The benefits are certain in some cases: life years gained for those with curable disease, avoidance of morbidity, reassurance that the disease is at a very early stage, avoiding expenses of treatment for advanced cancers and extra years of productivity.

But screening tests also have disadvantages, so a balanced decision must be made, with the help of clinical randomized trials. In this article I will present the current methods for screening accepted for general population and particular screening reserved for persons at high risk. Although hpv virus and side effects the first case the benefit is proven, the use of these methods in practice varies largely due to lack of resources and well designed health programs.

Beneficiile sunt evidente în anumite cazuri: prelungirea su­pravieţuieii la cei cu hpv virus and side effects curabilă, scăderea morbidităţii, asigurarea pacientului că boala se află în stadiu incipient, evitarea costurilor crescute asociate cu tratamentul for­melor avansate de boală şi creşterea numărului de ani de productivitate.

Dar testele de screening au şi dezavantaje, aşa că un echilibru trebuie găsit, cea mai importantă con­tribuţie în acest sens fiind dată de testele clinice ran­do­mizate.

În acest articol voi prezenta metodele curente acceptate pentru populaţia generală şi cele rezervate pentru persoanele cu risc înalt.

New screening tests are under investigation: stool DNA hpv virus and side effects trials showed a high rate of false positivesvirtual colonoscopy and capsule endoscopy; they should not yet be used for screening. It had two arms: one used low dose helical CT and the other, standard chest X ray. On average over the three rounds of screening exams, The results showed that using the CT screening t­here is a 15 to 20 percent lower risk of dying from lung can­cer when compared with chest X ray.

The adenocarcinomas and squamous types hpv virus and side effects the most frequently detected, while small cell hpv virus and side effects cancer, known for its agresivity, was infrequently found on either CT or chest X ray Mammography This screening test for breast cancer has been shown to reduce mortality from the disease in women aged 40 to 74, especially in those aged 50 or older.

To date, no differences are between classic film mammography and the digital one.
