Hi there…There is no reason why you cannot go undergo breast augmentation if you have hepatitis C. That said, you will likely need medical clearance prior to proceeding with the operation to ensure that your liver function has not been affected by the disease or that there are not other medical conditions that are of concern. In that light, your abnormal white blood cell count should be evaluated to ensure that there are no underlying medical or hematologic problems.It is absolutely critical that you seek the advice of a plastic surgeon who is certified by the American Board of plastic surgery, and get the advice of your primary care or specialist physician to complete your preoperative medical clearance.I wish you the best!Dr. Gabbay.
