Oh so annoying on the nodes but do know that many many women on here have gone back for exactly what you have to go for. We all wait with baited breath if enough sentinal nodes were negative to not have more. But alas for many it's not the case. My niece at 32 had 20 nodes removed and 10 were positive. (Yet her original lump was less than 2mm....yes less than 2mm) 15 years on she remains cancer free.
Do you know what type of bc you have yet?
Oh it's a hard journey and I so hope things are done with for you soon. Kath x
