What is a tumor?
The word tumor is a broad term to identify any growth within the body but has become synonymous with a benign or malignant growth. At times the word neoplasm is used which is essentially a new growth of tissue that has no purpose or function in the body.
A tumor arises from uncontrolled or an abnormal growth of cells that has no physiological function in the body, occupies space or destroys surrounding tissue to fit in the specific area and can affect the function or health of the organ it affects.
Tumors should not be confused with other growth phenomenon in the body like hyperplasia or hypertrophy. These terms are used when an organ enlarges or when there is an increase in the organ’s cells or layers of tissue than would be considered the norm leading to an increase in size of the affected organ. This enlargement is not a tumor.
