Which term describes a malignant growth due to abnormal and uncontrolled cell division?

• A. Allergies
• B. Cancer
• C. Goiter
• D. Diabetes mellitus

Answer: (B)

Cancer is a malignant growth caused by abnormal and uncontrolled cell division. When cellular regulatory mechanisms fail, cells divide without normal checks, can evade death, and gain the ability to invade nearby tissues and spread to distant sites (metastasis). This unchecked growth distinguishes cancer from benign tumors, which do not invade or metastasize. The other options refer to different conditions: allergies involve immune reactions to substances, goiter is enlargement of the thyroid gland, and diabetes mellitus is a metabolic disorder with high blood glucose due to insulin problems.
