Over the recent years the word has been changing rapidly due to the recent developments in technology and much more advancements. This definitely comes with various merits and demerits that lead to various issues that ought to be controlled every now and then. The modern day foods and chemical substances have led to the emergence of various diseases that are of a major concern to the health of human beings. Cancer for example is a dangerous disease that is killing millions of people day in day out. However, this can be effectively controlled by early identification through the body screening process.

Modern technology has enabled the manufacture of machines that can enhance the effectiveness of this process. The computed tomography (CT) for example is one of the technologies used to carry out a full body scan on a person. This scan forms a part of the diagnosis or the treatment of the illness identified. With the screening from different angles and depths, the doctors are able to compile an image that can be assessed for any abnormalities.

These scans are very beneficial generally to the health problems. When these abnormalities are detected at an early stage the doctors can be able to enforce curative measures on the patient to control the situation. Performing the tests on persons who do not have the signs of any illness however becomes a problem at times. It therefore requires that risks associated with this be compared to the benefits from the process well.

In the general process of carrying out this testing, risks are a major concern to be considered because they are part and parcel of the process. However, risks differ with regard to the method of testing being used. Some methods are more harmful than others. With the knowledge of all this potential risks, the investigation on the volubility of this process should be grounded upon adequate proof.

These risks are of various types. The major one of them all is that a patient is exposed to very high radiations. This exposure may be as a result of a very small increase in cancer which is not proportional to this amount of radiation exposure. Too much exposure of the radiations may result in some health problems to the patient in the long-run. Some technologies such as the magnetic resonance imaging have some magnetic field that can heat up metallic implants causing the soft-tissue tears or burning.

Whenever these processes are carried out, they do not give complete specificity or sensitivity. This can lead to the derivation of false positives or negatives which are henceforth not beneficial for the process. The highly specialized machines for the process are expensive hence making the whole process expensive.

Due to the scrutiny a person gets exposed to, this process has been adopted for security checks. Methods of committing crime have been diversified thus this method proves appropriate. Drug traffickers can now be netted easily in case the drugs are hidden within their body system.

It is evident that body screening has several demerits and it poses several health issues of concern, however the benefits outweigh this. It is recommendable to have the screening to control health issues. This will also enhance security and safety worldwide.
