I lost my brother to cancer 3 years ago. During his last months, I did quite a bit of research into CBD oil and how it works on cancer. Please correct me if I am incorrect. What I gathered is that cancer cells each have a lifespan. CBD oil retards reproduction of cancer cells. As a result, over time, more cancer cells will die off than new cells being produced. This results in the cancer shrinking and hopefully dying off. Unfortunately my brother and his family could not be convinced to try it because of state laws at that time.

@binky957 -- Good morning and welcome to Mayo Connect. I am so sorry for the loss of your brother. It must have been very painful to have watched his decline. Unfortunately at this time there is no proof that CBD oil or any cannabis product kills cancer cells. Even if it will prove to be true that these products can kill cans cells people with cancer do not have the luxury of time. Some cancer cells reproduce at a very high rate, that's why some people die so quickly. If cancer cells can be killed off faster by any substance then that's a gold mine!

I hope that this helps to understand this horrible disease better.
