Abstract

Breast cancer is one of the most common cancers globally, affecting millions of people each year. Understanding the stages of breast cancer is critical for diagnosis, treatment planning, and prognosis. The staging system describes the extent of cancer spread, providing a roadmap for medical professionals to assess the severity of the disease and develop appropriate treatment strategies. This article explores the different stages of breast cancer, from stage 0 to stage IV, focusing on the factors that influence staging, including tumor size, lymph node involvement, and metastasis. We will also highlight how the staging system helps guide treatment decisions and predict patient outcomes.
