CANNABIS E CANCRO

Su questo argomento si leggono molti pareri ed esperienze personali. Il paziente che fosse interessato ad approfondire il tema, entra da subito in confusione perché su web può trovare di tutto ed il contrario di tutto.

Cito questo lavoro scientifico pubblicato nel mese di giugno 2015, su una autorevole rivista, redatto da due autori che hanno dedicato la loro attività di ricerca alla Cannabis nella cura del cancro.

Come si legge, le prospettive sono incoraggianti, ma molta strada deve essere ancora percorsa, perché gli studi fatti fino ad oggi sono su cellule tumorali coltivate in vitro o su animali.

CANNABINOIDS AS ANTICANCER AGENTS

….Cannabinoids may exert their antitumor effects by a number of different mechanisms, including direct induction of transformed cell death, direct inhibition of transformed-cell growth, and inhibition of tumor angiogenesis and metastasis….Despite these impressive in vitro and animal model findings regarding the potential antitumor effects of cannabinoids, there is still no solid basis for ongoing claims by proponents of highly concentrated cannabis extracts or oils that these preparations can “cure cancer.”…… Although the in vitro and animal evidence is intriguing, there have not yet been any robust human studies

investigating cannabis as an anticancer agent that would warrant advising patients to forego conventional therapy in favor of using a high-potency cannabis extract. Patients who choose to delay conventional therapies in the hopes of benefiting from a trial of cannabis oil against their cancer risk the possibility of having a potentially treatable cancer become incurable. As the preclinical evidence suggests that cannabinoids might enhance the antitumor activity of conventional chemotherapeutic agents as well as ameliorate

associated side effects, the addition of cannabinoid-based preparations to standard cancer therapy should not be discouraged by the treating oncologist.
