What needs to be reminded is that if you do not fill in the form truthfully when you apply for insurance, the insurance company may judge that you have not fulfilled your obligation to inform based on other information in the future. According to my experience, if your illness is an unspeakable disease, it should have little impact on your health after recovery. If you are really worried, you can go to the hospital for a routine physical examination first. If there is no problem, you can rest assured to insure.
