All You Need to Know About Brain Cancer

The formation of abnormal cells in the brain often results in a brain tumor. Brain tumors are of two types: benign and malignant tumors / cancers. This means that not all brain tumors are cancerous, but only the malignant type.
Malignant tumors are further divided by primary tumors that form in the brain and secondary tumors that originate from other parts of the body. The latter type is also called tumors of cerebral metastases.
Risk factors
A risk factor is anything that can increase the risk of developing a tumor in his brain. Although risk factors have a role to play in development, most of them do not cause. People with multiple risk factors can never develop a brain tumor while those who can not do so.
Some common risk factors are:

    Age: Although brain tumors are common in the elderly and children, everyone can develop at any age.
    Sex: Men are more likely to develop brain cancer than women; Although some types of it, such as meningioma, are common only in women.
    Risks: The risk of developing brain tumors increases when exposed to pesticides, solvents, rubber, vinyl chloride and petroleum products.
    Family history: About 5% of brain tumors can occur due to hereditary factors, such as neurofibromatosis, tuberous sclerosis and Li-Fraumeni syndrome.
    Convulsions and head injuries: Traumatic brain injury often results in the development of brain tumors.
symptoms
Symptoms of brain tumors vary depending on the type of tumor and its size, location and growth rate. Usual symptoms include:

    Severe headache
    convulsions
    puke
    weakness
    nausea
    Sensory changes
    Memory changes
    Changes in Vision
    Difficulty sleeping
diagnostic
Doctors are still a lot of test procedures to diagnose a brain tumor and its type. In addition, they test to determine if the tumor is extended to another part of the body, which is known as metastasis.
The following things are considered by doctors to decide the type of diagnostic test:

    Patient signs and symptoms
    Age and health of the patient
    The type of tumor suspected
Doctors do different types of tests depending on the above factors. Some of them include:

    MRI (Magnetic Resonance Imaging): Allows to have a detailed image of the body and measure the size of the tumor. If a tumor is detected, the tumor tissue is collected by surgery or a biopsy to identify its type.
    CT: Unlike MRI uses a magnetic field, computer tomography provides a 3D image of the body by X-rays to identify bleeding in the brain and changes in the bone inside the skull.
    Lumbar puncture: In this procedure, doctors take a sample of CSF (cerebrospinal fluid) through a needle to identify biomarkers or tumor cells. Biomarkers are substances in the urine of cerebrospinal fluid or other fluids of people with certain types of cancer.
    Vision, Neurological and Hearing Tests: These tests are performed to determine whether the tumor affects the functioning of the brain or not.
treatment
When diagnosing a brain tumor, a medical team is trained to determine the possible treatment options. There are a few treatment options available to get rid of it, including:

    Surgery involves partial or total resection of the tumor
    Chemotherapy drugs are administered here to kill tumor cells, but can cause side effects
    Radiation therapy: This is the most common treatment option where the tumor is destroyed by gamma rays or X-rays
Finally, brain cancer should be treated immediately after diagnosis to avoid long-term physical disability and even death.
