30
What are the 4 inspection/ palpation mentioned in the slides?

31
What does ABCDE stand for?
``` A = asymmetrical B = "borders" (irregular = "Coast of Maine sign"), C = "color" (variegated) D = "diameter" (larger than 6 mm—the size of a pencil eraser) E = evolving over time ```

Metaplasia Dysplasia Hyperplasia
40
What are metaplasic cells?

expansion of immature cells with decrease in the number and location of mature cells
42
What are hyperplasic cells?
increased number of cells, which may signal a pre-cancerous or cancerous process
43
What does PSA stand for?
Prostate specific antigen
44
What does PSA relate to?
~Elevated levels related to prostate hyperplasia and prostate cancers ~Not just total but ratio bound to total also important ~High risk for prostate cancer if > 65 years old and/or African-American male
45
What is a PAP test?
It is a test where cervical tissue sample taken with regular pelvic exam
46
Why should you have a PAP test?
~Looking for abnormal cells – dysplasia or metaplasia | ~High sensitivity and specificity
47
What causes an increased risk for cervical cancer?
``` ~Frequent intercourse ~Multiple partners ~STDs – particularly HPV & chlamydia ~Smoking ~Stress ~Oral contraceptives ```
48
How many stages are there for Pap Staging?
7 *I will list the stages in cards, but she said we don't have to know them by heart. It's more so you can get a better idea of the staging.
49
Stage 1 for Pap Staging
Negative for intraepithelial lesion or malignancy.
50
Stage 2 for Pap Staging
Atypical squamous cells of undetermined signficance (ASC-US).
51
Stage 3 for Pap Staging
Low grade squamous intraepithelial lesion (LSIL). This includes HPV and mild dysplasia.
52
Stage 4 for Pap Staging
Atypical squamous cells — cannot exclude high grade SIL (ASC-H).
53
Stage 5 for Pap Staging
High grade squamous intraepithelial lesion (HSIL) encompassing moderate dysplasia (CIN2), as well as CIN 3, which includes severe dysplasia carcinoma in situ (CIS).
54
Stage 6 for Pap Staging
Squamous cell carcinoma
55
Stage 7 for Pap Staging
Abnormal glandular cells including atypical glandular cells of undetermined significance (AGUS): endocervical adenocarcinoma; endocervical adenocarcinoma in situ; endometrial adenocarcinoma; extrauterine adenocarcinoma; adenocarcinoma, NOS
