symptoms that appear before brain cancer/tumours
Brain Cancer Symptoms , Cause , Signs And Prevention : Brain cancers include primary brain tumours, which start in the brain and almost never spread to other parts of the body, and secondary tumours (or metastases), which are caused by cancers that began in another part of the body.
Brain tumor is a growth of cells in the brain or near it. Brain tumors can happen in the brain tissue. Brain tumors also can happen near the brain tissue. Nearby locations include nerves, the pituitary gland, the pineal gland, and the membranes that cover the surface of the brain.
Brain tumors can begin in the brain. These are called primary brain tumors. Sometimes, cancer spreads to the brain from other parts of the body. These tumors are secondary brain tumors, also called metastatic brain tumors.
There are more than 40 major types of brain tumours, which are grouped into two main types:
• benign – slow-growing and unlikely to spread. Common types are meningiomas, neuromas, pituitary tumours and craniopharyngiomas.
• malignant – cancerous and able to spread into other parts of the brain or spinal cord. Common types include astrocytomas, oligodendrogliomas, glioblastomas and mixed gliomas.

Symptoms
The signs and symptoms of a brain tumor depend on the brain tumor’s size and location. Symptoms also might depend on how fast the brain tumor is growing, which is also called the tumor grade.
General signs and symptoms caused by brain tumors may include:
• Headache or pressure in the head that is worse in the morning.
• Headaches that happen more often and seem more severe.
• Headaches that are sometimes described as tension headaches or migraines.
• Nausea or vomiting.
• Eye problems, such as blurry vision, seeing double or losing sight on the sides of your vision.
• Losing feeling or movement in an arm or a leg.
• Trouble with balance.
• Speech problems.
• Feeling very tired.
• Confusion in everyday matters.
• Memory problems.
• Having trouble following simple commands.
• Personality or behavior changes.
• Seizures, especially if there is no history of seizures.
• Hearing problems.
• Dizziness or a sense that the world is spinning, also called vertigo.
• Feeling very hungry and gaining weight.
• sleep problem

Causes :
Brain tumors that begin in the brain :-
Brain tumors that start as a growth of cells in the brain are called primary brain tumors. They might start right in the brain or in the tissue nearby. Nearby tissue might include the membranes that cover the brain, called meninges. Brain tumors also can happen in nerves, the pituitary gland and the pineal gland.
Brain tumors happen when cells in or near the brain get changes in their DNA. A cell’s DNA holds the instructions that tell the cell what to do. The changes tell the cells to grow quickly and continue living when healthy cells would die as part of their natural life cycle. This makes a lot of extra cells in the brain. The cells can form a growth called a tumor.
It’s not clear what causes the DNA changes that lead to brain tumors. For many people with brain tumors, the cause is never known. Sometimes parents pass DNA changes to their children. The changes can increase the risk of having a brain tumor. These hereditary brain tumors are rare. If you have a family history of brain tumors, talk about it with your health care provider. You might consider meeting with a health care provider trained in genetics to understand whether your family history increases your risk of having a brain tumor.
When brain tumors happen in children, they’re likely to be primary brain tumors. In adults, brain tumors are more likely to be cancer that started somewhere else and spread to the brain.
Prevention
There’s no way to prevent brain tumors. If you get a brain tumor, you didn’t do anything to cause it. People with an increased risk of brain tumor might consider screening tests. Screening isn’t brain tumor prevention. But screening might help find a brain tumor when it’s small and treatment is more likely to be successful.
