[|AI|]  Thanks for your question on Chat Doctor. Your description of mass favors malignancy. As lung cancer especially squamous call carcinoma grows in Hilary area and has peculiarity to invade surrounding nearby vessel. Benign cyst or benign soft tissue mass does not invade vessels. To invade vessel and encasing it, is the characteristic feature of malignant mass. So get done biopsy as soon as possible for confirmation of diagnosis. Also get done PET scan to see for distant metastatic lesions.
