25
Which is a characteristic of a malignant tumor?
They invade blood vessels and lymphatics and have distant metastases. ## Footnote Malignant tumors have no capsule, which allows them to spread readily.
26
Which statement is true regarding the staging of cancer?
Cancers that have spread regionally are stage 3. ## Footnote Cancer confined to the organ of origin is stage 1; locally invasive is stage 2; spread to regional structures is stage 3; and spread to distant sites is stage 4.
27
Which statement is true regarding metastasis?
Metastasis is a complex process that requires cells to have many new abilities, including the ability to invade, survive, and proliferate in a new environment. ## Footnote Metastasis is highly inefficient; to metastasize, a cancer cell must surmount multiple physical and physiologic barriers.
28
Which statement characterizes radiation therapy?
Radiation is used to kill cancer cells while minimizing damage to normal structures. ## Footnote Effective cell killing using radiation requires good local delivery of oxygen.
29
Which virus is linked to the development of cancer?
Hepatitis B, Human papillomavirus, Epstein-Barr virus, Hepatitis C. ## Footnote Hepatitis B and C are linked to liver cancer; Epstein-Barr virus can lead to B-cell lymphomas; Human papillomavirus is linked to cervical and other cancers.
30
Carcinoma in situ is characterized by which changes?
Cells remain localized in the glandular or squamous cells. ## Footnote Carcinoma in situ refers to preinvasive epithelial malignant tumors that have not invaded surrounding tissue.
31
What are tumor cell markers?
Hormones, enzymes, antigens, and antibodies that are produced by cancer cells. ## Footnote Tumor markers are substances produced by both benign and malignant cells found in or on the tumor cells or in bodily fluids.
32
What are characteristics of benign tumors?
Benign tumors include the suffix -oma. ## Footnote Benign tumors are usually encapsulated and well-differentiated, retaining some normal tissue structure.
33
What is the most commonly reported symptom of cancer treatment?
Fatigue. ## Footnote Fatigue is the most frequently reported symptom of cancer and cancer treatment.
34
What is the most common route for distant metastasis?
Liver, Lung, bone ## Footnote These organs are commonly involved in distant metastasis.
35
Carcinoma refers to abnormal cell proliferation originating from which tissue origin?
Epithelial cells. ## Footnote Only cancers arising from epithelial cells are called carcinomas.
36
What is one function of the tumor cell marker?
To screen individuals at high risk for cancer. ## Footnote Tumor markers can be used to help diagnose a specific type of cancer and to follow the clinical course of a tumor.
37
It has been determined that a patient’s tumor is in stage 2. How does the healthcare professional describe this finding to the patient?
Cancer is locally invasive. ## Footnote Cancer confined to the organ of origin is stage 1; locally invasive is stage 2.
38
What does the health professions student learn about benign tumors?
The cells are well-differentiated. ## Footnote A benign tumor is well-differentiated with its tissue appearing similar to the tissue from which it arose.
39
Which cancers are associated with chronic inflammation?
Colon, Urinary bladder, Thyroid gland. ## Footnote Some organs are more susceptible to chronic inflammation's oncogenic effects.
40
Which statement is true regarding obesity? (Select all that apply.)
It has been increasing rapidly over the past 20 years. Obesity is linked to an increased risk of developing many cancers.
41
A person drinks alcohol in excessive quantities. Which areas are likely to develop cancer related to alcohol consumption? (Select all that apply.)
Larynx, Pharynx, Liver, Oral cavity ## Footnote Cancers of the gastrointestinal system are linked to alcohol and include cancer of the oral cavity, larynx, pharynx, hypopharynx, esophagus, and liver.
42
Which statements are true regarding melanoma? (Select all that apply.)
Individuals with a history of sunburns are at risk for melanoma. Melanoma is the most lethal form of skin cancer. Individuals with fair skin and hair color are at risk for melanoma. ## Footnote Melanoma is the most lethal form of skin cancer and can occur on any skin surface. Risk factors vary for different types of skin cancer but include lighter natural skin color, family history of skin cancer, personal history of skin cancer, exposure to the sun, history of sunburns, indoor tanning, skin that burns easily, blue or green eyes, blonde or red hair, and certain types of moles.
43
Physical activity reduces the risk of which type(s) of cancer? (Select all that apply.)
Breast, Liver, Colon
44
Which of the following is the most common sexually transmitted virus?
HPV
45
Which substance has been shown to increase the risk of cancer when used in combination with tobacco smoking?
Alcohol ## Footnote Alcohol interacts with smoke, increasing the risk of malignant tumors, possibly by acting as a solvent for the carcinogenic chemicals in smoke products.
46
Which environmental factors have been shown to have greatest significant effect on the frequency of genetic mutations in humans? (Select all that apply.)
Obesity, Tobacco use, Radiation exposure
47
Research has shown a link between cancer and which sexually transmitted disease?
Human papillomavirus ## Footnote Human papillomavirus (HPV) is the most common sexually transmitted virus in the United States. High-risk HPVs can cause cancer.
48
What are the significant risk factors associated with the development of skin cancers? (Select all that apply.)
Light-colored hair, Freckles, Pale eyes, Fair skin
49
Which blood type is considered the universal donor?
O- ## Footnote The book just says O.
50
What are the four blood types?
A, B, AB, O (can be positive or negative depending on Rh factor).
51
Which blood type is the universal recipient?
AB+ ## Footnote The book says AB.
52
What is immunologic homeostasis?
Steady state of tolerance to self-antigens or lack of immune reaction against environmental antigens.
53
What is alloimmunity?
Immune system of one individual produces an immunologic reaction against tissues of another individual.
54
What is hypersensitivity?
Altered immunologic response to an antigen that results in disease or damage to the host.
55
What is an allergy?
Deleterious effects of hypersensitivity to environmental antigens.
56
What blood type does a person with type O blood need for a transfusion?
O ## Footnote Type O individuals have neither A or B antigen but have both anti-A and anti-B antibodies.
57
What is characteristic of Carcinoma in situ?
Cells remain localized in the glandular or squamous cells.
58
What are the most common sites where cancer spreads?
Bone, liver, lung.
59
What condition associated with cancer usually occurs because of malnutrition, chronic bleeding, and resultant iron deficiency?
Anemia.
