8 months postpartum

Found hard small lump on the inside of my right breast, been referred to clinic waiting on appointment,  got slight breast discomfort in both breasts but comes and goes.

I'm 8 months post partum and I'm so worried it's going to be cancer,  I've cried so many times thinking worse case not been able see my girls grow up.

Anyone had simular symptoms or position of lump amd had positive news
