Health screening is one of the most important preventive measures out there to control or prevent a lot of diseases. As a doctor, I have seen countless times when patients come to the hospital, it's always too late. There is very limited knowledge of health screening. Even if they know about the test but are completely unaware of the time to do so. I have compiled all the important health screening necessary for women based on their age group. The information is revised and up to date for the year 2020. The details here are reproduced from various important sources like the American Heart Association (AHA), the American Cancer Society, the United States Preventive Services Task (USPSTF) and the Center For Disease Control (CDC). It's time to take precaution, sooner the better.
