Brain Tumor and its Causes

Overview

A lump or growth of abnormal cells in your brain is known as a brain tumor. There are numerous varieties of brain tumors. Both benign (noncancerous) and malignant (cancerous) brain tumors can occur (malignant). Primary brain tumors are those that start in the brain; secondary (metastatic) brain tumors are those that start in other regions of the body and spread to the brain. A brain tumor's rate of growth can vary significantly. Your nervous system's ability to function depends on the growth pace and location of a brain tumor.

Symptoms

  • The symptoms and indicators of a brain tumor vary widely and are influenced by the size, location, and development rate of the tumor.
  • Brain tumor-related general signs and symptoms may include:
  • A headache's new onset or pattern change
  • Headaches that gradually get worse and occur more frequently
  • Vomiting or nausea without cause
  • Visual issues such as double vision, blurry vision, or reduced peripheral vision.
  • Gradual loss of feeling or motion in a leg or arm
  • Speech impediments
  • I'm terribly exhausted
  • Seizures, especially in someone who has never had seizures before

Causes

Brain tumors that begin in the brain

Primary brain tumors can develop in the brain itself or in tissues near it, such as the pituitary gland, pineal gland, cranial nerves, or the meninges, which envelop the brain. 

Primary brain tumors start when the DNA of normal cells undergoes modifications (mutations). The instructions that inform a cell what to do are encoded in its DNA. When healthy cells would perish, the mutations instruct the cells to proliferate and divide quickly and keep on surviving. A tumor is a consequence, which is a mass of aberrant cells.

Primary brain tumors in adults are significantly less frequent than secondary brain tumors, which develop when cancer travels from another part of the body to the brain.

Primary brain tumors come in many distinct varieties. Each is named for the class of cells that are involved.

  1. Gliomas: These tumors, which include astrocytomas, ependymomas, glioblastomas, oligoastrocytomas, and oligodendroglias, start in the brain or spinal cord. 
  2. Meningioma: A tumor called a meningioma develops from the membranes that cover your brain and spinal cord (meninges). Meningiomas are typically not malignant.
  3. Acoustic Neuromas (schwannomas): These benign tumors grow on the nerves that transmit hearing and balancing information from the inner ear to the brain.
  4. Pituitary Adenomas: At the base of the brain, in the pituitary gland, these tumors grow. The pituitary hormones are impacted by these tumors, and this has an impact on the entire body.
  5. Medulloblastomas: Although they can happen to anyone at any age, these malignant brain tumors tend to arise in children. A medulloblastoma typically spreads through the spinal fluid and begins in the lower back region of the brain.
  6. Germ Cell Tumors: Childhood is a time when germ cell tumors can occur where the testicles or ovaries would eventually arise. However, germ cell tumors can also impact the brain and other organs.

Treatment of Brain Tumors

Surgery is the most typical treatment for cancerous brain tumors. The objective is to eliminate as much cancer as possible without harming the brain's healthy areas. While some tumors can be safely removed due to their position, others may only be able to be removed in part due to their location. Brain cancer can benefit from even partial removal.

Brain surgery has risks, such as hemorrhage and infection. Surgery is also used to remove benign tumors that are clinically threatening. The recommended course of treatment for the original cancer type applies to metastatic brain tumors.

Chemotherapy and Radiation therapy are two examples of additional treatments that can be coupled with surgery.

You can recover from neurosurgery with the aid of physical therapy, occupational therapy, and speech therapy.
