New and confused

Hi

Welcome to the group. I’m sorry I don’t understand the grading of lumps but I’m sure someone on here will be able to advise. This should bump it up to the top again and hopefully someone will be able to help you. 

Ultrasound is just the first step in determining whether you have cancer. U5 indicates there are signs that support that possibility.
If you didn't already have a fine needle aspiration, that will probably be the next step. 

Analysis of that small sample will give the team more information to support a possible diagnosis. 

It's not yet guaranteed, but the balance of probability probably lies towards you needing to have the lump removed - unless it's particularly small. There's a lot more 'watch and wait' going on these days. The docs will consider what's best for you and take your past cancer experience into consideration. 

Try not to get too hung up on the medical terminology which really makes little sense to anybody who isn't an ultrasonographer.

The 'good news' (if I can call it that) is that thyroid cancer is almost always very treatable and probably quite a different experience to your breast cancer journey.
