context_page_description: Phyllodes tumors, also cystosarcoma phyllodes, cystosarcoma phylloides and phylloides tumor, are typically large, fast-growing masses that form from the periductal stromal cells of the breast. They account for less than 1% of all breast neoplasms.
context_section_description: This is predominantly a tumor of adult women, with very few examples reported in adolescents. 
  Patients typically present with a firm, palpable mass.  These tumors are very fast-growing, and can increase in size in just a few weeks.  Occurrence is most common between the ages of 40 and 50, prior to menopause. This is about 15 years older than the typical age of patients with fibroadenoma, a condition with which phyllodes tumors may be confused. They have been documented to occur at any age above 12 years.
