Husband has a lump in throat ,non-palpable, and lab results today came back w/low hemoglobin . In the last year he has lost about 10 lbs. he s very thin, eats healthy, and is . He s never lost weight in the about 20 yrs. we ve been together. He s 46 yrs. old. Exercises about 1 hr/day. Former triathlete. Doesn t sit right w/my gut. Many neighbors around 50 yrs. old have had cancer in this area. Live in an active, median income $100,000+ community. Am I overly concerned?
