Irregular growth of cells in your brain causes brain cancer. It arises from primary brain cells. Primary cells are those cells, which form other brain components such as blood vessels and membranes. Not all of the brain tumors are cancerous. Malignant tumors are known as cancer. Malignant tumors can spread forcefully, overwhelming the healthy cells by taking their nutrients, space and blood.

Causes of Brain Cancer

Causes of brain cancer are unknown. According to the researchers, if they get the main cause of brain cancer, they can easily find out the preventive measures to control its occurrence. Even doctors are not able to tell what the causes of brain cancer are. It is not a hereditary or contagious illness. Even if, brain cancer can come at any age, it is the most common illness mainly in two age groups such as children and adults. Children between 3 to 12 years of age are likely to get brain cancer or adults between 40 to 70 years of age can suffer from brain cancer.

Some studies even reveal that a few kinds of brain cancers are mostly found amid the workers in industries such as rubber manufacturing, drug manufacturing and oil refining. A few other studies reveal that embalmers as well as chemists are more likely to get brain cancer.

Signs of Brain Cancer

The signs of brain cancer depend on the location, size and type of tumor. If the tumor injures a certain area or part of the brain then the signs of brain cancer can be seen. These signs can be even caused if your brain swells. The most common signs of brain tumor are nausea, changes in the personality, mood swings, problems with memory, headaches, numbness in the arms and muscle jerking.

Treatment of Brain Cancer

There are several factors such as location, size and type, which decide the treatment for brain cancer. Other factors that decide brain cancer treatment is the age and health of the patient. These methods of treatment for cancer vary for children and adults. There are three best options to treat brain cancer i.e. surgery, chemotherapy and radiation therapy.

• Surgery: It is the commonly used method of treatment for brain cancer. It is performed by a neurosurgeon that makes an opening in your skull for removing the brain cancer. Such operation is known as craniotomy. If the tumor cannot be removed completely without injuring your non-cancerous brain tissue, then the doctor removes the tumor as much as possible. In such cases, radiation therapy or chemotherapy is given to the patient to kill these remaining cancerous cells. Partial removal of the tumor will surely help the patient in getting relief from the signs by lessening the pressure on the brain.
• Chemotherapy: Brain cancer chemotherapy makes use of different drugs to remove cancer cells from your body. These drugs are given either orally or by injection into your blood vessel. Chemotherapy is generally given in cycles. Patients do not require staying in the hospital for taking the treatment. Most of the chemotherapy drugs are given to the patients in the clinic of a doctor. If the patient’s health is not so good then he or she needs to stay in the hospital for a short period of time.
• Radiation Therapy: It is also known as radiotherapy too. It involves the use of high-powered rays for injuring the DNA of the cancer cells and prevents them from growing further. It is frequently used for destroying the tumor tissue, which may not be removed with surgery. It is also used for killing the cancer cells, which remains after the surgery. This therapy is also used if surgery is not possible. In such cases, external radiations are given to the patient five days a week. These radiations are given through a big machine. The size and type of the tumor and the patient’s age decides the treatment schedule. Providing the complete dose of radiation helps in protecting the healthy tissue in the tumor area.

Above given three most useful treatments for brain cancer work effectively to remove cancer cells and treat brain cancer effectively.
