Hi Chrissy,
My diagnosis of Breast Cancer in Dec 2009 resulted in identifying I had Thyroid cancer (Jan 2010) as well.
Thyroid cancer is usually a slow growing cancer so it is most likely that I had thyroid cancer first.
I am a little unusual as both cancers are primary.
My research has indicated that when a woman has thyroid cancer early in life & it is removed it is possible that 10 to 15 years later Breast cancer can occur due to the taking of Thyozine. It is believed that this drug replacates the neccesary hormones us women need.
There is also another line of research that scientists are following that the hormones these 2 cancers affect are very similar, hence the possible connection.
My oncologist does not beleive that there is an increased risk of me developing secondary breast cancer, so I am invetsigating this avenue of my own. I recently had my 3rd round of radioactive iodine treatment (Thyroid) & spoke to a dr who believes there is a link.
I guess it is an individuals interpetation of things but I certainly would not dwell on the possibility to the point of being distressed, but certainly keep channels open for ongoing information.
Best of luck
Kerry
