Detecting cancer before the symptoms become distinguishable is what the cancer screening is having as its sole goal. Blood tests, urine tests and other tests, or even medical imaging are what this cancer screening might include. The advances of screening when it comes to cancer deterrence, premature detection and successive treatment should be weighed against any danger.

Screening could open a way to false negative results, where an existing cancer is missed. Aside from that, false positive results and ensuing persistent methods are two of what this cancer screening can direct to. When it is not clear if the benefits of screening outweigh the risks of the screening procedure itself, and any follow-up diagnostic tests and treatments, it is unavoidable for several issues to take place.

The screening which reaches everyone, often within a certain range of age is called or termed as universal screening, mass screening or population screening. On the other case, which is the case of the selective screening, it classifies the crowd who are noted to be at higher risk of growing a cancer, such as people with a family history of cancer.

During the times that the cancer screening was not yet acknowledged to be effective and actually saves lives, the screening for cancer has been widely controversial. Unless life expectancy is greater or more than five years and the benefits or advances are not sure for all, especially for those people over the age of 70, cancer screening will not be accepted.

Some of the common types of cancers usually screened are the breast cancer, cervical cancer, lung cancer, bowel cancer, and pancreatic cancer. Even though cancer is a serious matter but when discovered early, the chances of recovery is much higher as compared to a late stage. As such, routine health screening is very much encouraged regardless how healthy your body feels.
