Welcome, it’s really thoughtful of you to want to read this article. Brain tumor are now becoming more frequent than usual, it is indeed advisable to educate yourself on the causes and consequences of this life threatening ailment.
A brain tumor is an anthology, or mass of abnormal cells in your brain. Your skull, which encloses your brain, is very rigid; any growth inside such a restricted space can cause serious problems.
Simply put, a brain tumor is a growth of abnormal cells in your brain.
Of course many different types of brain tumors exist. Some brain tumors are noncancerous, while others are cancerous that is 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).
There are various types and they include;
- Acoustic neuroma
- Pituitary tumors
- Embryonal tumors
- Pineoblastoma and a whole lot more.
Symptoms of brain tumor
The signs and symptoms of a brain tumor vary greatly and depend on the brain tumor’s size, where it is found and the rate at which it grows. Broad-spectrum signs and symptoms caused by brain tumors may include:
- Headaches that slowly becomes more frequent & more severe overtime.
- Issues with vision; such as blurred or double vision, or loss of peripheral vision
- Unexplained nausea or vomiting
- Gradual loss of sensation or
- Locomotion in the arm or legs
- Confusion in everyday matters
- Personality or behavioral changes
- Seizures; especially in an individual who doesn’t have any history of seizures.
- Hearing difficulties and a whole lot more.
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.
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. These tumors are less common in adults, but they do occur.
Pituitary adenomas:These are mostly benign tumors that develop in the pituitary gland at the base of the brain. These tumors can affect the pituitary hormones with effects throughout the body.
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 have a history of cancer. But in rare cases, a metastatic brain tumor may be the first sign of cancer that began elsewhere in your body.
In adults, secondary brain tumors are far more common than are primary brain tumors.
Any cancer can spread to the brain, but common types include:
- Breast cancer
- Colon cancer
- Kidney cancer
- Lung cancer
- Risk factors
In most people with primary brain tumors, the cause of the tumor is not clear. But doctors have identified some factors that may increase your risk of a brain tumor.
Risk factors include:
Exposure to radiation. People who have been exposed to a certain type of radiation called ionizing radiation have an increased risk of brain tumor prevalence. Examples of ionizing radiation; are 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 genetic syndromes that in turn increases the risk of brain tumors.
