This post is probably going to get me in trouble with some people, or maybe I am crazy.  WRT the lump under the nipple as a start to budding for breast development, I have never felt such a breast  tissue structure on an older cis woman's breast.  My sampling is low, maybe about 100 women in their 20's thur 60's. For me, I have found only soft tissue in that region of a cis woman's breast.  Maybe the tissue lump under the nipple is a developmental feature of a new breast that goes away after the breast has developed?  Maybe its something that happens to young women who are entering puberty?

100 women? I am impressed! But as for the lump, I had lumps behind my nipples when I reached puberty, and they were hypersensitive, but they gradually disappeared.  My understanding is that the tissue constituting these lumps gradually fuses into the developing breast. FWIW I developed gynecomastia at puberty, and my nipples were and have remained highly erogenous.
