The most common ways in which cancer spreads are through the bloodstream and lymphatic system. Cancer cells can break away from the primary tumor and enter these systems, allowing them to travel to other parts of the body and form secondary tumors. Local spread and seeding of the respiratory tract may occur in certain types of cancer, but they are not as common as metastasis through the bloodstream or lymphatic system. Airborne fluids are not a common way for cancer to spread.
