What does SVC syndrome do
Vessels of face, neck, arms, upper chest swell with blood causing swelling
Explain paraneoplastic syndrome
Distant effects on the body due to changes to the bodies metabolism brought on by the tumor
Metabolic effects caused by paraneoplastic syndrome
Hypercalcemia
Excess growth of bones (fingertips)
Blood clots
Primary goal of diagnostic procedures (cancer)
