TNM staging classifies a tumor’s size, lymph node involvement, and metastasis; stage grouping combines these into prognostic categories. Stage migration happens when improved diagnostics, like better scans, shift patients to earlier stages without changing their actual disease—artificially improving survival statistics for each stage. Analyzing registry data, I see this effect inflating outcomes, especially in urban centers with advanced imaging, while rural areas seem to have "worse" survival simply due to older detection methods. It reminds me of my old pushcart—if you only measure the fruit sold near the mall, your accounts look brilliant, but it misses the struggle in the quieter lanes where my bapa waits.
