Question

Quizplus · Accepted Answer

Benign tumors are noninvasive and do not spread to other parts of the body. They are usually not life-threatening, although they can cause problems if they grow too large or press on organs or tissues. Malignant tumors, on the other hand, are invasive and can spread to other parts of the body. Secondary tumors refer to tumors that have spread from their original site to other parts of the body, while metastatic tumors specifically refer to tumors that have spread to distant sites via the bloodstream or lymphatic system.
