(2) Rapid growth of cells. (3) Invasion and damage to the surrounding tissue. Cancer specifically refers to malignant neoplasms, which are cancerous and invasive. Benign tumours remain confined to their original location. Thus, D is not included in the answer. The malignant tumours, on the other hand are a mass of proliferating cells called neoplastic or tumour cells. These cells grow very rapidly, invading and damaging the surrounding normal tissues.
