In addition to shifting to a low-fat vegan or quasi-vegan diet, many patients also begin taking special nutrients and phytochemicals that are naturally derived from plants. Those employed within cell signal transduction therapy include green tea extract and milk thistle extract, as well as fish oil-derived omega-3 fatty acids. Patients may also begin a regimen that includes salsalate, diclofenac, boswellic acids, and disulfiram.
Taken together, a properly planned supplement regimen can boost under-active pathways and help in the suppression of signal transduction pathways that are overly active in cancer cells. The ultimate effect is to starve cancer cells of their capacity to grow and spread into diffuse organs, as well as inhibit cancer cells from creating new blood vessels that serve to nourish the tumors.
