Tumor size plays a critical role in the diagnosis, prognosis, and treatment of cancer. Larger tumors are often associated with a higher stage of disease, which can indicate more extensive spread to other tissues or organs. The exact size of a tumor is typically measured in centimeters (cm) using imaging techniques such as MRI, CT scans, or ultrasound. For example, in breast cancer, tumors are often categorized as T1, T2, T3, or T4, based on their size and extent of spread to nearby tissues.
