Actor Sanjay Dutt diagnosed with Stage 3 lung cancer; here is what it means

For the unversed, lung cancer is among the leading causes of cancer deaths in both men and women.

The stage of the cancer is diagnosed by three key criteria called TNM. T refers to the tumour, N refers to Nodes and M refers to Metastasis – how big is the tumour (T), how near it is to the lymph nodes (N), and how far (M) has the disease spread from its original spot.
