Brain tumor
A brain tumor is a development of abnormally and uncontrollably multiplying cells in the brain.
Types
According to their rate of growth and propensity to recur after therapy, brain tumors are rated.
- Low-grade tumors are those in grades 1 and 2
- High-grade tumors are those in grades 3 and 4
There are two primary categories of brain tumors:
- Non-cancerous. Low grades (grade 1 or 2) are less likely to recur following therapy because they develop more slowly.
- Cancerous. High grades (grade 3 or 4) that either originate in the brain (primary tumors) or spread there from another location (secondary tumors) are more likely to recur the following therapy.
Symptoms of brain tumors
Depending on the spot of the brain affected, you might experience different symptoms.
Typical signs include:
- Headaches
- Seizures
- Prolonged tiredness, getting sick (vomiting), and feeling constantly sick (nausea)

- Changes in mental health or behavior, such as memory issues or personality shifts
- Increasing paralysis or weakness on one side of the body
- Speech or vision issues
Sometimes you may not initially have symptoms, or they may come on very gradually.
Risk factors and causes of brain tumor
Most brain tumors have no known origin, but several risk factors could raise your likelihood of getting one.
Risk elements consist of:
- Age: Although some tumors are more common in youth, the risk of developing a brain tumor rises with age (most affect older persons between the ages of 85 and 89).
- Radiation: Only a tiny percentage of brain tumors develop by radiation exposure; some forms are more prevalent in people who have had radiotherapy, CT scans, or head X-rays.
- Heredity and genetic defects
Treatments for brain tumor
Treatments include:
- Steroids
- Medicines to treat symptoms
- Surgery
- Radiotherapy
- Chemotherapy
There is a minor risk that the tumor may come back occasionally; therefore, you might require routine follow-up consultations.
