Inhibiting a single
cancer cell development pathway with drug therapy can disrupt and may actually increase activity in other pathways and raise the risk of tumors becoming resistant to therapy.
Previous studies have also found that a compound called phenylethyl isothiocyanate (PEITC) in watercress may suppress
breast cancer cell development and prevent DNA damage in cells — just like broccoli sprouts.
Researchers are now studying the molecular mechanisms and signaling pathways
of cancer cell development, proliferation, and metastasis.
Strawberries and their major phytonutrient, quercetin, were also found to slow the normal cell cycle prior to cell death, suggesting that the protective actions may occur along different phases of
cancer cell development.
