A brain tumor is a mass or growth of abnormal cells in the brain. Many various types of brain tumors exist. Some brain tumors are noncancerous, and some brain tumors are cancerous. Brain tumors can start in the brain, or cancer can start in other parts of the body and expand to the brain. How rapidly a brain tumor grows can differ significantly. The growth rate and location of a brain tumor understand how brain tumors will influence the function of the nervous system. Brain tumor treatment choices depend on the type of brain tumor you have, and its size and location.
Symptoms of Brain Tumor
The signs and symptoms of brain tumors differ significantly and depend on the brain tumor’s size, location, and rate of growth. General signs and symptoms of brain tumors may involve:
1) New onset or change in the pattern of headaches
2) Headaches that gradually become more frequent and more serious
3) Not explained nausea or vomiting problem
4) Vision problems, like blurred vision, double vision or loss of peripheral vision
5) The gradual loss of sensation or movement in an arm or a leg
6) Difficulty with balance
7) Speech complexities
8) Confusion in daily matters
9) Personality or behavior changes
10) Seizures, mainly in someone who does not have a history of seizures
11) Hearing difficulties
Brain Tumor Causes
Primary brain tumors produce in the brain itself or in tissues close to it, like in the brain-covering membranes, cranial nerves, pituitary gland or pineal gland. Primary brain tumors cause when healthy cells to acquire errors in their DNA. These mutations permit cells to grow and divide at enhanced rates and to continue living when healthy cells would die. The result is a mass of abnormal cells, which form a tumor.
In adults, primary brain tumors causes are much less common than are secondary brain tumors, in which cancer starts elsewhere and expands to the brain. Secondary brain tumors are tumors that result from cancer that begins elsewhere in the body and then extends to the brain. Secondary brain tumors most often happen in people who have a history of cancer disease. But in rare cases, a metastatic brain tumor may be the first sign of cancer that started elsewhere in the body. In adults, secondary brain tumors are far more popular than are primary brain tumors. Any cancer can expand to the brain, but common types include:
Diagnosis of Brain Tumor
If it is suspected that you have a brain tumor, the doctor may suggest many tests and procedures for the diagnosis of the brain tumor, including:
1) Neurological test
2) Imaging test
3) Check to find cancer in other parts of the body
4) Biopsy test
Treatment of Brain Tumor
Treatment of brain tumors depends on the type, size and location of the tumor, and the overall health and the choices.
1) Surgery: If the brain tumor is positioned in a place that makes it possible for an operation, the surgeon will work to eliminate as much of the brain tumor as possible. In some cases, tumors are small and easy to separate from surrounding brain tissue, which makes full surgical removal possible. In other cases, tumors can not be separated from surrounding tissue, or they are positioned near sensitive areas in the brain, making surgery risky. In these situations, the doctor eliminates as much of the tumor as is safe. Even removing a portion of the brain tumor may assist in minimizing the signs and symptoms. Surgery to eliminate a brain tumor carries risks, like infection and bleeding. Other changes may depend on the part of the brain where the tumor is positioned. For instance, surgery on a tumor near nerves that link to the eyes may indicate a chance of vision loss.
2) Radiation therapy
3) Radiosurgery: Stereotactic radiosurgery is not a form of surgery in the traditional sense. Instead, radiosurgery applies multiple beams of radiation to provide a highly focused form of radiation treatment to destroy the tumor cells in a tiny area. Each beam of radiation is not especially powerful, but the point where all the beams meet at the brain tumor gets a massive dose of radiation to destroy the tumor cells. There are different types of technology used in radiosurgery to deliver radiation for treating brain tumors, like a Gamma Knife or linear accelerator. Radiosurgery is typically performed in one treatment, and in most cases, you can go home the same day.
5) Drug therapy
