What are the differences between breast pain before menstruation and breast pain during pregnancy?

Patient's question:

No

Doctor's answer:

It is difficult to distinguish between premenstrual breast tenderness and pregnancy-related breast tenderness. I recommend you take a pregnancy test: it is the most important auxiliary examination for early pregnancy. Due to the secretion of human chorionic gonadotropin (hCG) by the trophoblast cells after pregnancy, this hormone can be measured in blood or urine using biological or radioimmunoassay methods to assist in pregnancy diagnosis. Previously used methods include the HCG spider test, latex agglutination test, and radioimmunoassay. Currently, the most widely used pregnancy test method is the colloidal gold-labeled antibody complex membrane-based sandwich immunoassay, which is the rapid early pregnancy test paper method.
