A member asked:

How rare is a positive cdh1 test? my dad & two of his siblings died of stomach cancer before 40, youngest was 21. considering genetic testing

A doctor has provided 1 answer

Just get it: You have asked more than once and this shows determination. That is commendable. It may be pricey but you want to know. Just that desire, well educated, is reason enough. A clinical geneticist may be a helpful guide.
