There are many types of health screenings that are recommended and just done in general. to me there are many more benefits than risks for most of these health screenings. They can help identify if you are at risk or even have any condition or disease you may not be aware of which could be life saving.  Early detection of these conditions or diseases will result in better management and treatment, which also in turn decreases the chance of complications and increases the chance of recovery or just better health outcomes in general. It is important to health screen so your body can have the best chance possible for treatment against conditions or diseases. If you have a family history that suggests you might be prone to certain conditions it is a good recommendation to get a health screening every so often. There are also age related health screenings that are done, for conditions that are prevalent in that age group. Overall, I believe health screenings are absolutely essential and helpful.
