Cancer usually develops when the body’s natural growth function or mechanism stops working in a normal way. In other words normal growth of cells is obstructed. Old cells instead of dying start growing abnormally and produce new abnormal cells.
A number of cancer forms are there which are usually curable too such as breast cancer, prostate cancer, testicular cancer etc. but there are others forms as well which are fatal and life threatening.
In this particular article we are going to throw light on basic information about brain cancer. Brain cancer is one of the deadliest cancers and the rate of survival of the victims is too low in most cases.
What is brain cancer?
When cancer starts somewhere else in the body and spreads in the brain it causes brain cancer. Brain cancer also known as brain tumors results from cancer in some other body parts.
When normal cell growth is stopped, old cells grow at a high increased level which finally appear in the form of massive abnormal and unhealthy cells. These abnormal cells form tumors.
How brain cancer affects central nervous system?
It usually depends on the complexity and place of the tumor or cancer in the brain and how it affects your central nervous system.
If a brain tumor begins in the brain originally it is called primary brain tumor. When cancer begins in other body parts and spreads in the brain it is termed as secondary brain tumor.
Types of brain cancer:
When it comes to the National Brain Tumor Society there are several types of brain cancer, maybe 200 or more.
Basically brain tumors begin developing in the brain and most of them are fast growing. There are many other kinds too which may be benign. Most of the brain tumors are cancerous and they may damage brain tissues badly which decreases the quality of your life.
Following are some common types of brain cancer:
- Astrocytomas (the most common type of brain cancer that develops anywhere in the brain or maybe in the spinal cord).
- Glioblastoma multiforme (another common brain cancer that is aggressive and fast growing. It may appear on lobe but mostly it develops in temporal lobes).
- Meningioma (this form appears in cell membranes that invade the brain and spinal cord. It’s usually curable or removable through surgery).
Symptoms usually depend on which part of the brain tumor or cancer is. When cancer or tumor is near the optic nerve system, sight or vision problems may appear.
Cancer or tumor in front of the brain causes lack of concentration. Cancer located in any other part of brain may cause:
- Difficulty speaking
- Lack of concentration
- Decreased mobility
- Paralyzed body or some part of body.
- Memory loss
Common or early symptoms/signs may include:
- Severe headache
- Muscle ache/weak muscles
Treatment for brain cancer is available however risk factor is always there. Brain cancer can be treated through:
- Radiation therapy
Surgery is usually opted when cancer or tumor can be easily removed and if cancer is visible even after surgery radiation therapy is used to remove remaining cancer/tumor. Chemotherapy is mostly followed by chemotherapy.
