I too have Ductal Invasive, ER+, PR+. HER2-, tumour 3cm, grade 3, and 1 node affected. Had mx and now on chemo, probably rads then 5 years of pill popping - I'm not going anywhere, and not even considering the death issue. It's far too early to worry about that yet. I'm going to be cured and enjoy the rest of my life. Try to focus on the positive, you have found it pretty early and it can be dealt with. When you have a treatment plan you will feel more in control and things WILL get easier, believe it or not. Sorry if I sound a bit short, but my last cycle of chemo has left me feeling a bit crappy, but I will be ok and get through this. Good luck and i hope your dog recovers so you can enjoy walks with her again soon.
