1. When a tumor decides to moonlight as a pancreas and uninvitedly drops your blood sugar. (IGF-2 says, "I got this!")

2. The "how squished is your chest?" ratio, determined by CT. If it’s too high, your sternum might be getting too friendly with your spine!

3. The ultimate VIP pass to the anterior mediastinum—if you ever wanted to poke around someone's left lung the surgical way.

4. The most common benign lung tumor—because even tumors can be harmless and just hanging out for fun

2. The "Oops, I hit the sympathetic chain" trio: ptosis, miosis, and anhidrosis. Basically, your eye decides it’s taking a nap... permanently.

6. The most common lung cancer subtype because, apparently, lung cells didn’t get the memo that "mono-differentiated" isn't a cool trend.

7. The max air your lungs can hold—basically, if you were a balloon, this is when you’re one deep breath away from popping.
