there are still many differences at the cellular level.

Who the heck cares? The tissue level is identical, what's important is that my receptors behave in a way that lets my breasts be breasts, and they do.

Well, tissues are made up of cells and if there are differences at the cellular level...

Histologically identical means identical at the tissue level. Saying there are cellular differences as some sort of gotcha is just really hurtful, it's not my fault I can't get change my DNA. If you define it based on that instead of its actual function, tissue and structure, you've missed the entire point which is that many secondary sex characteristics of our bodies are mutable and that there is nothing stopping someone from phenotypically changing sex.

I know what hitologically means, thank you. I was questioning your claim of not being histological differences because tissues are made up of cells. If there are differences at the cellular levels, those differences will manifest in the structure and function of tissues. And sex is not defined by secondary sex characteristics.

Then why do studies state histologically identical? Different cells could present the same tissue.

Studies are specific. The studies you cited were about what HCPs and scientists see when they use medical imaging to look at body parts. In the case of the papers you linked to, the imaging was of human breast tissue.

There are many, many studies done using microscopes to look at cells. There's vast numbers of studies and research papers on the ways cells behave. For example, the papers you cited were written to tell HCPs what tissue anomalies to look out for when reading breast scans. Whereas if you looked up breast cancer, you'd find a lot of papers about the behaviors of the cells in breast cancer.

If you search "human breast cancer" and "human breast cancer cells" you'll come up with different results. However, many research papers will deal with both tissues and cells because tissues are made of cells, and in cancer there is a problem with cellular growth and replication. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4929267/
