Hi David. I'm sorry you've lost your wife and that you're facing this without her support. But just as you supported her with great strength, she would want you to keep the same strength in caring for yourself. Please insist on a biopsy immediately. My mom was very patient with all of the tests & referrals to many doctors. She eventually saw an oral surgeon who performed the biopsy that diagnosed her with Stage IV OC. With prayers and very supportive, talented drs. her OC has not returned. Stay strong and keep your determination and faith going!
