Customer Question

My 38 yr old son just had a Petscan. The test showed he has 2 golf ball size masses on his lungs, one on his spine and one on his clavicle., he said his only symptom is moderate pain in his clavicle. Am I being naive in hoping it's something other than cancer?

Hello,I am Dr. Aren and I will help with your query.All pulmonary masses will not be malignant,the first step would be to evaluate such masses further.The benign masses would include hamartomas,active granulomatous infections such as tuberculosis,coccidiodomycosis,histoplasmosis,aspergillosis,cryptocoocus.Other causes will inlclude nonspecific inflammation,lung cysts,bronchiogenic cysts,hamengiomas,focal haemmorhages,healed pulmonary infarcts and A-V malformations.Many of the masses will be malignant and may be adenocarcinoma,small cell lung cancer,squamous cell cancer and metastasis from other sites.The size of the nodule/mass also helps determine probable malignancy.In masses over 3 cm in size the probability of malignancy would be about 92-96%,,the probability goes on decreasing as the size of the nodule reduces with nodules of 20mm or less being malignant only 64-82% of the times.Further evaluation by Flexible Bronchoscopy and TransThoracic Needle Aspiration followed by histopathology would help get further information.Early detection and treatment of the malignancy would help check the disease and give a better prognosis.
