I have lumpy breast tissue anyway as I'm very flat chested. I have a lump of fibrous feeling tissue in my right chest. It's oblong shapes and quite big. It does move when you push it. I first discovered it last April but my mum does soon after and it was put to the back of my mind. Rediscovered it today and it feels much the same. I hope that's a good sign but I'm back to freaking out. I'm under 30. This probably won't be cancer will it? If it is I'm stuffed leaving it for so long.
