The prevalence of breast cancer has been acknowledged in the scientific community worldwide.
Breast cancer is widespread in women in Southeast Asia as a result of over 2 decades of economic prosperity caused by an unhealthy diet is a major concern.
The findings for effective treatments are ongoing with some successes, but the discovery of effective ingredients prevention and treatment of breast cancer with little or no side effects have proven difficult.
According to statistics, the risk of getting invasive breast cancer during the lifetime of a woman is 1/8.
Detection of tumorigenesis through self-observation is still the best approach to discovering breast cancer in the early stage.
But the reduction of the mortality at late stage discovered breast cancer has not been accounted for, even with extensively modern technology in the field of diagnosis and insurance protection in the Western world, needless to say of those countries with poor health care systems.
Suggestions of a healthy diet with plenty of vegetables and fruits(1)(2)(3) accompanied with a change of lifestyle (4)(5)(6) may be the only choice for women in reducing the risk of the disease.
In fact, certain vegetables(7)(8), fruits(9)(10), and bioactive phytochemicals found in foods(23)(24) and herbs(33)(34) have been found to induce apoptosis and anti-proliferation of breast cancer cells by blocking the energy sources to the tumor site and suppressing the promoted cancers genes.
1. Cruciferous vegetables
Cruciferous vegetables are a group of vegetable belongings to the family Brassicaceae, including cauliflower, cabbage, cress, bok choy, broccoli, etc.
Isothiocyanate (ITC), one of the major chemical constituents found in cruciferous vegetables has been studied extensively over the past three decades with evidence against breast cancer in preclinical models.
Benzyl isothiocyanate, the derivative of isothiocyanate displayed a significant efficacy in inhibited carcinogen metabolism and signaling pathways relevant to tumor progression and invasion(11) against MDA-MB-231(breast cancer cell line), human breast cancer xenografts(mutation tissues)(12) by suppressing X-linked inhibitor of apoptosis (XIAP) protein expression of cancer cell line MCF-7 and reduced levels of mutations of p53(antigens) protein level(13).
Loss of normal function of p53 gene was associated with over 50% of cancer patients and mutation p53 gene may have an oncogenic potential.
In Her-2 positive (a most aggressive case of breast cancer), indole-3-carbinol, a naturally occurring compound found in cruciferous vegetables, used combination with paclitaxel (a mitotic inhibitor) synergistically inhibited growth of Her2/neu human breast cancer cells by cancer cells cycle arrest in the G2(pre-mitotic phase) and M(nuclear division) phase and induced apoptosis/necrosis(14).
I3C used alone also inhibited Her-2breast cancer cell growth in a dose-dependent manner as the compound promoted the production of Bax(an apoptosis promoter) and decreased expression of Bcl-2(an apoptosis inhibitor) and, thereby, increased the ratio of Bax to Bcl-2 in favoring apoptosis(15).
2. Tomatoes
Tomato is red, edible fruit, genus Solanum, belongings to the family Solanaceae, native to South America. Because of its health benefits, tomato is grown worldwide for commercial purpose and often in a greenhouse.
Lycopene, a major carotenoid component of tomato has been known in the research community with the property to attenuate the risk of breast cancer.
In a time and dose-dependent, the compound showed an anti-proliferative activity against ER(estrogen receptor)/PR(progesterone receptor) positive MCF-7, HER2-positive SK-BR-3, and triple-negative MDA-MB-468 cell lines by arresting cell cycle at the G0 /G1phase(interphase together - chromosomes replicate in preparation for cell division) at physiologically achievable concentrations(range) found in human plasma(16)
Lycopene also Inhibited the ER-positive MCF-7 through cell cycle progression, and ER-negative MDA-MB-231 cells through G1 phase cell cycle arrest (17).
Application of lycopene not only restored the GSTP1 expression but also at 2 microM, once per week for 2 weeks induced demethylation of RARbeta2 (tumor suppressor gene) and the HIN-1(a cell growth inhibitor)) genes in the non cancer MCF10A fibrocystic breast cells(18).
3. Figs
N-hexane insoluble fraction (HIF) found in figs may be lesser known for its efficacy in breast cancer cell suppressive activity.
The combination of HIF and doxorubicin exerted a greater inhibition on cell growth in (Human ductal breast epithelial tumor cell line) T47D cells and increased the incidence of cells undergoing apoptosis, in compared to doxorubicin alone(19).
