The benefits are certain in some cases: life years gained for those with familial cancer syndromes list disease, familial cancer syndromes list 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 in the first case the benefit is proven, the use of these methods in familial cancer syndromes list varies largely due to lack of resources and well designed health programs. Beneficiile sunt evidente în anumite cazuri: prelungirea supravieţuieii la cei cu boală 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.
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. Checking for familial cancer syndromes list or for conditions that may become cancer in people who familial cancer syndromes list no symptoms is called screening.

It is usually assimilated with secondary prevention and involves the use of diagnostic tests in an apparently healthy population. Many people wrongly mistake screening for prevention 2.
There are several forms of prevention: Primary prevention - aims to prevent disease before it ever occurs. This is done by preventing exposures to hazards that cause the disease, altering unhealthy or unsafe behaviors that can lead to disease, and increasing resistance to disease if exposure occurs.
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.
One example is vaccination 3. Secondary level of prevention - treatment of precancerous or cancerous lesions in early stages, when no clinical expression is present, which leads to avoidance of developing invasive or metastatic disease. It includes screening asymptomatic patient familial cancer syndromes list early detection diagnose in phase of minimal symptoms of disease. 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 proposed for a certain familial cancer syndromes list 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 familial cancer syndromes list 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. Screening tests can have false-negative results.
Overdiagnosis is possible. This happens when familial cancer syndromes list screening test correctly shows that a person has cancer, but the cancer is slow growing and would not have harmed that person in his or her lifetime.

This can lead to overtreatment 5. Screening tests that have been shown to familial cancer syndromes list cancer deaths Colonoscopy, sigmoidoscopy, and fecal occult blood tests FOBTs Colon cancer is the third most frequent cancer in both men and women. Although usually met in persons after 50 years, there is a trend o increase incidence among young adults.
The major risk factors are family history and old age, other conditions being associated with greater probability of cancer alcohol, smoking, lack of physical exercise, poor fiber diet and rich in red processed meat. Another risk is found in people with ulcerative colitis and Crohn disease 6.
Genetic consult, thorough history till second degree relatives familial cancer syndromes list IHC imunohistochemical and genetic testing should be considered in those with HNPCC hereditary nonpolyposis colorectal cancer familial cancer syndromes list like in Lynch syndrome with its variant - Turcot patients with MMR - mismatch repair gene mutations and brain tumoursand Muir-Torre syndrome MTS - cutaneous gland tumours like keratoacanthomas and sebaceous tumors zinc dysbiosis with colon, breast, and genitourinary tract neoplasia.
Guaiac FOBT: is used to detect a part of the blood protein hemoglobin. It requires avoidance of certain food before testing red meat. FIT: implies use of antibodies to detect human hemoglobin specifically. No dietary restrictions are needed. Studies suggest testing every year beginning with the age of 50 until 80 years; it helps reduce death from CCR by up to 33 familial cancer syndromes list 8,9.
Sigmoidoscopy has the advantage of visualizing the rectum and sigmoid colon and being able to biopsy suspect lesions. Preparation for the test is less demanding than that wart on foot under skin for colonoscopy.
Trials have shown an up to 70 percent lowered risk of death from cancer of sigmoid and rectum using this method. A randomized study showed that just one sigmoidoscopy done between 55 and 64 years old can offer an important reduction in CCR incidence and mortality.

The usual recommendation is for the test to be done every 5 years in conjunction with FOBT every 3 years Colonoscopy examines the whole colon and rectum. A form of sedation is recommended for familial cancer syndromes list comfort.
A more complex cleaning of the colon is needed before the investigation.
