    • Tumor Affected pomp; bombast; swelling words or expressions; false magnificence or sublimity. "Better, however, to be a flippant, than, by a revolting form of tumor and perplexity, to lead men into habits of intellect such as result from the modern vice of English style."

  • Interesting fact: The major side effects from abusing anabolic steroids can include liver tumors and cancer, jaundice (yellowish pigmentation of skin, tissues, and body fluids), fluid retention, high blood pressure, increases in LDL (bad cholesterol), and decreases in HDL (good cholesterol).

    • n tumor A swell or rise of any kind.
    • n tumor In medicine: A swelling; one of the four necessary accompaniments, according to the older pathologists, of inflammation—namely, color, dolor, rubor, et tumor (heat, pain, redness, and swelling).
    • n tumor An abnormal prominence existing upon any of the cutaneous, mucous, or serous surfaces in any part of the body, and not due to acute inflammation. A tumor is usually a new formation of tissue foreign to the part in which it exists, and is thus distinguished in general from hypertrophy, though a hypertrophy may occasionally be so localized as to constitute a true tumor. A neoplasm is called a tumor when it forms a prominence on any surface. A swelling may be acute or chronic, and may be circumscribed or diffuse; a tumor is a chronic circumscribed swelling.
    • n tumor A swelling port or style; tumidity; bombast.
