Cytology: Diagnostic Principles and Clinical Correlates 5th edition PDF free download – The 20th century witnessed a remarkable decline in the mortality from cervical cancer in developed countries, an achievement attributable to the implementation of the Papanicolaou (Pap) test. In the 1930s, before Pap test screening was introduced, cervical cancer was the most common cause of cancer deaths in women in the United States.1 Today it is not even in the top 10, but it has not been eradicated; there are still approximately 13,000 new cases of cervical cancer in the United States each year, with 4000 deaths. Worldwide, cervical cancer incidence (over 500,000 cases annually) and mortality (over 300,000 deaths per year) rank fourth, after breast, lung, and colorectal cancers. Indeed, in some countries (e.g., those in sub-Saharan Africa), cervical cancer remains the most common type of cancer in women. Unfortunately, screening programs are rudimentary or nonexistent in many parts of the world: fewer than 5% of women in developing countries have ever had a Pap test.5 In contrast, 89% of women in the United States report having had a Pap test in the preceding 5 years.
