What do we call abnormal tissue growths that can be benign or malignant?

• A. Tumors
• B. Neoplasms
• C. Cysts
• D. Lesions

Answer: (B)

The term that best describes abnormal tissue growths, whether benign or malignant, is neoplasms. Neoplasms encompass all forms of new and abnormal tissue growth, which include tumors. Both benign neoplasms (like fibromas and lipomas) and malignant neoplasms (like cancers) fall under this category.

While tumors are often used interchangeably with neoplasms in casual conversation, not all tumors are neoplasms per the strictest definition; for instance, some tumors can be non-neoplastic. Cysts refer specifically to closed pockets of tissue that can contain fluid, air, or other substances, which is a narrower definition and does not capture the full scope of both benign and malignant growths. Lesions are general abnormalities in tissue that can be the result of various conditions and do not specifically indicate the growth of new tissue like neoplasms do. Thus, the term neoplasms is the most accurate and comprehensive choice for describing the spectrum of abnormal tissue growths.
