There seem to be 4 types of thyroid cancer. Anaplastic type being the most aggressive. We all pray that it is not the card you've been dealt. I've observed for two years for you to be a dot connector/researcher extraordinaire and I have always enjoyed/amazed what you come up with. No doubt you'll do the same on yourself. I will point you though to something pointed out to me once," poking holes in it" biopsies can cause cancer cells to metastasize. They call it "tumor seeding through the blood stream". Many medical journals on such to look up about it. And boy do they love to do that here in the USA as opposed to excisional biopsies they do in other countries. Take out the lesion and then biopsy it with much less chance of 5 to 10 year spread to other parts. And usually upwards from the original site.
It also gives credence (IMO) to the theory that cancer is a parasite.
Healing vibes being sent your way. Love.
