firm, rubbery, size of a walnut

any abnormal growth of new tissue
malignant neoplasms multiply and spread to distant parts of the body through the blood stream or lymph system
increase in the number of cells in an organ or tissue, number of cells gets bigger
increase in the size of cells and subsequently the size of an organ, actual cells get bigger
one adult cell type is replaced by another cell type
irreversible change where adult cells regress to more primitive state
slow growth, remains localized, usually encapsulated, smooth, well defined, resembles parent tissue, crowds normal tissue, rarely fatal
characteristics of benign neoplasms
growth rate varies, metastasizes, rarely encapsulated, irregular, does not resemble parent tissue, invades normal tissue, may recur, fatal without treatment
characteristics of malignant neoplasms
described according to the site of the primary tumor, the type of tissue involved or the person who identified it
cancer of grandular tissue
cancer occurring in infection fighting tissue, lymphatic tissue
cancers occurring in blood forming organs
cancers occurring in epithelial tissues
cancers occurring in connective tissue
abnormal cell invasion
phase one of tumor formation
tumor is there but not invading, easy to get out
phase two of tumor formation
angiogenesis/invasion occurs
phase three of tumor formation
phase four of tumor formation
cancer staging
determines the extent of the spread of cancer
T- tumor, N - node, M - metastasis
TNM staging classification system
the higher the number the more cancer
rule when staging and grading cancer
tumor cannot be assessed
no evidence of primary tumor
carcinoma in situ
T1, T2, T3
progressive increase in tumor size and involvement
carcinoma in situ
tumor is there but not invasive or moving
regional lymph nodes cannot be assessed
no regional nodes metastasis
N1, N2, N3
increasing lymph node involvement
not assessed
no known distant metastasis
distant metastasis present, specify sites
based on the degree of malignancy which is determined by the ability of the cell to perform its function
what is the most definitive way to diagnosis cancer
watch for bleeding
priority when a tissue biopsy has been taken
determines the difference between solid mass and fluid filled cyst
to know if the tumor has come back
why would a patient receive a carcinoembryonic antigen(CEA) and prostate specific antigen(PSA) test a year after chemotherapy
PSA ia elevated, blood with DRE
when is a transrectal ultrasound of the prostate done
no stimulants before the test and not pregnant nurses or patients
priority when doing a transrectal ultrasound of the prostate
to remove all malignant cells
goal of surgery for cancer
curative surgery
to heal or restore health
palliative surgery
relieve or reduce symptoms
reconstructive surgery
may follow curative surgery to re-establish function or for cosmetic effect
radiation therapy
use of high energy moving through space or medium to interrupt cellular growth, used to treat solid tumors

what is the main side effect of radiation therapy
bone marrow suppression that includes anemia, leukopenia, thrombocytopenia
what is a late sign of anemia
signs of thrombocytopenia
