According to the 8th Edition of the AJCC Breast Cancer Staging Guidelines, clinical staging of breast cancer is primarily determined by tumor size, lymph node involvement, and the presence or absence of distant metastasis. This system is crucial for directing treatment strategies and predicting patient outcomes.

Firstly, tumor size is a critical indicator for classifying breast cancer as early or advanced. Generally, a tumor diameter of less than 2 centimeters is indicative of early-stage breast cancer, while a diameter greater than 5 centimeters suggests a later stage. Secondly, lymph node involvement is a key determinant in assessing the spread of cancer. The presence of cancer cells in nearby lymph nodes typically signifies a more advanced stage of the disease. Lastly, the presence or absence of distant metastasis is the most significant criterion for identifying advanced breast cancer. If cancer cells have disseminated to other parts of the body via the bloodstream or lymphatic system, such as to the bones, lungs, or liver, the cancer is considered advanced.

For individuals diagnosed with breast cancer, it is imperative to seek timely medical care and adhere to standardized treatment protocols. Patients should work with their physicians to develop a personalized treatment plan and strictly follow medical instructions. Additionally, maintaining healthy lifestyle habits, such as a balanced diet and regular physical activity, can enhance physical fitness and immune function, thereby better equipping patients to face the various challenges encountered during treatment.
