Primary Tumor

A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass.

Famous quotes containing the word primary:

    One of the effects of a safe and civilised life is an immense oversensitiveness which makes all the primary emotions somewhat disgusting. Generosity is as painful as meanness, gratitude as hateful as ingratitude.
    George Orwell (1903–1950)
