My husband was diagnosed with Stage 4 HCC-Dec 2021. Check out Fraxini and Fraximus on the NIH website. Targets HCC. Available from Abnoba in Germany who manufactures it. Subcutaneous shots have brought tumor remission in 2 clinical studies. In Egypt they are doing IVs of Fraxini. Also Salicinium called Salicinomycin on NIH blocks metastasis by making the cancer visible to the immune system so Killer T cells and NK cells can target the cancer cells. Dr Warburg won a Nobel Price for this substance in 1931. Also read the Metabolic Approach to Cancer has lots of helpful information on how to turn on tumor suppressing genes.
