An estimated 12,340 new cervical cancers and 4,030 cervical cancer deaths will occur in the United States in 2013. An additional 1,250,000 women will be diagnosed with precancers annually by cytology using the Papanicolaou (Pap) smear. A continuum of pathologic changes may be diagnosed, ranging from atypical squamous cells of undetermined significance to low-grade squamous intraepithelial lesions (LSIL) to high-grade squamous intraepithelial lesions (HSIL) to invasive cancer. The precancerous conditions LSIL and HSIL are also referred to as cervical intraepithelial neoplasia (CIN) 1, 2, and 3. Lesions can regress, persist, or progress to an invasive malignancy, with LSIL (CIN 1) more likely to regress spontaneously and HSIL (CIN 2/CIN 3) more likely to persist or progress. The average time for progression of CIN 3 to invasive cancer is estimated to be 10 to 15 years.
Caregiver assessment is done to find out if the caregiver needs support in the caregiving role.
Caregiver assessment helps the health care team understand the caregiver's everyday life, recognize the many jobs done by the caregiver, and look for signs of caregiver strain. Caregiver strain occurs when caregivers are not comfortable in their roles or feel they cannot handle everything they need to do. Caregiver strain may lead to depression and general psychological distress. If the caregiver feels...
The incidence of cervical cancer has decreased dramatically with the advent and widespread adoption of screening via gynecological examinations and Pap smears (refer to the PDQ summary on Cervical Cancer Screening for more information). Regular screening, however, is associated with large numbers of diagnostic procedures to evaluate abnormal tests, and the treatment of low-grade lesions may adversely affect subsequent fertility and pregnancy. Prevention of cancer may be more efficient, with fewer adverse consequences.
Nearly all cases of cervical cancer are associated with human papillomavirus (HPV) infection,[3,4] which is transmitted during sexual activity. Therefore, cervical cancer is seen more frequently in women with sexual activity at an early age and with multiple partners. Barrier contraception and/or spermicidal gels may offer some protection (refer to the Human Papillomavirus section of this summary for more information).
Cigarette smoking or exposure to environmental smoke is also associated with increased risk among HPV-infected women, suggesting that components of tobacco are promoters of abnormal growth of viral-infected cells.
