Adenocarcinoma in Situ or Ground Glass Opacity Nodules


March 26, 2018 at 8:36 pm #1294136

I’ve got two stable ground glass small lesions (one 5 mm and another faint one 5x9mm) in my right lung and have been reading about other people’s experiences with them on the web.

On a different forum it is often stated that these lesions rarely grow large, but I thought it was the case that they can grow large but are not called AIS when they grow to larger than 3 cm so it is only a question of definition rather than related to the natural life history of these lesions.

Watching Small Lung Lesions Do Nothing: "Ground Glass Opacities" Don't Progress Over Years If They're Watched, Not Resected


In one of my earliest posts about bronchioloalveolar carcinoma (BAC) (in the dark ages, pre-Twitter), I wrote on the subject of managing small BAC-type lesions, which tend to appear as small hazy areas called "ground glass opacities" (GGOs) and suggested that some of these cancers may be so indolent that they don't need to be treated, even if they have the word "carcinoma" in the diagnosis.
