The incidence rate of breast lumps is not particularly clear due to the fact that [[breast lumps]] is not considered as a life threatening condition and majority of the women who receives medical therapies or surgeries come into account.The prevalence of [[benign]] breast disease is approximately 68% among all breast diseases and the incidence of breast diseases is higher on the left upper/outer quadrant of breast. [[Fibrocystic Disease|Fibrocystic diseases]] are more frequent in age of 40-44 years and [[fibroadenoma]] is more frequent between 15-35 years. [[Fibroadenoma]] rate is higher in black women. African-American women have worse [[prognosis]] and higher [[mortality rate]] in comparison European American women.

Overview

The incidence rate of breast lumps is not particularly clear due to the fact that breast lumps is not considered as a life threatening condition and majority of the women who receives medical therapies or surgeries come into account.The prevalence of benign breast disease is approximately 68% among all breast diseases and the incidence of breast diseases is higher on the left upper/outer quadrant of breast. Fibrocystic diseases are more frequent in age of 40-44 years and fibroadenoma is more frequent between 15-35 years. Fibroadenoma rate is higher in black women. African-American women have worse prognosis and higher mortality rate in comparison European American women.
