But screening tests also have disadvantages, so a balanced decision hiv and lung cancer 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 familial cancer syndromes list risk.
Although in the first familial cancer syndromes list the familial cancer syndromes list is proven, the use of these methods in practice varies largely familial cancer syndromes list to lack of resources familial cancer syndromes list well designed health programs.

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.
Cancer prevention through screening programs
În acest articol voi prezenta metodele curente acceptate pentru populaţia generală şi cele rezervate pentru persoanele cu risc înalt. Deşi în primul caz beneficiile sunt dovedite, utilizarea lor în practică variază larg din cauza lipsei de resurse şi a lipsei implementării programelor de sănătate publică.

It also applies to advanced disease which is asymptomatic or without complications at time being. The fourth level of prevention - according to some authors, could be considered prevention of suffering from side effects of treatment and complications, pain and maintaining the quality of life of the patients 4. Screening can be familial cancer syndromes list for a certain cancer in the following situations: if it is frequent, has a long preclinical evolution, is associated with increased mortality and morbidity, long preclinical non-metastasis faze and if early detection offers access to treatment that improves outcomes.
It is important to remind that screening tests can have potential harms as well as benefits. Some screening tests may have side effects, cause discomfort or severe complications. Screening tests can have false-positive results.
This type of cancer has a high mortality, and the overall survival is also low. In these conditions, researchers are always looking for improving the therapy. In this presentation, we mention the histological types of pancreatic cancer, the importance of systemic therapy for operable cases pre- and post-surgeryand of chemotherapy for advanced and metastatic cancer. New therapeutic agents have been introduced, that appear to give new hope for a more efficient treatment. Acest cancer are o mortalitate ridicată, iar supravieţuirea globală este de asemenea scăzută.
