I have been taken medicine for Thyroid for the past 4 years, I have just taken a Term insurance 2 months ago. Now I realize that I missed out to give the information on Thyroid problem. And after starting the medication, for the past 4 years, Thyroid has been normal.

Is there a way to include it now.
If not, if I die due to Cancer or Heart attack, will the insurance company deny the claim because of this missing information.
