Metastatic And Advanced Cancers

Metastatic cancer involves cells detaching via bloodstream or lymphatics, establishing new tumors; advanced stages (III/IV) feature local invasion or distant spread, differing by primary origin like breast or lung. Over 90% of cancer deaths stem from metastasis.?

Symptoms and Diagnosis

Signs vary by site—bone pain, shortness of breath, jaundice, headaches; PET-CT, MRI, biopsies, and biomarkers (CEA, CA-125) stage disease and guide therapy. Liquid biopsies detect circulating tumor DNA for monitoring.?

Treatment Strategies

Systemic options dominate: chemotherapy shrinks tumors, targeted therapies (e.g., HER2 inhibitors) hit mutations, immunotherapy (PD-1 blockers) boosts immunity, hormone therapy suits breast/prostate; localized radiation/surgery palliate symptoms. Goals focus on progression-free survival, with some living years post-diagnosis
