Introduction To Neoplasia

Question 1

What is neoplasia?

Answer 1

Neoplasia is the abnormal growth of cells, characterized by unregulated proliferation, failure to differentiate into the proper cell type, and persistence without external stimuli.

Question 2

What are the causes of neoplasia?

Answer 2

Neoplasia is caused by incorrect specialization, too much cell division, or insufficient apoptosis.

Question 3

How can neoplasia be detected?

Answer 3

Neoplasia may form a mass or lesion and is categorized as either benign or malignant.

Question 4

What is the key difference between benign and malignant tumors?

Answer 4

Malignant tumors can infiltrate and spread to nearby and distant tissues, while benign tumors are well-defined and localized.

Question 5

How are the edges of benign and malignant tumors different?

Answer 5

Benign tumors have well-defined edges, while malignant tumors have poorly defined edges, making it difficult to distinguish new growth.
