According to the National Cancer Institute, tumor size is a key factor in determining breast cancer stage and treatment options. Size plays a crucial role in understanding breast tumors and planning appropriate treatments. This comprehensive guide breaks down tumor classifications into three main categories (T1, T2, and T3), helping you understand what different measurements mean for treatment options. Each category provides clear measurements in both millimeters (mm) and centimeters (cm), along with typical treatment approaches and important considerations.

This breast cancer tumor size chart serves as a general guide to help you better understand your diagnosis and have more informed discussions with your healthcare team. Remember that while size is important, it’s just one of several factors your medical team considers when creating your personalized treatment plan.

The American Cancer Society emphasizes that early detection of small tumors often leads to more treatment options.

T2 Category: The Middle Ground
