Tumor vs. Cancer: What's the Difference?

No, a tumor does not always equal cancer. A tumor is a general term for an abnormal growth of cells, which can be either benign (non-cancerous) or malignant (cancerous). Benign tumors do not invade nearby tissues or spread to other parts of the body, while malignant tumors can invade nearby tissues and spread to other parts of the body, leading to cancer.
