The doctor, who has not treated Anderson, added that the type of aggressive anti-viral drug used to treat the 90s bombshell's hepatitis has also allegedly been known to trigger an alarming increase in deadly cancers.
'These are powerful anti-viral medications, and she may have developed serious side effects that range from nausea to vomiting to the emergence of caner,' he told the publication.
'I have personally seen people treated for hepatitis C who have developed life threatening cancers.'
Anderson shocked the world in November 2015 when she announced she was cured after completing a 12-week regimen of a 'miracle' drug - at a cost of almost $100,000. The medicine hit the market in December 2013. Since then, tens of thousands have taken it in one of the fastest roll-outs in the history of modern medicine.
A friend close to the star told the Enquirer, 'She's thrilled to no longer have that sword hanging over her head, but id' expect she's also terrified that the cure may lead to something worse.'
Pam has yet to respond to the publication's claims.
