Hello all... Really need to figure out if we should be really worried right now. 75yr old female 4'11" 128lbs White. Been having productive cough (sometimes green) for at least 5 or 6 weeks. Breast cancer in left breast triple, negative Partial mastectomy 5 1/2 years after cancer treatment started, so far no re-occurrence. Medications: Methotrexate, duelera 200mg/5mg inhaler, prednisone (took for 5 or 6 days), Simbastatin 10mg, lisinoproil 20mg, Buspirone HCL 7.5mg 3x day, Flonase, vitamin D, ALSO: Cefdinir 300mg Chest xray showed "left lung increased right vascular OPACITIES with a small right pleural effusion." So her doctor, who we don't have much confidence in, says that she has pneumonia. But he also says that she could have cancer again. Chances are 50/50 he said. He did not admit her to the hospital. How concerned about cancer should we be? And how concerned about pneumonia? I know that the Methotrexate causes immuno-suppression, so that's the likely cause of pneumonia. Thank you so much in advance for your advice.
