Before any symptoms of a person, cancer screening is looking for cancer.
Screening test can help the cancer appear in the early stages, before symptoms. When abnormal tissue or cancer is found early, it can be easy to treat or treat it. Signs of time appear, cancer can increase and spread. It can make cancer difficult to treat or cure.

It is important to remember that when your doctor suggests a screening test, it does not always mean that they think that you have cancer. Screening is done when you do not have cancer symptoms

There are different types of screening tests

The screening test includes:

• Physical examination and history: An examination of the body in order to examine the general symptoms of health, including examining the symptoms of diseases, such as lump or something that looks unusual, patient health habits and previous illnesses and remedies. A history will also be taken.
• Laboratory tests: Medical procedures that test the body's body tissue, blood, urine or other substances.
• Imaging procedures: processes that make pictures of areas within the body.
• Genetic testing: Tests that are for some mutations (changes) that are linked to certain types of cancer.

There is risk in screening tests.

Not all screening tests are helpful, and most are risk. It is important to know that the risk of testing and whether it has been proven to reduce the chances of cancer death.

Some screening tests can cause serious problems.

Some screening procedures may cause bleeding or other problems. For example, screening of colon cancer, sigmodoscopy or colonoscopy can cause tears in the lining of the colon.

False-positive test results are possible.

The results of the screening test may be revealed even after being abnormal, although there is no cancer. A false positives test result (which shows that when cancer does not happen in fact, cancer happens) can cause anxiety and generally there are more tests and procedures, including risk.

False-negative test results are possible.

Although the results of the screening test may be normal, although cancer is there. A person who receives false-negative examination results (which shows that there is actually no cancer) can delay looking for medical care, even if there is a symptom.

The detection of cancer does not improve the health of the person or it can help the person to stay for a long time.

Some cancers cause no symptoms or life threatens, but if found through a screening test then cancer can be treated. There is no way to know that treating cancer will help the person to stay for a long time if no treatment was given. In both adolescence and adults, after the diagnosis of cancer, the risk of suicide increases in the first year. In addition, there are side effects of cancer treatment.

For some cancers, detection of cancer and its treatment does not improve the chances of treatment quickly or helps the person to stay for a long time.
