Aww mama, I understand your worry, a few of us in our mum circle have dealt with cysts din, and it's scary talaga especially while breastfeeding! Good thing your doctor already cleared you na pwede pang mag-feed, kaya yan lang ang focus para sa ngayon. Honestly wala akong narinig na proven way na ma-dissolve siya through diet or supplements lang, so I'd really suggest asking your OB or a breast surgeon pa about your specific options, sometimes cysts shrink on their own, sometimes they need monitoring lang, pero it's best coming from your doctor na nakita na talaga yung 2-inch one. In the meantime, pag nag-express ka from the left para palakasin, mas maraming milk flow talaga ang makukuha mo, so keep going, you're doing great! Fingers crossed it resolves on its own, but don't hesitate to get a second opinion if you want more peace of mind.
