🙏Saying a prayer for you, your brother-in-law, sister, family, and friends. May God watch over and protect you. Many Anons posted good information below on potential cures. They are worth noting.

I have a family friend that recently cured a Stage 4 brain tumor with a combination of RSO & Apricot Seed powder (powerful anti-parasitic). I have read numerous medical studies that show the efficacy of antiparasitic medicine against cancer to include Ivermectin, Fenbenzadol, Mebenzadole, & Apricot Seed Powder. There are hundreds- literally hundreds- of clinical studies showing the efficacy of THC with RSO having the strongest and most potent anti-cancer activity. Additionally, Turkeytail mushrooms have also shown great results against breast cancer, but would likely be beneficial to a multitude of cancers. I hope your brother-in-law sees the wisdom in trying one or a multitude of these therapies-- especially since they can only help and will not harm. God bless you!🙏
