When I first discovered my lump last September, I was sent for an ultrasound and biopsy.
The ultrasound showed that my left thyroid was partly covered by nodules and the other part was bleeding into itself.
The biopsy results came back as benign but what I didn't know was that in Australia they only select the largest nodule for testing. My malignant nodules were some of the smaller ones that weren't picked up until I received the pathology results from my partial thyroideectomy.
I only went to see my surgeon so I could understand the full process as my Endo advised me that I didn't need to have it removed unless it continued to grow. whereas my surgeon recommended it's removal as it had bleed for a second time in the 2 weeks between my Endo appointment and seeing him.
Then based on the opinions of my surgeon, GP, Endo and my personal research I decided to have my right side removed as there were signs it may have spread to my right Thyroid. But, after my surgery it was confirmed that it hadbt spread.
The best advice I could give you is to do some of you're own research and follow your instincts, this forum helped me a lot too!
It's pretty scary when you've gone from having no issues to being told about a possibility of cancer.
