Hi June and all
"You learn something new every day" seems to be my motto lately. So, because
I had only basic knowledge about this I went looking.
Might be worth checking with her surgeon - adenectomy refers to removal of a
tumor, hypophysectomy refers to the removal of the pituitary gland.
I found out pituitary tumours are usually benign, called adenomas. If
malignant, which is very rare, they are called pituitary carcinomas. I found
out that there are two types of tumours - secretory that make more of a
hormone (and it carries this name eg prolactin tumour) and non-secretory.
From this I understand that if the tumour ONLY or part of the pituitary
gland has been removed then the pituitary gland can return to normal or
possibly lower levels of prolactin production so initiation of breastfeeding
is possible. If the whole gland has been removed she would be taking hormone
replacement therapy but this does not include prolactin - studies on animals
are occuring and research is also hypothisising that prolactin has more
essential functions in the human body than related to lactation.
Strangely I also found out that some tumours when removed actually reduce
access of the dopamine compound into the ptuitary gland from the
hypothalamus (which puts a brake on prolactin production) so prolactin
secretion increases. Weird!!!! So her supply may actually be more than
adequate.
If anyone can correct me or add anything ot this I would be grateful........
regards
Del
