Answer 1

Metastatic cancer is commonly called stage IV cancer or advanced cancer. It is the advance state or chronic metastans not only all site of origin, all distant parts of the body gets affected by the cells, almost all the organs get damaged and treatment is nearlly impossible.

Stage 4 cancer cells have metastasized, spreading to distant areas in the body, including lymph nodes, the brain, prostate, spine or the lining of the heart. Stage 4 is the final mesothelioma stage and considered terminal. The average life expectancy for stage 4 mesothelioma is less than 12 months.

Therefore, Option 4 is correct.
