Metaplasia
abnormal change in nature of tissue. reversible, benign. Squamous metaplasia - the process of change from columnar to squamous cells
Dysplasia
pre-cancerous condition, detected by pap test. 100% curable. usually causes no symptoms.
Hyperplasia
increase in reproduction in cells (excess tissue growth) often initial stage in development of cancer
Transformation Zone
area between old and new SCJ. Take cells for pap test. HPV causes cervical cancer here and most abnormalities are thought to arise here.
CIN
Cervical Intraepithelial Neoplasia - aka cervical dysplasia development of abnormal cells in narrow neck of uterus (cervix), cell changes, pre-cancerous primarily caused by high risk HPV, not always.
Endocervix
Opening of uterus, tissue surrounding the endocervical canal (connects vagina to uterus)
Exocervix
portion of uterine cervix extending into vagina and lined with stratified squamous epithelium
Squamocolumnar junction
Sample this in pap test, where uterine cervix meets, has abrupt change in cell types
Neoplasia
abnormal proliferation of benign or malignant cells. primary cause is HPV
Interferon
Most common drug therapy for cervical cancer. Sometimes combined with chemotherapy. Side effects: flu-like symptoms, rash, anorexia, bruising.
Amenorrhea
Primary: menstruation never occurs
Secondary: absence of menses for 3 months
Adenocarcinoma
Rare vaginal cancer. Usually occurs in women over 50. Asymptomatic or abnormal vaginal bleeding. Tx: surgery, radiation.
Squamous
very thin, flattened scaly tissue
Epithelium
thin tissue forming the outer layer of a body’s surface
Opportunistic infection
Infection caused by pathogens that take advantage of an opportunity not normally available such as weakened immune system or change in normal flora, pneumocystitis carnii pneumonia is most common
