18 Questions
What is the extent to which neoplastic parenchymal cells resemble their normal parent cells called?
Differentiation
What term is used to describe the irreversible loss of differentiation in neoplastic cells?
Anaplasia
What is the common term for a malignant neoplasm?
Cancer
Which type of mass lacks the ability to invade neighboring tissue or metastasize?
Benign tumor
Which characteristic of cancer cells involves the abnormal growth and potential invasion of tissues and distant organs?
Metastasis
When a tumor progresses beyond a certain stage, what may it cause if not successfully removed?
Death of the affected patient
What is the term for non-neoplastic growth disorders characterized by an increase in the number of cells?
Hyperplasia
Which type of tumor arises from a single transformed cell?
Malignant
What term is used to describe the process where cancer cells spread from the primary site to other parts of the body?
Metastasis
In tumors, what term refers to the ability of cancer cells to invade surrounding tissues and organs?
Dysplasia
What characterizes benign tumors in terms of growth rate compared to malignant tumors?
Slow growth rate
Which term describes the process where cancer cells avoid apoptosis and continue to divide rapidly?
Neoplasia
What is a distinguishing characteristic between benign and malignant tumors in terms of differentiation?
Benign tumors are well-differentiated, whereas malignant tumors lack differentiation.
What distinguishes the rate of growth between benign and malignant tumors?
Benign tumors have slow and progressive growth, while malignant tumors have rapid growth.
Which characteristic is associated with local invasion in tumors?
Benign tumors are locally invasive, infiltrating surrounding tissue.
Which feature is commonly observed in metastasis?
It is more likely in larger and undifferentiated primary tumors.
What characterizes the rate of growth in malignant tumors?
Malignant tumor growth can vary from slow to rapid, with numerous abnormal mitotic figures.
Which statement describes the local invasion of malignant tumors?
Malignant tumors are locally invasive, infiltrating surrounding tissues due to the absence of a capsule.
Test your knowledge on differentiating between benign and malignant tumor characteristics. Identify key features such as differentiation, stromal hyalinization, and circumscription in tumors like leiomyoma-uterus and hepatocellular carcinoma.
