Yes: But only for thyroid cancer.

Probably: The purported reasoning is that the increase in thyroid hormone causes a chronic inflammatory condition in the ovaries, leading to the cancer. So yes, rai should cut down thyroid hormone production, which should mitigate the risk; that being said, ovarian cancer is fairly rare, with incidence of about 10 per 100, 000 females in the us, average. 80% increase would be 18 per 100, 000.

Not really: Rai won't lower your cancer risks. It may actually increase it later in life. However an untreated graves condition poses risks as well but not an 80% risk of cancer.

Considering she said she's been well controlled for 6 years, it doesn't sound like she's untreated.
