percentage of study population developing pituitary tumors that invade the glandular capsule during a period of time 
percentage of study population developing pituitary tumors that replace a portion of the gland during a period of time 
The number of individuals in a study population which develop new instances of pituitary gland tumors in which the neoplastic tissue only partially eliminates and takes the place of the normal tissue in the pituitary gland, resulting in a mix of neoplastic and normal tissues, during a specified period of time divided by the total number of individuals in the study population, expressed as a percentage. A tumor is an abnormal growth of tissue resulting from uncontrolled, progressive multiplication of cells and serving no physiological function. The pituitary gland is a small, oval endocrine gland attached to the base of the vertebrate brain and consisting of an anterior and posterior lobe, the secretions of which control the other endocrine glands and influence growth, metabolism, and maturation.
percentage of study population developing pituitary tumors that replace the entire gland during a period of time
