My husband is 77 with Myelofibrosis and we just learned his nodule middle lobe grew 4 mm from January to April and is spiculated. After pneumonia infection is cleared will have a PET scan. I wish they removed it when it was small and harmless. I am so worried for him, we have been married 38 years, he is coughing constantly and he is inpatient with IV antibiotics to clear the pneumonia but this one is so much worse than the last one he had.
