In this brief commentary, surgeon Patrick Denard warns that peptide therapies, such as BPC-157, can stimulate angiogenesis (neo‑angiogenesis). Because angiogenesis can feed existing tumors, using peptides without prior medical evaluation could inadvertently promote cancer growth. Denard advises that anyone considering peptide use should undergo thorough cancer screening beforehand to avoid stimulating a hidden malignancy.

For instance, if you look at cancer, that is stimulated blood cell projection or angiogenesis, neoangiogenesis. So if somebody were to have an underlying cancer, you would by no means want to be stimulating that process to occur. So one of the things that along those lines it's important to do anytime somebody considers peptides, in my view, is to really seriously consider should you do any screening in advance.
