### 3/5 — Staging Error

*2024-05-14*

This app incorrectly calls T1-T2bN3 Stage IIIC when it should be IIIB

### 5/5 — Good updates

Thanx for this great update to the last updated copy of the TNM staging system. 
Keep your intention.

### 1/5 — Not updated

As far as I can tell, this has not been updated to the 8th edition which makes it inaccurate and largely worthless.

### 5/5 — MD

Very useful app!  Allows rapid determination of Staging with accurate descriptions of TNM classifications. Very useful clinically with patients and in conferences.

### 5/5 — Simple and quick
