A growing cavitary lesion is most likely to be inflammatory, infectious, or malignant (probably in that order of likelihood for you). There is a long list of possible causes. Something that big likely warrants further investigation, potentially with a biopsy. The pulmonologist will be able to further narrow what the possibilities may be (heavily dependent on where you live and in-depth past medical history).
[32M] Lung Nodule Time!Age 32Sex MaleHeight 6'0Weight 190lbsRace WhiteDuration of complaint: Just startedLocation: Lower Right LungAny existing relevant medical issues: DepressionCurrent medications: WellbutrinHello, everyone. I know lung nodules are typically nothing, but I can't seem to find a whole lot. And I know wait on my pulmonologist appointment to go over the findings. So naturally I'm freaking out anyway.So last year I had gallbladder surgery so I had a CT scan done. I had another one today for something related to urology and a swollen lymph node (everything fine there) and that's when it was discovered.From my understanding, they compared it to the CT scan from January 2021 to the CT scan today, and it was 1cm then and now it's 2.7cm. I was diagnosed preliminary with a lung nodule that has grown into a cavitary lesion by the primary doctor and he's referring me to a pulmonologist. I currently don't have any symptoms.I know it could be dreaded cancer but is there anything else it could be at that size? Most of what I've found online is people talking about 10mm or less.Thanks for any input. I am just looking for possible alternatives so I can focus on that and can sleep until my appointment.I am 32M. 190 lbs and 6 feet tall. I currently take Wellbutrin for depression. I don't drink, I don't smoke, I don't do any recreational drugs. I had asthma from around age 5 until 21/22 when it went into remission. I had pneumonia once when I was 5.
