Short excerpt from a YouTube talk (Joy Kong, MD) warning that the source of stem cells matters: using a patient’s own cells means those cells carry their chronological age and accumulated genetic changes, toxins, or infections, which could increase the chance of promoting existing cancer—especially because aging weakens immune surveillance, and age is a major predictor of cancer.
Where the cells come from make a huge difference. Are we obtaining it from your own body, or are we getting it from somebody else's? Using your own cells, whether or not it's from fat or bone marrow, those cells will be your own age. So that comes with certain caveats. You have gone through your life, accumulated a lot of genetic changes. There could be toxins accumulating. There could be infections. And when you put these cells back into your body, there is a chance of promoting existing cancer. As we live our lives. Cancer cells is a normal physiological occurrence, Is part of life. But your immune system should be so strong. That it will just gobble them up as soon as they occur. But when you're aging, your immune system is less and less effective. That's when we see higher rate of cancer. That's why aging is the most predictive factor of cancer.
