Yes, a 13mm tumor is considered relatively big, particularly when considering the early stages of tumor development and cancer staging.
Based on classifications used in cancer staging, specifically T stages:
- T1mi tumors are microscopic (less than 1 mm).
- T1a tumors are larger than 1 mm but not more than 5 mm.
- T1b tumors are larger than 5 mm but not more than 10 mm.
- T1c tumors are larger than 10 mm but not more than 20 mm.
Therefore, a 13mm tumor falls into the T1c category. The term "big" is subjective and depends on the context (e.g., location in the body, type of cancer, and comparison to other tumors). However, in the context of early tumor classification, 13mm is significant enough to be considered relatively "big" compared to earlier stages. The significance also depends on where the tumor is located. A 13mm tumor in the brain would be considered very large, whereas a 13mm tumor in the lung might be less concerning.
