Hi, can I answer your health question? Please type your question here...Thank you. I am a female, age 68.5, active, normal BMI with a chronic large granular lymphocytic leukemia...in watch and wait (15 yrs). I hav had two EKG tests...3 yrs apart stating “possible left atrium enlargement”....my internist feels continued exercise and maintaining good blood pressure (I hav had mild hypertension over 20 yrs).... is the best and “any further testing at this time isn’t needed”...... should I get an opinion from a cardiologist for peace of mind? Either I have an enlargement or I don’t. “Possible” seems vague to me. Barbara
