Metastatic Cancer Statistics

Metastatic cancer is still stealing the most time and life, with 5 year relative survival at just 30% for metastatic breast cancer and distant stage responsible for 28% of cancer deaths in the United States. Yet the page also tracks what is changing fast, from actionable biomarker eligibility in 52% of advanced non small cell lung cancer to how therapy adoption, costs, and survival benchmarks diverge sharply by tumor type and treatment line.

Statistics that fail independent corroboration are excluded.

Metastatic cancer survival outcomes can look unexpectedly different depending on the tumor type, with distant-stage colorectal patients showing a 1-year relative survival of 35% while metastatic prostate cancer sits at 59% for the same timeframe. Even when treatment starts, real-world patterns reveal gaps such as only 27% of metastatic patients moving to later therapy within 6 months. And behind those individual outcomes are system-level pressures, from distant-stage cancers driving 28% of US cancer deaths to tens of billions in oncology spending and sharply varying response rates across targeted and immune therapies.
