate from cancer cells that have migrated from other parts of the body.
Primary brain cancer rarely spreads beyond the central nervous system, and death results from uncontrolled tumor growth within the limited space of the skull. ****static brain cancer indicates advanced disease and has a poor prognosis.
All cancerous brain tumors are life threatening (malignant) because they have an aggressive and invasive nature.
What are the Symptoms of Brain Cancer?
This depends upon where in the brain the cancer arises, and how big it becomes before coming to medical attention. The brain has particular areas controlling thought, sight, hearing, sensation, movement, coordination and mood. The upper brain area tends to control the more advanced thought functions, while the middle controls mood and movement and the rear (or "brain stem") stimulates breathing and heart rate.
A brain tumor can obstruct the flow of cerebrosinal fluid (CSF), which results in the accumulation of CSF (hydrocephalus) and increased intracranial pressure (IICP). Nausea, vomiting, and headaches are common symptoms.
Treatment
Treatment for brain cancer depends on the age of the patient, the stage of the disease, the type and ******** of the tumor, and whether the cancer is a primary tumor or brain ****stases. The treatment plan is developed by the oncology team and the patient.
Treatment involves any combination of surgery, radiation, and chemotherapy. Some tumors require several different surgical procedures, and some can be treated with radiation alone.
Chemotherapy
Chemotherapy is not used for benign tumors and is generally not a very effective treatment for most malignant primary brain tumors or ****static tumors.
The effectiveness of chemotherapy depends on the tumor type (medulloblastomas, anaplastic astrocytomas, and glioblastomas respond in varying degrees).
Agents that commonly work in patients with high-grade gliomas include procarbazine, platinum analogs (cisplatin, carboplatin), the nitrosureas, and an oral medication called Temodar (temozolomide).
Chemotherapy agents being tested for use in recurrent glial tumors include Taxol® (paclitaxel), irinotecan, topotecan, and high-dose tamoxifen with either carboplatin or procarbazine. Other chemotherapeutic agents for the treatment of recurrent gliomas include interferon and retinoic acid.
