Hello Gina:
Thanks for contatcing me. I am a nurse in the USA and have had Hashimoto's thyroid disease since 1987 and 3 nodules also.
We only get 1 thyroid and we need the gland and it does not grow back or regnerate itself.
Nodules can be from a few factors, lymph tissue or redundant fat cells and some are thyroid tissue that replicates itself but it does not mean cancer.
So atypical means not conforming as regular tissue. Colloid is a tissue that is gelatainous or jelly like. Some nodules are cystic like and have an old fluid or jelly like matter in them. They are mostly NOT CANCEROUS and are clumping together and made a cyst there or nodule. Cysts will swell and sometimes go back down as the cellular fluid can dry up over time and or be drained if they can reach it.
Cancer makes a hard lump normally and a dimpled appearance on the skin and usually is not colloid.
Nuclear is relating to the cells and microfollicular means small areas with grooves which goes along with cysts like behavior.
Most common causes is an old infection and it made a cyst. Some people also have a family history of it. Some women even get them on their ovaries too. They call it Polycystic Ovarian disease. NOT at all a cancer! Also autoimmune diseases can make you more prone to cysts/nodules.
Removal of the lobe of your thyroid should be a last resort!!! Of course the only way to really know what is there is to remove it and send it to pathology.
They can watch it by doing an ultrasound in 1 years time, and if it changes size then consider surgery if needed. A naturopath can also help find natural diet plans and balance your immune system out by way of natural herbs and plant meds.
I would see if it is making you Hypothyroid, as some of these cysts can make it hard for a lobe to do it's job. You can take replacement hormone for that.
FNA (fine needle aspiration) can give you a good idea of the makeup of the nodule. So I am pretty sure it is a cyst and not a big problem.
As long as you are not have swallowing problems or any sticking feeling in your throat or problems in breathing you can watch it.
Eat a good diet and reduce risk to infections helps. If you had a lot of viruses in life or Epstein Barr disease also known as MONO, amke sure they test for Antibodies test called TGab and ANA Direct and TPOA. These blood tests are simple and can show an autoimmune problems.
Avoid Gluten and junk foods, make sure all minerals calcium, potassium, sodium, and zinc, and magnesium are okay. Make sure your Red Blood count is okay. Cancer can make Red count and sodium go off.
Any questions just ask,
Shelly
