Barriers to Pap testing in developing countries are substantial and include lack of public health and medical infrastructure to organize population screening and follow-up, as well as the high level of expertize and quality control needed to ensure accuracy of cytologic diagnosis.
During organ formation, cells proliferate, migrate, and invade into adjacent tissues to produce highly organized tissues, and these same cellular processes are used during carcinogenesis, which results in the formation of relatively organized populations of abnormal cells, which comprise tumors.
Thus, this spatially organized population of TGFβ receptors is slower and more confined, possibly due to interactions with other proteins.
Delays can be reduced by increasing BC awareness, implementing organized population-based screening programmes and founding cancer centres.
The first and continuing organized population-based screening programme started in 2008 in Bahcesehir County, Istanbul and included >10,000 women aged 40 69 years.
Certainly, tissues are not just a loose accumulation of individual cells, but a highly organized population of interacting cells.
Whether such a reduction occurs in a long-running, organized, population-based breast screening programme is what Joost Nederend and colleagues explore in their study from The Netherlands [ 1].
Understanding the burden of hypertension, as a preventable disease, and underlying risk factors by organizing population screening is the first step towards planning any effective preventive programs.
In order to address low adherence to screening guidelines, Ontario's Ministry of Health and Long Term Care launched an organized population-based colorectal cancer screening program called ColonCancerCheck in March of 2008 [ 23].
Despite evidence of its effectiveness, organized population screening for colorectal cancer has only been implemented on a national scale in France, the United Kingdom, Finland and northen Italy [ 8, 11].
