Yes, very understandable. I would worry too. These are such difficult decisions! I actually had 3 lumps in my right breast, and one in my left. The biggest was grade 1, the others were grade 2. The fact it was both multifocal and bilateral made me worry too,
and think seriously about having the chemo. I did ask my onc if that made things worse and he said no. The main reason chemo was suggested was cos of my age.
But your lump was bigger. However, despite its size, you still had no node involvement. So I think it probably was just sitting there for a while, growing slowly and minding its own business. My onc compared my biggest tumour to a cocker spaniel, and the others to a Jack Russel (tiny node involvement). Yours sounds like my cocker spaniel, not aggressive at all. However, ca is ca, and if you have the funds, maybe you should do the test. I have read comments of a couple ladies though, who did the oncotype, only to still get inconclusive results and still be told it was a grey area. Another lady (@Dory65 ?) did it, and it came back she didn’t need chemo. Same ca type as ours I think.
This bc business ain’t fun 😕.
Good luck with your decision ♥️
