  1. How Cancer Spreads Through the Body: Cancer cells spread by breaking away from the original tumor, invading nearby tissue, entering blood or lymph vessels, traveling to a new location, and then growing and forming new tumors, often avoiding the immune system.
  2. Most Common Sites for Cancer Metastasis: Cancer commonly spreads to the bones, liver, and lungs, though it can metastasize to almost any part of the body.
  3. Key Methods for Diagnosing Metastatic Cancer: Doctors diagnose metastatic cancer using various methods including imaging tests (CT, MRI, PET, bone scans, ultrasound), biopsies, blood tests, and biomarker or genomic testing.
