These amino acids are normally found in the human body. To the best
of my knowledge, there is no causal link to
Copaxone causing cancer. There are a certain number of patients that develop cancer and report it while taking Copaxone, but I believe that is statistically equivalent to the incidence of cancer in the general population. Because it was reported, it will be listed in the prescribing information, but that does not mean that Copaxone causes cancer.
