what is a benign neoplasm originating from adipose tissue called

Lipoma

What are malignant neoplasms arising from connective tissue cells called?

sarcomas

Which of the following is a characteristic of a benign tumor

cells appear relatively normal

Which factor provides the basis for the grading of newly diagnosed malignant tumors?

degree of differentiation of the cells

A warning sign of possible cancer would any of the following EXECPT

sudden development of fever, nausea, and diarrhea

the common local effects of an expanding tumor mass include

obstruction of a tube or duct
cells necrosis and ulceration

Which of the following does paraneoplastic syndrome refer to

the effects of substances such as hormones secreted by the tumor cells

which term refers to the spread of malignant cells through blood and lymph to distant sites

metastis

one reason for staging a malignant tumor at the time of diagnosis is to

determine the best treatment and prognosis

the process of carinogenesis usually begins with

an irreversible change in the cell DNA

what would be an external source of ionizing radiation

Gamma rays delivered by a cobalt machine

Radiation therapy destroys

primarily rapidly dividing cells

The most critical adverse effects of chemotherapy and radiation therapy are

thrombocytopenia and leucopenia

Chemotherapy usually involves a combination of drugs in order to:
1. reduce the adverse effects.
2. guarantee that all cancer cells are destroyed.
3. be effective in more phases of the cell cycle.
4. totally block the mitotic stage.

reduce the adverse effects.
be effective in more phases of the cell cycle.

why does over cancer have a poor prognosis

specific signs rarely appear until after secondary tumors have develop

select the correct pair representing a malignant tumor and its marker

colon cancer: carcinoembryonic antigen (CEA)

antiangiogenesis drugs act on a malignant tumor by

reducing blood flow and nutrient supply to tumors cells

the development of neutropenia during chemotherapy for cancer means

the patient is at high risk for infection

malignant brain tumor

spread to other parts of CNS

Identify the common dose-limiting factor for chemotherapy:

bone marrow depression

Glucocorticoids are often prescribed during a course of chemotherapy and radiation because

inflammation around the tumor may be reduced

Vomiting frequently follows a chemotherapy treatment because

The gastrointestinal tract is irritated
the chemicals stimulate the emetic center

What type of normal cells are often damaged during chemotherapy and radiation treatments?

epithelial cells

Remission for cancer is generally defined as a period in which:

signs and symptoms are absent

all of the following are correct statements about skin cancers EXCEPT

they are difficult to diagnose and treat

High-risk factors for cancer include:
1. human papillomavirus.
2. chronic irritation and inflammation.
3. repeated sun exposure.
4. high family incidence.

all the above

the term apoptosis refers to

programmed cell death

the warning signs of cancer include
1. unusual bleeding
2. change in a wart or mole
3. a new solid lump, often painless

all the above

a classification process that applies to a specific malignant tumor and describes the extent of the disease at a given time is called

staging

benign tumor can often be differentiated from malignant tumors because benign tumors

are encapsulated and slow growing

Benign tumors in the brain are often life-threatening because they:

create excessive pressure within the skull

Drugs or agents that augment the natural immune response in the body to improve identification and removal of abnormal cells are called:

biological response modifiers

the method that can be used as an alternative to surgical removal of a tumor by using heat generated by a needle inserted into the tumor is referred to as

radio-frequency ablation

Staging systems used to classify a malignant tumor at the time of diagnosis are based on which of the following factors?

size of the tumor, involvement of lymph nodes, metastases

on the general effects of a malignant cancer is cachexia, which is

severe tissue wasting

What are malignant neoplasia arising from connective tissues called?

Malignant neoplasms derived from epithelial cells are called carcinomas. Those derived from mesenchymal (connective tissue) cells are called sarcomas.

What are malignant neoplasms arising from glandular tissue cells called?

A malignant tumor arising from epithelial cells. Carcinomas that arise from glandular epithelium are called adenocarcinomas, those that arise from squamous epithelium are called squamous cell carcinomas, and those that arise from transitional epithelium are called transitional cell carcinomas.

What is another name for malignant neoplasms?

A malignant neoplasm (NEE-oh-plaz-um) is another term for a cancerous tumor. The term “neoplasm” refers to an abnormal growth of tissue. The term “malignant” means the tumor is cancerous and is likely to spread (metastasize) beyond its point of origin.

What is benign neoplasm originating from adipose tissue called a group of answer choices?

Lipoma: A lipoma forms from fat cells. This benign fatty tumor grows just below your skin. It's the most common type of benign tumor. Lymphangioma: This type of benign neoplasm develops in your lymphatic system.
