Suggest youto hv second opinion , you may get the second opinion in Singapore, as there is many oncologist availlable and there is also John Hopkins in Singapore, if you want the contact, i will advise to you.
As per your message , Doctor finding is Malignant and after the removal of adrenal tumor and lung lesion, it's Benign.
So,the question now is that the tumor in your upper L lung is Malignant or Benign ? if it's Malignant, it's very strange that Doctor not suggest you to start any treatment , i.e. Chemo .
I hv discussion with many oncologist in Malaysia and Singapore ( including the oncologist from John Hopkins USA ) and all of them advise me that operation is not a need for me, when the CT scan and Pet Scan confirm that my lung cancer already cause lesion to my lung wall ( means , it's already spread ) and it confirm as Malignant by the pathologist , after they perform biopsy procedure to remove some tissue of the tumor for test .
CT scan can not give us any confirmation whether the tumor is Malignant or benign.
