IDC + Hashimoto's thyroiditis

Hashimotos is very common, especially in women, and when it burns out into thyroid underfunction, you get thyroid supplements to maintain normal function ( TSH 1-2 in most). Endocrinologists who see a new Hashi patient do not immediately refer for breast cancer screening because there is no known association. Both are just common in women.

There is, however, an association with autoimmune low b12 and other autoimmune problems, including rheumatoid arthritis, and celiac disease, so at least check the b12, is easy to supplement, and if you have arthritic or GI symptoms that could be managed.

I too had Grave's back in the early 2000s. I have Hashimoto now. Both run on my mother's side of the family. I'm the only BC diagnosed person on that side of the family and there are a lot of relatives (she has 8 sisters and two brothers). They all have kids and there kids have kids. Seems BC was a fluke for me.

I have had Hashimotos for a little over 30 years. Your thyroid levels will change a lot while they are trying to regulate your meds.

Find a good endo. one that listens to you and not your lab work. There is a normal range for labs but most patients feel better with their TSH in the lower range of those levels.

The most Synthroid I have been on was 200 mcg right now I am on 150mcg. My Hashis came first and the breast cancer for me just happened.

Hi Carolina1987. I have hypothyroidism, fibromyalgia, nerve damage and arthritis. I was just diagnosed with multifocal invasive ductal carcinoma. My doctors say there is no corolation but I have read that women who have breast cancer have a 50% higher probability of developing thyroid cancer. Good luck! I am still debating lumpectomy or mastectomy. Very stressful. I am er/pr + her2 - and will be put on hormone meds for 5 yrs.
