papillary thyroid carcinoma Is it unusually large?

Hello and welcome to e health forum. ‎

The size of the keloid, that will be formed is not dependent on the size of the tumor. But it ‎is certainly related to the size of the incisions made during the surgery. ‎

But in case of papillary cancer, multiple incisions made be needed, to make sure that cancer ‎cells are completely removed. ‎

First and foremost, you need to undergo effective treatment for the thyroid cancer. Once it ‎has been done, care should be taken to allow proper healing and reduce the amount of ‎scar tissue. In case keloids are formed at a later stage, then proper steroid injections ‎should be given at the early stages, to help prevent keloid formations. ‎

I hope this helps.‎
