Whether the time of review can be advanced or not mainly depends on the items of review, some review items do not have hard time requirements, it is possible to advance the review; if the items of review have hard time requirements, it is recommended that the review is still due. The time of review can be selected according to the range of review time explained by doctors and nurses, choosing your own suitable time and cooperating with the disease treatment process. For example, the review of female sex hormones requires that they must be reviewed during the menstrual period, if the advance has not yet reached the menstrual period, there is no need for review. Another example is that female tumor indicators should be avoided during menstruation, if the menstruation is not yet over before the examination, it may lead to increased tumor indicator reactivity during menstruation, which affects the accuracy of the results. Another example is abnormal uterine bleeding, if the bleeding does not decrease after using medication, consult the doctor at any time, and there is no need to fix the time for follow-up. For specific cases, it is recommended to consult a specialized doctor.
