What Is a Brain Tumor?
A tumor is a mass of tissue that is formed by the accumulation of abnormal cells. Normally, the cells grow old or get damaged, they die, and new cells take their place. Tumor cells will grow even though the body does not need them, and unlike normal old cells, they don’t die. As this process goes on, the tumor continues to grow as more and more cells are added to the mass.
Primary brain tumors may emerge from various cells that make up the brain and the central nervous system are named for the kind of cell in which they form in the first. The common types of adult brain tumors are gliomas as in astrocytic tumors. These tumors might form from astrocytes and also the other types of glial cells, which helps the cells to keep nerves healthy.
Types of Brain Tumors
A benign tumor is not a cancerous tumor. Unlike cancer tumors, noncancerous tumors are unable to spread throughout the body. A nonmalignant tumor gets serious, they are to be pressed on the primary nerve, the main artery, or compresses brain matter. Benign tumors will respond well to the treatment and the prognosis is usually favorable.Most Common Types of Benign Tumors
- Adenomas (epithelial tissue that covers the organs and glands)
- Meningiomas (brain and spinal cord)
- Fibromas or fibroids (connective tissue of any organ – most commonly found in the uterus)
- Papillomas (skin, breast, cervix, and mucus membranes)
- Lipomas (fat cells)
- Nevi (moles)
- Myomas (muscle tissue)
- Hemangiomas (blood vessels and skin)
- Neuromas (nerves)
- Osteochondromas (bones)
It Depends on the location and size of a benign tumor, treatment might not be necessary. Then the doctors will monitor it, and track the patient’s symptoms, and do tests at specific intervals. Benign tumors are surrounded by a protective “sac” mechanism performed by the immune system that segregates them from the rest of the body and enables them to be easily removed.
Malignant tumors are formed in abnormal cells that are highly unstable and also they travel through the bloodstream, circulatory system, and lymphatic system. Malignant cells don’t have the chemical adhesion molecules to anchor them to the original growth site that benign tumors possess. Many of the suspected causes of cancer are widely accepted by the medical community while others are not. Obesity, smoking, alcohol consumption, poor diet, environmental pollution, heavy metal exposure, and household toxins are some of the culprits that might lead to cancer in the body.Most Common Types of Malignant Tumors
- Sarcomas (connective tissues such as muscle, tendon, fat, and cartilage)
- Carcinomas (organs and gland tissue such as the breast, cervix, prostate, lung, and thyroid)
Malignant tumors might not have the symptoms initially but at the first indication it has something that not be right or it may be the detection of a painless lump. These types of tumors are “elastic,” which will enable them to grow fairly large before they are detected. If they grow and begin to press against the organs, blood vessels, and nerves, pain and general soreness at the site may occur.
Precancerous tumors fall between benign and malignant. These types of growths may have the markers that to be malignant but they are not yet apparent. These are not to be characterized as malignant unless irrepressible cell growth ensues.
Brain Tumor Preventions
The more you know about prevention, the better you can guard against all tumor growth in the body. Boosting the body’s immune system through diet, exercise and healthy lifestyle choices are of defense.
