Your client probably has low stomach pH, weakened immune system, and poor diet and/or absorption of nutrients.
What tests did the docs do exactly? What's her diet like? How old is she? Figure out why her GB was removed? No gallbladder means poor fat digestion, she can't simply eat whatever she wants anymore.
What tests did they do to suspect lymphoma? It could be the diet/absoption/h pylori issue involved.
Plus, Iodine is never taken alone, there's a host of other co-nutrients required like Magnesium, Zinc, etc... there are many documents sprinkled around the forums.

Iron should be taken in food form, iron rich foods. But her digestive/absorption problem is more than likely the primary contributor to her poor health.
I hope her the best, but she needs some tough intervention quick. How do you say: "You need a lifestyle change" nicely, if it truly is a poor lifestyle that she's practicing? I'm sure others will chime in soon.
