Brain cancer is a type of cancer in which malignant tissues arise in the brain and develop a tumor. This results into an abnormal growth of cells. Later, these cells start spreading to other parts of the body. So these parts start getting affected. A person suffering from brain tumor can suffer from various other problems like memory loss, weight loss, and appetite loss as the immune system gets weakened and body becomes incapable of fighting against the viruses that attack from outside. Surgery is the only option which works best on this cancer and is highly recommended for its treatment. According to a study conducted by National Cancer Institute, nearly 220,000 people are diagnosed of this cancer out of which 13000 deaths are reported. Tissues which cause brain tumor include ependymomas, astrocytomas, oligodendrogliomas and choroid plexus papillomas. Brain cancer surgery aims at removing the tumor and restricting the spread of the malignant cells. The smaller the cancerous tissue the easier it is to perform the surgery and cure it.
Brain Cancer Surgery
Brain cancer surgery is widely used treatment as it helps to remove the tumor and the malignant cells that spread throughout the body. It is performed only after diagnosing the tumor, the size and detecting the spread of malignant tissues. It also gives them an idea whether the tissue can be removed permanently or not.
Different types of surgery of brain cancer are:-
Biopsy is a type of surgery done to remove the tumor caused due to brain cancer. In biopsy, a hole is made in the skull and a thin needle is inserted inside. With the help of this needle, a small piece of the tumor is removed and sent to the laboratory for infection. This surgery is a part of the diagnosis and it helps to identify the size of tumor, its type and the kind of treatment required to remove this tumor.
Craniotomy is a part of brain cancer surgery in which an area of bone in your skull is cut and the brain is operated. In this operation, the tumor is operated upon and removed along with the malignant cells. Later, the area which has been cut is stitched back. In this surgery it is very important to remove all the malignant cells that have spread throughout the body. Even if one cell is left there is a chance of tumor re-developing in the same area. As this surgery is risky it is rarely performed by the surgeons.
A brain cancer research conducted by World Cancer Research Fund American Institute for Cancer Research shows that there are 30 percent chances of tumor re- occurring even after performing craniotomy.
In this surgery, a highly powered microscope is used to analyze and examine the brain tissue. This microscope helps the surgeon to have a closer look at the tissue and to decide which part of the tumor should be removed. Microsurgery also includes several other techniques like CUSA and Neuro Navigation which help to remove the tumor completely without damaging the structures near other parts of the brain. Before performing this surgery, various other tests like cardiac monitoring and CSF are performed.
In this surgery, a hole which is smaller than a dime is made in the skull and a surgical microscope is inserted. This microscope helps to develop high resolution pictures which help the surgeon to determine the spread of malignant cells in the areas of skull, spine and brain. After this, a laser surgery or cyst surgery is performed to kill the malignant cells and the tumor.
Thus, the above article describes the types of brain cancer surgeries such as biopsy, craniotomy, microsurgery and neuroendoscopy which are performed for removing the cancer cells from the body. Among all these surgeries, microsurgery and neuroendoscopy are highly recommended for treating brain cancer.
