1- Are the treatments with stem cells safe?
There is no medical procedure that does not involve any risk. Clinical trials are necessary to verify that the beneficial effects of a treatment outweigh these risks. If the cells that are injected have been cultivated, they may have lost control mechanisms of their proliferation, and there is a risk of generating tumors. In these cases, tests must be performed to confirm their genetic stability. Other risks are those of infection, immune rejection or complications derived from the medical process. Before participating in a treatment, it is necessary to have guarantees that all these risks have been considered and prevented as far as possible, and that there are means to treat potential side effects that may arise.
