@sahiltaneja - Good morning and welcome to Mayo Clinic Connect. It must be a tough time for you. When my mom was ill my heart broke.

Hypermetabolic lymph nodes were caused by your mom's immune system, most likely and probably from COVID. This means that they have swollen which makes sense. It could also be a combination of both cancer and COVID reaction. People who have had Covid vaccinations also get this reaction quite often. Non Avid lung nodules have to do with a reaction to an antigen which I simply do not understand.

As far as treatments for your mom it will depend on what the biopsy shows and it depends on what your mom wants to do. Adenocarcinomas can be treated quite easily now with quite a few options but it really does depend on her medical history, her other illnesses, if there are any, and other factors that would be considered for any operation.

How is your mom and and how is she reacting to her news of having lung cancer? And how are you?
