Brain Tumor – Sypmtons and Causes

- January 29, 2020

INTRODUCTION

A woman whose psychosis was dismissed as bipolar disorder later discovered she has a tennis-ball sized tumor in her brain. Laura Skerritt, 22, from Templecombe in Somerset – began suffering migraines, sickness and psychosis in 2016. The swimming instructor went to her GP, who put the symptoms down to anxiety or depression. After being prescribed anti-depressants, Miss Skerritt deteriorated, with her struggling to walk and enduring seizures by November 2018.
A scan eventually revealed a central neurocytoma tumor, which required immediate surgery to prevent her suffering a life-threatening stroke.
Just over a year later, it has grown, with her having to go under the knife yet again.

OVERVIEW
WHAT IS BRAIN TUMOR?
A brain tumor is a mass or growth of abnormal cells in your brain.
Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant). Brain tumors can begin in your brain (primary brain tumors), or cancer can begin in other parts of your body and spread to your brain (secondary, or metastatic brain tumors).
How quickly a brain tumor grows can vary greatly. The growth rate as well as location of a brain tumor determines how it will affect the function of your body system.
Brain tumor treatment options depend on the type of brain tumor you have, as well as its size and location.
WHAT ARE THE SYMPTOMS?
The signs and symptoms of a brain tumor vary greatly and depend on the brain tumor’s size, location and rate of growth.

General signs and symptoms caused by brain tumors may include:
• New onset or change in pattern of headaches
• Headaches that gradually become more frequent and more severe
• Unexplained nausea or vomiting
• Vision problems, such as blurred vision, double vision or loss of peripheral vision
• Gradual loss of sensation or movement in an arm or a leg
• Difficulty with balance
• Speech difficulties
• Confusion in everyday matters
• Personality or behavior changes
• Seizures, especially in someone who doesn’t have a history of seizures
• Hearing problems
WHEN SHOULD YOU SEE A DOCTOR?
Make an appointment with your doctor if you have persistent signs and symptoms that concern you.

CAUSES
BRAIN TUMORS THAT BEGIN IN THE BRAIN
Acoustic neuroma (schwannoma)
Primary brain tumors originate in the brain itself or in tissues close to it, such as in the brain-covering membranes (meninges), cranial nerves, pituitary gland or pineal gland.
Primary brain tumors begin when normal cells acquire errors (mutations) in their DNA. These mutations allow cells to grow and divide at increased rates and to continue living when healthy cells would die. The result is a mass of abnormal cells, which forms a tumor.
In adults, primary brain tumors are much less common than are secondary brain tumors, in which cancer begins elsewhere and spreads to the brain.
Many different types of primary brain tumors exist. Each gets its name from the type of cells involved. Examples include:
• Gliomas. These tumors begin in the brain or spinal cord and are among the most common tumours.
• Meningiomas. A meningioma is a tumor that arises from the membranes that surround your brain and spinal cord (meninges). Most meningiomas are noncancerous.
• Acoustic neuromas (schwannomas). These are benign tumors that develop on the nerves that control balance and hearing leading from your inner ear to your brain.
• Pituitary adenomas. These are mostly benign tumors that develop in the pituitary gland at the base of the brain.
• Medulloblastomas. These are the most common cancerous brain tumors in children. A medulloblastoma starts in the lower back part of the brain and tends to spread through the spinal fluid.
• Germ cell tumors. Germ cell tumors may develop during childhood where the testicles or ovaries will form. But sometimes germ cell tumors affect other parts of the body, such as the brain.
• Craniopharyngiomas. These rare, noncancerous tumors start near the brain’s pituitary gland, which secretes hormones that control many body functions. As the craniopharyngioma slowly grows, it can affect the pituitary gland and other structures near the brain.

CANCER THAT BEGINS ELSEWHERE AND SPREADS TO THE BRAIN
Secondary (metastatic) brain tumors are tumors that result from cancer that starts elsewhere in your body and then spreads (metastasizes) to your brain.
Secondary brain tumors most often occur in people who are suffering from one type of Cancer or the other in other parts of the body.
These are more common in adults than the primary brain tumors.

Virtually any Cancer can spread to the brain, but common types include:
• Breast cancer
• Colon cancer
• Kidney cancer
• Lung cancer
• Melanoma

RISK FACTORS
In most people with primary brain tumors, the cause is not often clear. But the following factors may increase the risk of a brain tumor.

Risk factors include:
• Exposure to radiation. People who have been exposed to a type of radiation called ionizing radiation have an increased risk of brain tumor. Examples of ionizing radiation include radiation therapy used to treat cancer and radiation exposure caused by atomic bombs.
• Family history of brain tumors. A small portion of brain tumors occurs in people with a family history of brain tumors or a family history of genetic syndromes that increase the risk of brain tumors.
