Brain Cancer


Description

Brain cancer is a malignant tumor that grows in the brain cells, both derived from cells of the brain itself (primary brain cancer) or from other organs that spread to the brain (secondary or metastatic brain cancer). Some types of brain cancer known among other gliomas, meningiomas, pituitary adenomas, vestibular schwannoma, and medulloblastoma.

Unlike other types of cancer, brain cancer rarely spreads to other tissues so that the classification is based only on how fast the growth of cancer cells. Stage I means the cancer cells still appear normal and slow growth, while stage IV means the cancer cells look abnormal and grow very fast.

National Cancer Institute estimates that, each year there are 22,000 new cases of brain cancer worldwide. Death rate is quite high, which is about 13,000 per year.

Cause

Secondary brain cancer is caused by the growth of cancer cells in other tissues that spread to the brain. Type of cancer that spread to most other brain between breast cancer, colon cancer, kidney cancer, lung cancer and skin cancer.

Meanwhile, primary brain cancer is caused by structural changes Deoxyribo Nucleid Acid (DNA) so that growth is not restrained. Triggers changes in the DNA is not known for sure, but suspected that many factors affect, among others, radiation, cigarette smoke and certain viral infections.

Symptom

Growth of brain cancer increased pressure inside the skull, so that often elicits feelings of pain in the head. Increasing pressure can also lead to damage to nerves and various organs in the head which raises the following symptoms.

Headache in a place or time is not usually
Headaches are more frequent or more severe intensity
Nausea and vomiting is not clear why
Penghilatan disorders, such as blurred vision or double vision
The feet and hands are often numb or hard-driven
Difficult to maintain balance
Easily confused face everyday problems
Changes in behavior or personality
Convulsions, but had no history of epilepsy
Hearing loss.

Treatment

This type of therapy for brain cancer is very diverse and can be selected based on the type and size of the cancer cell.

1. Surgery
The operation is performed for cancer which can be reached by surgery and not anywhere near sensitive parts of the brain. Risk of surgery on the brain cancer is quite high, ranging from nerve damage that can lead to sensory disturbances as well as bleeding in the brain that can lead to infection.

2. Radiation
Types of radiation are often used to treat brain cancer is the X-rays, which were fired from outside. This therapy is often done after surgery to clear the cancer cells that may remain. Side effects include triggering fatigue, headaches and scalp irritation.

3. Chemotherapy
Complaints most often when using chemotherapeutic drugs are nausea vomiting. Hair loss is also difficult to avoid because the drugs are not specific, only kill cells that are growing relatively rapidly among other cancer cells and hair cells.
