Common brain tumor symptoms tend to be non-specific, mimicking other
illnesses. Many times, symptoms don't immediately raise red flags that
scream "brain tumor"
to a physician. Brain tumors are rare, despite their increasing rate of
diagnosis and because of this rarity, physicians often don't evaluate
patients right off the bat for brain tumors. They may rule out other,
less serious conditions initially.
Brain tumor symptoms vary greatly from person to person because of two factors: where the tumor is located and its size. The size of a tumor, however, does not effect severity of symptoms. A very small tumor can cause severe symptoms. It is all relative to what part of the brain is affected.