The soluble fraction (Ethyl acetate soluble fraction (EASF)) in Fig leave was also found to enhance the cytotoxic effect of doxorubicin by changing the inhibition of cell cycle G(2)/M to G(1) phase(20).
And Acetone extract of Ficus religosa leaf (FAE) demonstrated an irreversible inhibition of breast cancer cell growth with moderate toxicity by stimulating the loss of mitochondrial membrane potential in multiple breast cancer cell lines and accelerated cell death through the photosensitizing effect(21).
4. Garlic
Garlic is a natural superfood healer for its antibiotic antiviral, antifungal, anticoagulant, and antiseptic properties.
Diallyl trisulfide(DAS), a derived organosulfur compound (OSCs) suppressed the ratio of viable cells in the culture of (Human breast cancer cell line) MCF-7 and MCF-12a (a non-tumorigenic epithelial cell line) by decreasing the percent of cancer cells in phase G(2)/M and induced apoptotic cell death through a stimulated function of Bax protein and p53(cellular tumor antigen) protein expression(22).
The application of DAS also enhanced the effect of eicosapentaenoic acid, a breast cancer suppressor, and decreased the effect of linoleic acid, a breast cancer enhancer, and reduced the side effects caused by anti-cancer agents(23).
Protein fraction from garlic was effective in inhibiting tumor growth more efficiently than garlic extract in enhancing the CD8(+) T-cell infiltration into the tumor site(24).
5. Spinach
Spinach, an edible flowering plant in the genus Spinacia, belongings to the family of Amaranthaceae, is considered a healthy plant containing various vitamins and minerals, native to central and southwestern Asia.
Consuming spinach was found to exhibit a significant protective effect on breast cancer among premenopausal women(25).
Eating carrots or spinach more than twice weekly, compared with no intake, was associated with an odds ratio of 0.56 but did not distinguish among several potential explanations for the protective association observed between intake of carrots and spinach and risk of breast cancer.(26).
It is said that including supplementation of A. gangeticus aqueous extract of red spinach at 10% reduced the progression of breast cancer in rat models (27).
6. Kelp
Kelps are large seaweeds (algae) growing shallow in underwater oceans belongings to the class Phaeophyceae in the order Laminariales, used for food in many cultures.
Laminaria, a brown kelp seaweed containing antibiotic substance, 1-3 beta-glucan, was effective in activating a host-mediated immune response in preventing the initiation of breast cancer(28).
Japanese seaweed (Laminaria angustata) extracts were also found to exert antimutagenic effects in certain breast and colon carcinogens (29).
L-tryptophane substances isolated from the kelp rhizoid, may play an important role in the inhibition of breast cell proliferation(30)(31).
7. Chili pepper
Chili pepper is the fruit of a plant from the genus Capsicum, belongings to the nightshade family, Solanaceae, used in human history for spices and cultivated for commercial profits.
Capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide), a chemical constituent of chili peppers used in many cultures as an anti-cancer agent inhibited the growth of ER-positive (MCF-7, T47D, BT-474) and ER-negative (SKBR-3, MDA-MB231) breast cancer cell lines, reduced 50% the size of MDA-MB231 breast cancer tumors(32), through inducing cellular apoptosis via a caspase-independent pathway in MCF-7 cells(33).
In the comparison of Dohevanil, researchers found that both vanilloids, a precursor of capsaicin and dohevanil inhibited the growth of DNA fragmentation in MCF-7 cells(34).
8. Carrot
A carrot is a root vegetable with orange color normally, a subspecies of Daucus carota, belongings to the family Apiaceae, and native to Asia and Europe.
Intake of cruciferous vegetables and carrot are inversely associated with risk of estrogen receptor-negative/progesterone receptor-negative breast cancer(35).
Wild carrot or Daucus carota L. ssp. carota (Apiacea) oil extract, used in traditional medicine in Lebanon and different regions throughout the world was found to inhibit human colon (HT-29, Caco-2) and breast (MCF-7, MDA-MB-231) cancer cell lines, through apoptotic and anti-proliferative activities(36).
The information findings once again emphasized the importance of a healthy diet with plenty of vegetables and fruits and a change of lifestyle in breast cancer risk.
