Brief Answer: nothing to worry about Detailed Answer: Hello Thanks for your query. Atypical adenomatous hyperplasia is a pre-cancerous state but not a XXXXXXX malignancy. Many a times pathologist cannot differentiate between non-malignancy and atypical adenomatous hyperplasia. As lung resection had already been done that means optimum treatment for it has been done. What you need is follow up computed tomographic scan yearly to look for any recurring nodule or ground glass opacity on lung field. Atypical adenomatoid hyperplasis is of good prognosis and you have received the definite resection in the form of lung resection and chance of recurrence is low. So don't worry for that. Just have a follow up scan yearly. If you have further queries you can write back to me. If you are happy with me you can write a review for me. God bless you. Thank you Regards Dr Arnab Maji MBBS, MD Consultant Pulmonologist

Brief Answer: Multiple factors including genetic factors Detailed Answer: Hello, Thanks for your query. As I earlier said it is a precancerous lesion and a fore-runner of adenocarcinoma of lung, so the same causative mechanism of adenocarcinoma may prevail like genetic mutation, familial predisposition, cigarette smoking, environmental exposure, dietary habit and its next to impossible to say what exact mechanism is working here but the chance of cumulative results of many factors is more common in the causation. You are very lucky that it has been diagnosed in the precancerous stages and probably in the curable stage. Don't worry at all. If you are happy with my response kindly write a review for me.
