Pathophysiology Study Set 3

Anaplasia is recognized by loss or organization and a marked increase in nuclear size.

Some tumors initially described as benign can progress to malignant tumors.

Cancer is predominantly a disease of aging.

A hallmark of cancer cells is their immortality.

For the function of tumor suppressor genes to be lost,only one chromosome (allele)of the gene must be inactivated.

Most cancers must acquire mutation in six distinct areas: growth signals,antigrowth signals,evading apoptosis,replicating ability,angiogenesis,and invasion and metastasis.

There is no current evidence that associates obesity with cancer formation.

An increased number of sexual partners has been shown to be related to the incidence of cervical cancer.

There appears to be no relation between the incidence of melanoma and age at the time of exposure to excessive UV radiation.

The term "neoplasm" can refer to a benign tumor.

Which are cancers arising from connective tissue tissues?

Carcinoma refers to abnormal cell proliferation originating from which tissue origin?

What are characteristics of cancer in situ?

Cells from a muscle tumor show a reduced ability to form new muscle and appear highly disorganized.This is an example of:

What are tumor cell markers?

How are tumor cell markers used?

Intestinal polyps are benign neoplasms and the first stage in development of colon cancer.These findings support the notion that:

What is autocrine stimulation?

What is apoptosis?

Many cancers create a mutation of ras.What is ras?
