Radiation Oncology Exam 1 with correct answers
Screening Test - CORRECT ANSWERS ✔✔Test used to detect cancer (or other
diseases) at an earlier, easier to treat stage
Can be a blood test, imaging or tissue sampling
Prevalence - CORRECT ANSWERS ✔✔The probability of a disease in a population
at a certain time
Sensitivity - CORRECT ANSWERS ✔✔Screening tests should be high in this,
meaning most of the time if a person has the disease, the test will be positive
The ability of a test to give a true-positive result
Specificity - CORRECT ANSWERS ✔✔If the test is positive, a person may or may not
have the disease, but doctors are alerted that person needs more evaluation
The ability of a test to obtain a true negative result
Incidence - CORRECT ANSWERS ✔✔Probability that a patient without disease
develops the disease during a time interval
Ultrasound - CORRECT ANSWERS ✔✔Uses sound waves to look at anatomy. No
radiation
Fine Needle Aspirate (FNA) - CORRECT ANSWERS ✔✔A small needle is placed in
the tumor
, Core Needle Biopsy (Core) - CORRECT ANSWERS ✔✔Large needle used to collect
tissue. We get a better look at the architecture of the tissue
Incisional Biopsy - CORRECT ANSWERS ✔✔A surgeon cuts out a piece of the
tumor
Excisional Biopsy - CORRECT ANSWERS ✔✔A surgeon removes the entire tumor,
or node. For small tumors only
Pathologist - CORRECT ANSWERS ✔✔A physician who specializes in diagnosing
disease by looking under the microscope, and/or by analyzing samples of bodily
fluids. They also study cadavers. They will write a report about the cancer that goes
into the patient's medical chart
-ectomy - CORRECT ANSWERS ✔✔As a word ending, means removal of something
Lumpectomy - CORRECT ANSWERS ✔✔Removal of the lump/part of the breast
tissue
Mastectomy - CORRECT ANSWERS ✔✔Removal of the entire breast
Sentinel Lymph Node Procedure - CORRECT ANSWERS ✔✔The idea that cells from
the tumor can slough off and travel to lymph nodes by small lymphatic channels
(tubes). The channels will drain to one or two nodes first, then to other nodes. The
first nodes are called SENTINEL NODES. If the first sentinel nodes are negative, it is
unlikely that other nodes will be positive
