ET, cancer or not? I realize doctors disagree. But be aware that if you are applying for more life insurance, one question is "have you been diagnosed or treated for cancer in the last year?"

If your insurance company defines ET as a cancer and you tick "no," you may jeopardize your policy.

It's hard to find answers on this, but one patient handout notes that insurance companies vary. https://www.medlink.com/handouts/essential-thrombocythemia#

Please discuss this with your insurance agent if you are in the market for life insurance.

Gotta love ET. It probably won't kill you, but it will complicate a lot of stuff!
