Thanks for contacting HCM. You are concerned that taking levothyroxine will increase your risk for breast cancer. There is no association with levothyroxine and breast cancer. I can reassure you that you have nothing to worry about.

Thank you so much! Makes me feel better! But you forgot to answer on my iodine supplement, do i need to take one?
Brief Answer:
Iodinesupplementation not needed
Detailed Answer:
Thanks for contacting HCM and me with your question. I am sorry I did not address your iodine supplementation question. The short answer is that iodine supplementation is not required. In the United States all salt has iodine added to help the general population keep adequate amounts of iodine in their diet.
Before Iodine in salt children did not get sufficient iodine and developed hypothyroidism but since the addition there is no further risk from iodine deficient cause of hypothyroidism.
You can take a supplement if you like but it is not needed as an XXXXXXX adult gets plenty through a regular diet.

So if i decide to take extra iodine, will it hurt me or is the extra your body doesn't use beexcreted thru one's urine?
Brief Answer:
Extra iodine is excreted
Detailed Answer:
Thanks for contacting me again.
Yes the extra iodine is excreted and there are no down sides or side effects from taking too much iodine. In my practice I do not recommend my patients with hypothyroidism take iodine supplements.
