What are Tumors?
Patients suffering from conditions within the skull, like brain tumors, need a craniotomy.
A tumor is an abnormal growth that occurs due to uncontrolled cell multiplication. In the skull, tumors can cause pressure on the brain because of the fixed size of the skull.
Tumors can be classified by their origin. Primary tumors are those located at the site where the tumor began to grow or where it originated. Metastatic, or secondary, tumors are those that have spread to other parts of body from the original tumor site.
Tumors are also classified based on their tendency to grow. Malignant, or cancerous, tumors tend to keep growing despite treatment and can become life threatening. Benign, or non-cancerous, tumors tend to grow more slowly and can be cured by treatment. However, benign tumors can still cause problems because of the pressure they cause on the surrounding brain tissue. In some cases, benign tumors can be life threatening.
