“Anticancer mechanisms of cannabinoids. Preparations of Cannabis sativa L. (marijuana) have been used for many centuries both medicinally and recreationally. Specifically, cannabinoids are well known to exert palliative effects in cancer patients. Their best-established use is the inhibition of chemotherapy-induced nausea and vomiting. Cannabinoids also inhibit pain. Therapeutic potential of canna
binoids in oncology might not be restricted to their aforementioned palliative actions. In addition to the well-known palliative effects of cannabinoids on some cancer-associated symptoms, a large body of evidence shows that these molecules can decrease tumour growth in animal models of cancer. In addition, cannabinoids inhibit angiogenesis and decrease metastasis in various tumour types in laboratory animals. Thus, numerous studies have provided evidence that thc and other cannabinoids exhibit antitumour effects in a wide array of animal models of cancer.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4791144/

If the product you are using contains methylparaben, ethylparaben, propylparaben, butylparaben and isobutylparaben, it has parabens. These ingredients are added to deodorants, toothpastes, shampoos, conditioners, body lotions and makeups, among other products, to stop the growth of fungus, bacteria and other potentially damaging microbes. Researchers have also found that some 90 percent of typical grocery items contain measurable amounts of parabens, which is why even those who steer clear of potentially harmful personal care products also carry parabens around in their bloodstreams.” https://www.scientificamerican.com/article/should-people-be-concerned-about-parabens-in-beauty-products/

“Cannabinoids reduce ErbB2-driven breast cancer progression through Akt inhibition. The therapeutic potential of cannabinoids, the active compounds of marijuana and their derivatives, has been known for centuries. During the last decade, evidence has accumulated suggesting that cannabinoids might be useful for the treatment of cancer. These compounds exert anti-proliferative, pro-apoptotic, anti-angiogenic, and anti-invasive effects in different cell-culture and animal models of cancer. Here, we used a genetically engineered animal model of ErbB2-driven metastatic breast cancer (the MMTV-neu mouse) to analyze the antitumoral potential of cannabinoids in this particularly aggressive pathology. Results presented herein (i) show that ErbB2-positive invasive human breast tumors express CB2 receptors, (ii) demonstrate that Δ9-tetrahydrocannabinol (THC) and the non-psychotropic CB2 cannabinoid receptor agonist JWH-133 significantly reduce tumor progression in a clinically relevant model of ErbB2-positive metastatic breast cancer, and (iii) shed light on the mechanism of cannabinoid antitumoral action in vivo. Taken together, these results provide a strong preclinical evidence for the use of cannabinoid-based therapies for the management of ErbB2-positive breast cancer.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2917429/

“Antitumor Activity of Plant Cannabinoids with Emphasis on the Effect of Cannabidiol on Human Breast Carcinoma. The therapeutic properties of the hemp plant, Cannabis sativa, have been known since antiquity. Δ9-Tetrahydrocannabinol (THC) exhibits antitumor effects on various cancer cell types. The aim of this study was to identify natural cannabinoids with antitumor activities at least similar to those of THC and devoid of the potential central effects of this compound. We found that, surprisingly, cannabidiol acted as a more potent inhibitor of cancer cell growth than THC and that cannabigerol and cannabichromene usually followed cannabidiol in the rank of potency. In conclusion, our data indicate that cannabidiol, and possibly Cannabis extracts enriched in this natural cannabinoid, represent a promising nonpsychoactive antineoplastic strategy. In particular, for a highly malignant human breast carcinoma cell line, we have shown here that cannabidiol and a cannabidiol-rich extract counteract cell growth both in vivo and in vitro as well as tumor metastasis in vivo.”

“Cannabidiol as a novel inhibitor of Id-1 gene expression in aggressive breast cancer cells. The helix-loop-helix protein Id-1, plays a crucial role during breast cancer progression. Reducing Id-1 expression could provide a rational therapeutic strategy for the treatment of aggressive human breast cancers. Cannabinoid agonists working through CB1 and CB2 receptors have been shown to act as tumor inhibitors in a variety of cancer models. In addition to Δ9-THC, CBD is also present in significant quantities in Cannabis sativa. Plant cannabinoids are stable compounds with low-toxicity profiles that are well tolerated by animals and humans during chronic administration. Our data presented here show that CBD represents the first exogenous agent that can down-regulate Id-1 expression in aggressive hormone-independent breast cancer cells. CBD represents the first nontoxic exogenous agent that can significantly decrease Id-1 expression in metastatic breast cancer cells leading to the down-regulation of tumor aggressiveness. Cannabinoids Reduce the Growth of Aggressive Human Breast Cancer Cells.” http://mct.aacrjournals.org/content/6/11/2921.full
“Pathways mediating the effects of cannabidiol on the reduction of breast cancer cell proliferation, invasion, and metastasis. We discovered that CBD was the first non-toxic plant-based agent that could down-regulate Id-1 expression in aggressive hormone-independent breast cancer cells. CBD has also been shown to inhibit breast cancer metastasis. Our data demonstrate the efficacy of CBD in pre-clinical models of breast cancer. The results have the potential to lead to the development of novel non-toxic compounds for the treatment of breast cancer metastasis. Treatment with CBD leads to the inhibition of Id-1 gene expression, proliferation, and invasion in mouse mammary cancer cells, and a reduction of primary tumor volume and number of metastatic foci in vivo. CBD, therefore, represents a potential non-toxic exogenous agent for the treatment of patients with metastatic breast cancer.”

“Cannabidiol Induces Programmed Cell Death in Breast Cancer Cells by Coordinating the Cross-talk between Apoptosis and Autophagy. Cannabidiol (CBD), a major nonpsychoactive constituent of cannabis, is considered an antineoplastic agent on the basis of its in vitro and in vivo activity against tumor cells. We found that CBD induced both apoptosis and autophagy in breast cancer cells. Characterizing more precisely the manner by which CBD kills breast cancer cells will help define the optimal applications of CBD as a cancer therapeutic. In summary, we showed that CBD, a plant-derived cannabinoid, preferentially kills breast cancer cells by inducing ER stress, inhibiting mTOR signaling, enhancing ROS generation, and mediating a complex balance between autophagy and mitochondria-mediated apoptosis in MDA-MB-231 breast cancer cells. These findings support the continued exploration of CBD as an alternative agent for breast cancer treatment.” http://mct.aacrjournals.org/content/10/7/1161.long
