“cannabidiol, (CBD), has the ability to “turn off” a gene that causes breast and other types of cancers to metastasize, according to the San Francisco Chronicle newspaper.
“What they found is that the cannabinoid turns off the overexpression of ID-1, which makes the cells lose their ability to travel to distant tissues. In other words, it keeps the cells more local and blocks their ability to metastasize. (spread to a new location) The researchers stressed cannabidiol works only on cancer cells that have these high levels of ID-1 and these do not include all cancerous tumors but, rather, aggressive, metastatic cells. But they’ve found such high levels in leukemia, colorectal, pancreatic, lung, ovarian, brain and other cancers.””
