All You Need to Know About Brain Cancer

All You Need to Know About Brain Cancer:
The formation of abnormal cells inside the brain often result in a brain tumor. Brain tumors are of two types: benign tumors and
malignant/cancerous tumors. This means that all brain tumors are not
cancerous but only the malignant type.
Malignant tumors are
further divided by primary tumors which form inside the brain and
secondary tumors which originate from elsewhere inside the body. The
latter type is also termed as brain metastasis tumors.
Risk factors
A
risk factor is anything which may increase the possibility of
developing a tumor in one’s brain. While risk factors have a part to
play in developing it, most of them do not really cause it. People with
several risk factors may never develop a brain tumor while those with
none may do.
Some of the common risk factors are:

• Age: Though brain tumors are common in older adults and children, anybody may develop them at any age.
• Gender: Males are more likely to develop brain cancer
  than females; though certain types of it, for instance meningioma, are
  common only in women.
• Exposures: The risk of developing brain tumors increases when exposed to pesticides, solvents, rubber, vinyl chloride and oil products.
• Family History: About 5% of brain tumors may occur due
  to hereditary factors, such as neurofibromatosis, tuberous sclerosis and
  Li-Fraumeni syndrome.
• Seizures and head injury: Serious head trauma often result in the development of brain tumors.

Symptoms – The symptoms of brain tumors vary
depending on the type of tumor and its size, location and growth rate.
The usual symptoms include:

• Severe headaches
• Seizures
• Vomiting
• Weakness
• Nausea
• Sensory changes
• Memory changes
• Vision changes
• Difficulty in sleeping

DiagnosisDoctors follow a lot of test
procedures to diagnose a brain tumor and its type. They also do tests to
identify whether or not the tumor has spread to a different part of the
body, which is known as metastasis.
The following things are considered by doctors to decide on the type of the diagnostic test:

• The patient’s signs and symptoms
• The patient’s age and health condition
• The type of the tumor suspected

Doctors do different types of tests depending on the aforementioned factors. Some of these include:

• MRI (Magnetic Resonance Imaging): It is used to have a
  detailed image of the body and measure the size of the tumor. If a tumor
  is detected, tissue of the tumor is collected through surgery or biopsy
  in order to identify its type.
• CT scan: Unlike MRI which uses magnetic field, CT scan
  provides a 3D picture of the body through X-rays. It helps identify
  bleeding inside the brain and changes to bone inside the skull.
• Lumbar puncture: In this procedure, doctors take a
  sample of CSF (cerebrospinal fluid) through a needle to identify tumor
  cells or biomarkers. Biomarkers are substances present in the urine,
  spinal fluid, or other fluids of people with a certain type of cancer.
• Vision, neurological and hearing tests: These test are done to determine whether or not the tumor is affecting the functioning of the brain.

TreatmentUpon diagnosing a brain tumor, a
medical team is formed to determine the possible treatment options.
There are some treatment options available to get rid of it, including:

• Surgery: It involves resecting the tumor either partially or completely
• Chemotherapy: Drugs are administered here to do away with tumor cells, though they may result in side effects
• Radiotherapy: This is the most usual treatment option where the tumor is destroyed with gamma rays or x-rays

Finally, brain cancer should be treated immediately upon the diagnosis
in order to avoid any long-term physical disabilities and even death.
