Antitumor Activity

Royal jelly exhibited anti tumor activity in experimental mouse leukemias, and antiangiogenesis activity has also been demonstrated in vitro. In human cervico/uterine carcinoma cells, some royal jelly fractions actively inhibited tumor growth and some did not.

One study found that royal jelly inhibited the growth-promoting effect of bisphenol on breast cancer MCF-7 cell lines, although another study showed that royal jelly enhanced MCF-7 proliferation.
