Brain tumor could be defined as either malignant or benign. They could occur at any age and the exact cause of brain tumor is not at all clear. The symptoms of the brain tumor depend upon their size type and location.

Classification The adenomas can be divided into 2 categories based on size:

Microadenomas include tumors which are less than 10 mm. These tumors are small and rarely damage the rest of the pituitary or nearby tissues. There are many individuals who have small adenomas that are never detected because they never grow large enough or secrete enough hormones to cause a problem.

Macroadenomas are tumors which is more than 10mm across or larger. They can affect a person’s health in 2 ways. The first symptoms is when they make too much of a certain hormone. The second symptoms is by pressing on normal parts of the pituitary or on nearby nerves, such as the optic nerve

Symptoms

Some of the signs and symptoms of a pituitary tumor, including:

  • Extra hormones in the blood
  • Flushing of the face
  • Weak muscles and bones
  • High blood pressure
  • Irregular heartbeat
  • Headache
  • Vision loss

Treatment

The treatment for malignant and benign pituitary tumors depends upon the size of the tumor. The neurosurgeon must try to determine whether the tumor is micro adenoma or macro adenoma. The other aspect which needs to be checked includes whether the adenomas produce hormones or has spread to other sites.
