Yes, SOPC continues to have good success against brain cancers BUT I surely would not rely solely on SOPC, or any other single item for that matter, for any kind and stage of cancer. If it were me and I had late stage brain cancer, in addition to Oleander extract I would make sure to get some high THC cannabis oil no matter what it took, some highly bioavailable tumeric (such as the one from Nutrigold) and plenty of it and a top quality mushroom product such as Garden of Life's Immune Defense. All of those have had success against brain cancers and turmeric (whose major constituent is curcumin) also is a good natural anti-inflammatory. When it comes to brain cancers, inflammation is always a concern.

I hope this helps.
