A brain tumor is an abnormal brain cell mass or development. There are numerous different brain tumors. Some brain tumors (benign) are not cancerous and some brain tumors (malignant). Brain tumors can start in the brain or can start to spread to the brain (secondary, or metastatic, brain tumors) in other areas of the body. Cancer is also known to start and breastfeed. The rate of growth of a brain tumor can be very different. The growth rate and location of the brain tumor determine how the nervous system affects its function. The options for brain tumor treatment depend on the type and size of the brain tumor of the patient.
Tumors in the brain are classified depending on the rate and the likelihood of their growth after treatment. Tumors of grades 1 and 2 are of low grade and of grade 3 and grade 4 are of high grade.
Two main brain tumor types exist:
Brain tumors that are non-cancerous are low (grade 1 or 2) and are thus less likely to grow slowly and return once they are treated.
Cancer (malignant) tumors of the brain ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ are high-grade tumors of the brain (grades 3 or 4) and either begin or spread to the brain from other places (secondary tumors); they are more likely to grow back after treatment
Primary tumors of the brain originate in or in close to the brain tissues, such as the membranes (meninges) in the brain, cranial nerves, hypophyseal gland, or pineal gland. When normal cells acquire errors (mutations) in their DNA, primary brain tumors start. These mutations allow cells to increase and divide and continue to live when healthy cells die. The consequence is a tumor-forming mass of abnormal cells. Primary brain tumors are far less common in adults than secondary brain tumors, where cancer starts elsewhere and spreads to the brain
Surgery consists of the removal during an operation of the tumor and some healthy surrounding tissue. The first treatment for a brain tumor is usually used. This is often a low-grade brain tumor that needs only treatment. Tumor removal may improve neurological symptoms, demagnetization, and genetically engineered analysis of the tissues, help improve the efficiency of other brain tumor therapies, and often improve a brain tumorÃ¢â‚¬â„¢s prognosis.
A neurosurgeon at B.P Poddar is a physician who specializes in brain and vertebrae surgery. Brain surgery requires removing a part of the skull known as a craniotomy. The patientÃ¢â‚¬â„¢s own bone is used to cover the opening in the skull once the surgeon removes the tumor. Rapid progress has been made in brain tumor surgery, including cortical mapping, enhanced imaging, and fluorescent dyes.
Antibiotics can be prescribed to help reduce swelling around the tumor after a diagnosis with a brain tumor.
Other medications may be used to help with other brain tumor symptoms, such as seizure anti-epileptic medicines and headaches painkillers. Often surgery is used to remove tumors of the brain. It is intended to remove as safely as possible the abnormal tissue. It is not always possible to remove a tumor, so any abnormal cells that are left behind can require further treatment with radiation or chemotherapy. Non-cancer therapy is often effective and it can be fully recovered. Sometimes the tumor may return a small chance, so regular monitoring is recommended.
