No one ever developed cancer due to a deficiency in chemo. The same cannot be said about iodine, Vitamin D3 and other natural essentials that many of us are deficient in due to our SADS diets, depleted soils and over-processed foods on our grocers shelves.
I might also note that while I am not familiar with oxidative damage due to iodine I have seen studies that indicate oxidative damage due to iodine deficiency. For example:

All halogens are Oxidizing. (F2, Cl2, Br2, I2). F2 is most oxidizing and I2 is least oxidizing.
Oxidant is a substance which will steal electrons ( gain electrons) and itself get reduced.
Hence F2, Cl2, Br2, and I2 get reduced to fluoride, chloride, bromide and Iodide respectively.
fluoride, chloride, bromide and Iodide are reducing agents ( aka antioxidants).
So consuming Elemental Iodine is OXIDATIVE THERAPY and consuming IODIDE salts (eg KI) is antoxidative therapy.
Oxidative therapy has the potential of killing harmful stuff, but it also has the potential of causing damage to our healthy cells as well. Chemotherapy, Radiation and even H2O2 and ozone are all oxidative therapies.
The emphasis on Vitamin C when supplementing with I2, is because Vitamin C is an Antioxidant, and may undo the damage done by Iodine. But why take elemental I2 in first place. Why not stick with reductive therapies? makes me wonder.
Yeah, you are right. Oxygen which is a life giving gas, is needed by all living things to survive. But Oxygen causes Oxidation and free radicals, and body must continously produce Anti-oxidants to undo the damage done by oxidation.
Oxidation and Reduction are both happening in our bodies, but if we overload the body with plenty of oxidants, chances of damage to our cells increases.
Aging is caused when the oxidative stress of our body increases and body cannot get enough anti-oxidants to fight the oxidative stress. fact is, we are all slowly oxidizing/ rusting away. the result is wrinkles, gray hair, weak eyesight, just to name a few symtoms.

"The oxidative challenge in biology
Further information: Oxidative stressThe reactive oxygen species produced in cells include hydrogen peroxide (H2O2), hypochlorous acid (HOCl), and free radicals such as the hydroxyl radical (·OH) and the superoxide anion (O2−).[12] The hydroxyl radical is particularly unstable and will react rapidly and non-specifically with most biological molecules. This species is produced from hydrogen peroxide in metal-catalyzed redox reactions such as the Fenton reaction.[13] These oxidants can damage cells by starting chemical chain reactions such as lipid peroxidation, or by oxidizing DNA or proteins.[9] Damage to DNA can cause mutations and possibly cancer, if not reversed by DNA repair mechanisms,[14][15] while damage to proteins causes enzyme inhibition, denaturation and protein degradation.["
