であろう modifying a noun


In the book I'm reading I found this part:

>
> 原因がわからないので、治療もまだ暗中模索の状態であ病気悪くなるのを一時的に止める、あるいは悪くなるスピードを少しゆっきりにする効果のある薬が注目されているが、使われ始めてから日も浅く、長い目で見ていかねばならない。
>
>
> また、近年の目覚ましい遺伝子工学の発達で、遺伝性の場合には、病気を起こす遺伝子がどの染色体にのっているかを決め、病因となる遺伝子を健常な遺伝子に置き換えることが可能性となるのは時間の問題だが、この時起こる
> **であろう** 遺伝子操作の是非の理論に患者や家族など当事者の悲痛な声が充分に汲み取られることを望みたい

I think であろう is the volitional form of である, but I was unable to understand why
it's used there, and while I think I understand the general meaning of the
sentence, I don't understand the role であろう plays; I found some answer about
であろう, but nothing addressing this Vる + であろう + noun structure.

As far as I understand, the sentence means something like:

> I hope that in the theory of pros and cons of genetic manipulation which are
> occurring these days, the suffering voice of the people involved, like
> patients and their families, will be properly taken into account.

As context: the book is １リットルの涙, which is a diary of a girl sick with
spinocerebellar degeneration, which caused her to lose all her motor functions
as well as her capacity to speak, and in the end killed her. That sentence is
part of an afterword writter by her doctor.




であろう adds a sense of supposition, estimation, or guess: the speaker (or
writer) is not certain that this is the case, but is supposing or presuming
that it is.
