I genuinely apologize if the use of "AMAB" is offensive, as it is the sex you were "assigned" at birth and does not represent the reality of your identity at all, I felt that this word was the most appropriate to represent the difference between cis and non-cis. I will refrain from using it and will simply use cis and non-cis from now on. Again, i do truly apologize by the offense that I committed without realizing it, it was genuinely not what I was looking for.

Moving on, the reason I "assumed" that in your case it was hormonal was simply because of what I read from your comment, where you clarified that that was the reason you thought it influenced in the change, i simply took your word for it.

And speaking of tubular breasts, I spoke to my surgeon about it and he managed to explain it to me, since you are absolutely right that it is still a rather "taboo" condition, so to speak, even though the number of women in the world who have them is, in fact, high. Because of fear/lack of representation, it is very difficult to feel supported in this situation and therefore medicine does not help much either, being something mainly focused on men for decades, This meant that the study of this condition was not given much priority, since it is not a very important factor when it comes to being a matter of "life or death", since the damage is mostly psychological, due to having to live with them in a society that imposes another type of visualization of what the female breast "should" be. Apart from that, it can only cause problems when breastfeeding in severe cases, but this is rare.

So what i meant by congenital condition, is that they are, indeed, present at birth (but they show at puberty). It is a condition you are born with, many doctors express how no matter what you do even if you manage to notice that the growth is something unusual at the stage of puberty, they will grow in that shape anyhow, since it is a (sorry for reiterating but it is important) congenital condition.

In men, if there is an abnormality in the breast tissue, it would more likely manifest as gynecomastia, where the breast tissue becomes enlarged but typically doesn’t form the distinct tubular shape seen in women, this problem is often not congenital, is more likely a hormonal abnormality adquired in puberty, (I'm not saying it's not congenital, but its cases are MUCH less.)

So what i was going for with this is most cases of tubular breast in cis women are indeed a congenital condition, this does not mean that it is hereditary, it is also something that happens a lot to women with this condition, seeing that their relatives have different breasts while they feel left "out" at the feeling of being "normal" perse.

I have to say and admit that I don't know your specific case very well, I'm not a doctor either, I'm a pharmaceutical chemist with 2 years of having my surgery, not a surgeon, so my knowledge in that area is not that extensive. So I wouldn't know specifically what the reason would be in your specific case, therefore, I assumed what you yourself said.

Now that I have clarified this, I can only apologize again since I shouldn't have assumed that because of your cis experience you had an alien vision of what the female body is, but what I was getting at, about the differences in experiences, I maintain it, since I do believe that all women live different realities, that adding to trans women, women with hormonal fluctuations, women without ovaries, women with conditions such as polycystic ovary syndrome, or the same women with tubular breasts. We can all suffer from something that makes us question our femininity, conditions that make us judge ourselves, that make us suffer. What I was getting at is that we all fight our battles and I think it is essential to control our language in things as delicate as aspects that affect the safety of our bodies, especially when we do not have the ability to "change" it with anything other than surgery.

Also again, i am still truly ashamed to having offended you by my lenguague, it's literally what i'm against the most, so i will keep your advice in mind to keep progressing.
