DOES THC and CBD REALLY FIGHT CANCER
THE POWER OF NATURE
Cannabinoids have anti-tumor effects by decreasing the viability, proliferation, adhesion, and migration of various cancer cells, making them an ideal cancer treatment.

Medical cannabis specifically targets tumor cells but has low potency for non-tumor cells compared to traditional chemotherapy which cytotoxicity affects tumor and non-tumor cells a like.

In breast cancer, THC inhibits overall cell growth and proliferation.

THC inhibits estradiol-induced cell proliferation by inhibiting estrogen receptor α activation.
https://pubmed.ncbi.nlm.nih.gov/18249480/
THC inhibits breast cancer proliferation at the G2/M phase via CB2 due to the downregulation of cell division control (Cdc2) which in turn induces apoptosis.

https://pubmed.ncbi.nlm.nih.gov/16818634/
In vivo, THC reduces ErbB2-driven metastatic breast cancer growth and reduces metastasis to the lung.

THC inhibits the heterodimerizations of HER2 and CB2 preventing the tumorigenesis of breast cancer in vitro and vivo.

Furthermore, in vivo THC significantly reduces tumor growth and decreased the expression of the HER2 protein.

Effects of CBD in vitro and in vivo in breast cancer.
https://pubmed.ncbi.nlm.nih.gov/32708138/
CBD induces apoptosis and autophagy via reactive oxygen species (ROS) production causing endoplasmic reticulum stress apoptosis in select breast cancer cells.
https://pubmed.ncbi.nlm.nih.gov/21566064/
CBD inhibits epidermal growth factor (EGF)-induced proliferation, migration, and invasion of breast cancer cells.
https://pubmed.ncbi.nlm.nih.gov/25660577/
CBD significantly reduces migration, invasion, and expression of malignant markers as well as promotes the recovery of cell contacts in 6D, the invasive mesenchymal-like phenotype in MCF-7, breast cancer cells.
https://pubmed.ncbi.nlm.nih.gov/32244518/
CBD also increases sensitivity to anti-cancer drugs doxorubicin and cisplatin in 6D cells by downregulating the expression of resistance proteins.

CBD also increases sensitivity to anti-cancer drugs doxorubicin and cisplatin in 6D cells by downregulating the expression of resistance proteins.https://pubmed.ncbi.nlm.nih.gov/32244518/
CBD reduces advanced-stage breast cancer metastasis via the downregulation of the Inhibitor of DNA binding protein 1 (Id1), a transcriptional factor and marker for breast cancer cell metastasis to the lung.
https://pubmed.ncbi.nlm.nih.gov/24910342/
CBD also reduces the proliferation and invasion of breast cancer cells by reducing the expression of Id-147
https://pubmed.ncbi.nlm.nih.gov/16078104/
Endocannabinoids have also inhibited the growth of PC3 prostate cancer cells via inhibiting adenylate cyclase and protein kinase A activity, arresting the cell cycle via the induction of p27 and downregulation of the EGF receptor.
https://pubmed.ncbi.nlm.nih.gov/32872551/
https://pubmed.ncbi.nlm.nih.gov/25606819/
Endocannabinoids have inhibited the growth and induces apoptosis in primary prostate tumors via activation of the ERK signaling pathway.
https://pubmed.ncbi.nlm.nih.gov/32872551/
https://pubmed.ncbi.nlm.nih.gov/25606819/
Phytocannabinoids THC and CBD have been shown to reduce prostate cancer cell viability by inducing apoptosis.
https://pubmed.ncbi.nlm.nih.gov/22594963/
THC induces apoptosis in a dose-dependent and cannabinoid receptor-independent manner in prostate cancer cells.
https://pubmed.ncbi.nlm.nih.gov/10570948/
CBD inhibits prostate cancer cell growth via the induction of intrinsic pathways of apoptosis, cell cycle arrest at the G1-S phase, and activation of p53 and elevated ROS levels.
https://pubmed.ncbi.nlm.nih.gov/22594963/
CBD when used in combination with anti-cancer drugs, Docetaxel and Bicalutamide, can effectively inhibit tumor growth in vivo and vitro.

Conclusion
Cannabinoids employ anti-tumorigenic effects on various tumor types. Cannabinoids have been proven to be tumor suppressors affecting proliferation, migration, and invasion inducing apoptosis and autophagy. Cannabinoids also regulate vital processes that are essential physiologically and biologically such as cell homeostasis, cell motility, inflammation, pain-sensation, mood, and memory.
These data support the clinical testing of CBD against prostate carcinoma.
