scary to say the least. sorry you are going through this. i can tell you i had a much larger nodule that turned out benign. hoping the sane benign outcome for you too., many reasons you may not pass a physical for surgery. all patients facing any type of surgery serious or routine go through tests to find out if healthy enough for surgery. if not healthy enough, such as the simplest issue low in vitamins, high or low blood pressure, serious or not so serious issues, for example can be treated until you pass a health test and get go ahead. wish your doctor hadn't told you its probably malignant, only a biopsy can make that determination. wishing you peace, good doctors and a great outcome.
