Is there such a word, linfedema?

Question

Is this a valid word in Spanish? What is its gender? Thanks

Answer 1

Yes, it is masculine.

For those unfamiliar with lymphedema:

linfedema

Answer 2

Linfedema

I cannot find it in RAE but it is in wikipedia and elsewhere on the internet. The English, of course, would be lymphedema, but I am not sure if there are other, more preferable terms to a native Spanish speaker.

Answer 3

I don't think it is a word.
