Breast Cancers
Breast cancer is the most common cancer in women worldwide. Outcomes are excellent when the disease is detected early and treated appropriately using modern, evidence-based therapies. Although far more common in women, breast cancer can also occur in men.
Overview
Breast cancer occurs when cells in the breast grow uncontrollably and form a tumor.
It usually begins in the milk ducts (ductal cancer) or lobules (lobular cancer).
Breast cancer can occur at any age but is more common after 40–50 years.
There are multiple subtypes including hormone receptor-positive, HER2-positive, and triple-negative breast cancer.
Treatment is personalized based on tumor biology, stage, and patient factors.
