Types of gliomas tend to be the most common brain tumors, according to the Cancer Research UK. For instance, low-grade astrocytomas are common among men and women between the ages of the 20s and 50s, according to the National Brain Tumor Society. Anaplastic astrocytomas are more common in men, but they can also be found in women. These tumors affect people between the ages of 30 and 50.
According to Mayfield Clinic, brain tumors can be found in certain lobes of the brain, such as the frontal lobe, parietal lobe, occipital lobe, brain stem or temporal lobe. The pituitary gland can also be affected. Each area can cause different symptoms. For instance, tumors affecting the occipital lobe could cause a loss of vision, and tumors in the frontal lobe can cause emotional changes, paralysis on one side of the body or vision loss.Learn more about Cancer
