Biopsy not on lump

Hello

I had a biopsy today during my breast clinic appointment. The doctor did two, however both are about 1cm away from the lump - is this normal? It's only a small lump and I'm worried he did it in the wrong place - should it have gone in on the lump, or is it normal to do it from the side of the lump?

Sorry for the stupid question!
