Final answer:
The statement is false; a cystadenoma is a fluid or mucus-filled ovarian tumor, not blood-filled. It is distinct from hematoma or hemangioma which involve blood. Other medical conditions described include prostate cancer prevalence in elderly males, menarche, menstrual cycle phases, and the buffy coat composition in blood.
Step-by-step explanation:
False: A cystadenoma is not a glandular tumor filled with blood; it typically contains fluid or mucus. Cystadenomas are a type of ovarian tumor that arises from the glandular tissue of the ovary and is characterized by the presence of cystic spaces. These are usually filled with a watery or mucinous substance, not with blood. They can be benign or malignant and may vary in size.
When examining other medical conditions, it's notable that a majority of American males by the age of 80 do have some cancerous or pre-cancerous cells in their prostate gland. Menarche is the beginning of menstruation in adolescent females, marking the onset of reproductive capability. Moreover, during the menstrual cycle, the secretory phase is not when menstruation occurs; it's the phase that prepares the uterus for possible implantation of an embryo.
