41
if you get a hysterectomy continue _____ test to r/o _____ or ______cancer
pap; vaginal; vulvular
42
what are the 7 warning signs of cancer
``` change in bowel or bladder habits a sore that does not heal unusual bleeding or discharge thickening or lump in breast or else where indigestion or difficulty swallowing obvious change in a wart or mole nagging cough ```
43
pathologist compares the appearance of cancer cells to the normal surrounding cells
grading
44
classifying a malignancy by the extent of spread within the body
staging
45
what is the framework for determining prognosis and treatment and is done BEFORE treatment begins
staging
46
stage 1
small cancer found only in organ where it originated
47
stage 2
larger cancer that may/may not have spread to the lymph nodes
48
stage 3
larger cancer also in the lymph nodes
49
stage 4
cancer has spread from original site into other organs
50
what does TNM stand for
``` T= size of primary tumor N= number of lymph nodes involved M= extent of metastasis ```
51
in situ=
contained and very small
52
what is the most significant prognostic factor
depth of tumor invasion at time of dx
53
what does M1 mean
cancer has spread to one or more distant parts of the body
54
still in the original tissue layer
in situ
55
still in the original organ
localized
56
spread to nearby lymph nodes or organs
regional
57
spread to sdistant body parts
distant
58
what are tumor markers used for
to monitor for recurrence
59
after being dx and if the marker increases that means the regimen ______; if the marker lowers that means the regimen _______
is not working ; is working
60
carcinoembryonic antigen looks at what and is used to
looks at gastric, lung and breast | is used to determine benefits of tx
61
alfa-fetoprotein AFP is mainly for _____ cancer and is used to determine _______ of treatment
liver; effectiveness
62
cancer antigen 125 (CA-125) is used in
ovarian, breast and pancreas to monitor tx AND recurrence of disease
63
cancer antigen (CA-19-9) is used for
pancreatic and will look at it in cirrhosis pt but is NOT a good screening tool but tells you if treatment is working
64
what are the 6 types of dx surgery
shave, punch, incisional, excisional, fine needle, core needle
65
doen to extract a portion of the lesion for dx reasons when the tumor is TOO LARGE to excise
incisional biopsy
66
2nd most diagnosed cancer in women
breast cancer
67
what are s/s of breast cancer
often painless lump or mass
68
what are risk factors for breast cancer
obese, physical inactivity, alcohol consumption, family hx
69
what are tx for breast cancer
mastectomy, radiation chemo
70
begins in the pigmented cells (flat) and can occur on any surface of the skin
melanoma
71
begins in the basal layer of skin after repeated exposure to the sun and mostly occurs on the face (fair skin)
basal cell
72
most common skin cancer among people with darker skin and typically on the legs and feet
squamous cell
73
clarks stage 1
confined
74
clarks stage 2
in the dermis
75
clarks stage 3&4
deeper in the dermis but still contained in the skin
76
clarks stage 5
in an organ
77
risk factors of skin cancer
``` sunlight/UV severe sunburns tanning family hx fair pale skin medications or medical cond ```
78
what are 4 signs of skin CA
change in an existing mole (shape, color, size of feel) hard or lumpy skin surface of skin oozes or bleeds and no healing itchy, tender, painful skin
79
what is the ABCDE method of skin cancer
``` Asymmetry Border Color Diameter Evolution ```
80
if skin cancer is present the diameter of the mole is typically
larger than 6mm
81
skin CA dx is usually done by ______ then staging is based on ______
biopsy ; TNM
82
a TNM of 0=
confined
83
a TNM of 1=
deeper into the dermis
84
a TNM of 2=
1-2mm, 2-4mm, >4mm)
85
a TNM of 3=
is in the lymph nodes but not in an organ
86
a TNM of 4=
everywhere
87
what are the different types of biopsys
shave, punch, incisional, excisional
88
depending on type and stage of skin CA, what treatment is done?
excision, surgery, chemo, radiation, biological therapy
89
why is chemo done a few weeks after surgery
because chemo makes a person more sick and unable to heal as fast so they want the person to heal first before starting chemo
90
what are a few ways to reduce the chance of getting skin cancer
limit sun exposure, sun screen (SPF 30), wear protective clothing, stay away from sun lamps or tanning booths, wear a hat with brim, regularly check skin for changes in moles
