Breast Cancer Epidemiology

Breast cancer develops in the lining cells (epithelium) of the glandular tissue's ducts (85%) or lobules (15%). Initially, the cancerous growth is confined to the duct or lobule ("in situ"), where it usually causes no symptoms and has a low risk of spreading (metastasis).

These stage 0 cancers may progress over time and invade the surrounding breast tissue (invasive breast cancer), then spread to nearby lymph nodes (regional metastasis) or other organs in the body (distant metastasis). Breast cancer causes death in women due to widespread metastasis.

Breast cancer treatment can be extremely effective, especially if the disease is detected early.
