Is a tumor harmless

A tumor is not inherently harmless; it can be either benign or malignant. Benign tumors do not spread to other parts of the body and are generally not life-threatening, but they can still cause problems if they press on vital organs or tissues. Malignant tumors, on the other hand, are cancerous and can invade nearby tissues and spread, making them potentially dangerous. Therefore, the nature and behavior of the tumor determine its level of harm.
