QUESTIONS WITH ACCURATE
SOLUTIONS
1) Which of the following statements about tumors is FALSE:
a) the speed of growth of a tumor type is very predictable
b) benign tumors can have serious consequences if they impede
organ function
c) secondary tumors (metastases) may be larger than the
primary tumor -- Answer ✔✔ a) the speed of growth of a tumor
type is very predictable
2) A tumor showing little or no sign of a specific type of epithelial or
mesenchymal origin is termed: -- Answer ✔✔ anaplastic
3) Excessive exposure to UV radiation in sunlight is known to increase
the incidence of: -- Answer ✔✔ melanoma
4) Which of the following statements is FALSE?
a) biochemical secretions of tumor cells may induce stromal
changes
, b) the stroma has an important role in providing a connective
tissue framework and an adequate blood supply for tumor
growth
c) stromal changes occur independently of tumor growth --
Answer ✔✔ c) stromal changes occur independently of tumor
growth
5) Which of the following statements is FALSE?
a) sarcomas are malignant tumors of mesenchymal origin

c) adenomas are malignant tumors of glandular epithelium --
Answer ✔✔ c) adenomas are malignant tumors of glandular
epithelium
they're benign

the lining of bronchi (as occurs in the airways of long-term smokers)
is termed: -- Answer ✔✔ metaplasia
7) The activation of protooncogenes leads to: -- Answer ✔✔ promotion
of cell growth without growth-promoting signals
8) Tumor cells develop a limitless potential for replication due to: --
Answer ✔✔ activation of telomerase
9) All agents that function as tumor promoters act to induce: -- Answer
✔✔ cell proliferation
, 10) The most significant behaviours in determining whether a tumour
is malignant or benign are the ability to invade and: -- Answer ✔✔
develop metastases
11) Breast cancer, colorectal cancer and lung cancer are: -- Answer
✔✔ the leading causes of cancer death in women

14) a neoplasm/tumor is: -- Answer ✔✔ the development of a mass of
abnormal tissue
-abnormal cell differentiation, maturation and control of growth
15) In normal cell development, ________ must = _________ -- Answer
✔✔ cell proliferation rate must = differentiation rate
