A brain tumor
is a collection of damaged cells that multiply without control within the brain. It is also called as neoplasm, growth, mass or lesion and it is classified as either primary or secondary and can be benign or malignant.
Primary brain tumors generally develop in the brain and remain the same. Secondary brain tumors are cancers that develop anywhere in the body and spread to the brain. Malignant brain tumors grow rapidly and occupy other cells. Benign brain tumors generally do not grow rapidly but can be life threatening.
Brain Tumor Facts
Brain tumor is the leading cause of preventable or treatable blindness
American Brain Tumor Association estimates that 62,000 new cases of primary brain tumors are diagnosed in the U.S. each year.
Brain tumor is the biggest cancer killer
of children and adults under 40.
In 2013, approximately 4,300 children under the age of 20 in the US are likely to be diagnosed with primary brain tumors.
Just 14% of adults survive for five years after diagnosis. Brain tumors
reduce life expectancy by an average of 20 years, which is the highest range for any cancer.
Every day about 650 people are diagnosed with a malignant brain tumor.
Certain types of primary brain tumors most commonly occur in children, while others occur more frequently in adults.
Adult brain tumors occur typically between the ages of 40 and 60 years, and occur slightly more frequently in men.
An additional 150,000 individuals are diagnosed with metastatic brain tumors each year.
The cure rate for most brain tumors is significantly lower when compared to other types of cancer.
The worldwide cancer occurrence of a malignant brain tumor is 3.5 per 100,000 people.
In 2008, a total of 237,913 were affected by brain tumor worldwide (126,815 men and 111,098 women).
In 2002, there were 189,582 sufferers worldwide.
In United States, for every 100,000 people approximately 221 are following the diagnosis of a brain tumor and each year more than 200,000 people are diagnosed with a primary or secondary brain tumor.
Around 5,000 people died due to brain, other CNS
or intracranial tumor in 2011 in the UK, that’s more than 13 people every day.
Around 15% of malignant brain tumor patients are now likely to survive their disease for at least five years and 10% to survive for at least ten years.
Malignant brain tumor survival rates are higher for adults diagnosed at a younger age.
In the UK in 2010, around 9,150 people were diagnosed with a brain tumor, and other CNS or intracranial tumor (Males- 4,550, Females- 4,600).
More than half (57%) of brain tumors, other CNS and intracranial tumors are diagnosed in people under 65 years old.
Worldwide, an estimated 445,000 brain and other CNS tumors were diagnosed in 2008.
Almost 5,000 people lose their lives to a brain tumor every year.References:
