https://en.wikipedia.org/wiki/Cranberry
Cranberry juice is an abundant food source of proanthocyanidins and flavonols[27] and quercetin,[28][29] which are being studied in vitro.[30][31][32][33][34] However, their effectiveness in humans remains unknown, and is limited by poor absorption into cells and rapid excretion.

The extract from cranberry presscake was fractioned to obtain different extracts including a flavonoid rich extract. The different fractions were tested on different tumor cell lines. The flavonoid rich cranberry extract was the most active and inhibited the proliferation of many human tumor lines. The flavonoid rich cranberry extract was most effective against androgen-dependent prostate cells and least effective against estrogen-independent breast cells and androgen-independent prostate cells. Other cancer cell lines, including specific tumor lines of breast, skin, colon, lung and brain, showed intermediate reaction to the cranberry extract. Because the flavonoid rich cranberry extract had similar effect on estrogen-dependent M-C7 breast cells as well as estrogen-independent MDA-MB-435 breast cells the action of extract was not related to any anti-estrogenic action. It is not known which specific flavonoids are responsible for the inhibition of proliferation. Other studies have shown that the flavonoids epigallocatechin gallate(egcg), catechin and epicatechin. The flavonols quercetin, myricetin and resveratrol may also contribute to the anti-proliferation action of the cranberry extract.
