Hi @JoeyLiz. I'm not sure of what your time frame was, but tumours don't usually grow overnight, so to speak, and as you would know. It kind of makes sense to me, that a growing tumour may well have impacted on milk flow. Because she was fussy at that breast, she probably spent less time there. Less time stimulating that side would lead to a lower supply, which then becomes a cycle.
Now just theorising, but I would also wonder if a developing tumour would have any impact on taste. The taste of breast milk alters subtly depending on what a woman eats, which they say then leads to a breast fed baby accepting the new flavours of solids more readily. Not gospel, but something I've read & heard about.
Hope you're travelling ok
