Breast lumps epidemiology and demographics
Introduction
Overview
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.

- The prevalence of benign breast disease is approximately 68% among all breast diseases.[2]
- Approximately 60% of benign breast diseases occur in left breast and 40% in the right breast.
- 100% of definite palpable lumps are characteristics of fibroadenoma, phyllodes tumor, and adenomyoepithelioma.
- 64% of lumps located in upper outer quadrant, 26% of lumps in lower outer quadrant, 10% of lumps in upper inner quadrant.
Age
Age-specific incidence rate of benign breast diseases.[1]
- The incidence rate of fibrocystic disease is 137 per 100,000 in women aged 25-29 years, 411 per 100,000 in age of 40-44 years and 387 per 100,000 in 45-49 years.
- The incidence rate of fibroadenoma is 115 per 100,000 in women aged 20-24 years.
- The peak incidence rate of fibroadenoma is between 15-35 years.[3]
- Fibrocystic disease, phyllodes tumor, and adenomyoepithelioma are usually seen in 3rd and 4th decade of life.[2]
