Brain Tumour could be a cancerous or none cancerous growth of abnormal cells in the brain
Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (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 as secondary (metastatic) brain tumors.
The signs and symptoms of a brain tumor vary greatly and depend on the brain tumor’s size, location and rate of growth.
General signs and symptoms caused by brain tumors may include:
1. New onset or change in pattern of headaches
2. Headaches that gradually become more frequent and more severe
3. Unexplained nausea or vomiting
4. Vision problems, such as blurred vision, double vision or loss of peripheral vision
5. Gradual loss of sensation or movement in an arm or a leg
6. Difficulty with balance
7. Speech difficulties
8. Difficulty making decisions
9. Inability to follow simple commands
9. Personality or behavior changes
10. Seizures, especially in someone who doesn’t have a history of seizures
Primary brain tumors originate in the brain itself or in tissues close to it, such as in the brain-covering membranes
Primary brain tumors begin when normal cells develop changes (mutations) in their DNA. A cell’s DNA contains the instructions that tell a cell what to do. The mutations tell the cells to grow and divide rapidly and to continue living when healthy cells would die. The result is a mass of abnormal cells, which forms a tumor.
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. Rarely, 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:
Diagnosis of a brain tumor begins with a physical exam and a look at your medical history.
The physical exam includes a very detailed neurological examination. Your doctor will conduct a test to see if your cranial nerves are intact. These are the nerves that originate in your brain.
The treatment of a brain tumor depends on:
the type of tumor
the size of the tumor
the location of the tumor
your general health
The most common treatment for malignant brain tumors is surgery. The goal is to remove as much of the cancer as possible without causing damage to the healthy parts of the brain.
While the location of some tumors allows for safe removal, other tumors may be located in an area that limits how much of the tumor can be removed. Even partial removal of brain cancer can be beneficial.
