Breast asymmetry occurs when one breast has a different size, volume, position, or form from the other. Breast asymmetry is normal, and almost every woman's breasts are not exactly the same on both sides. Poland's syndrome is a very rare condition where the chest muscles are missing or underdeveloped on one side and the breast is also much smaller. This can happen in women or men. In general, this is all normal. If asymmetry occurs rapidly and one breast becomes much smaller or larger over a short period of time this should be evaluated by a physician.
Seek professional care if you experience any of the following symptoms

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
