I have multifocal lung cancer (multiple cancerous nodules in my lungs-a chronic situation) which was diagnosed in Dec 2021 - I had my first case of Covid 2/1/2022 one month after first lung surgery - despite my isolation to avoid Covid. Thankfully I was vaccinated, and I had a mild case, just a congested cough which went away with antiviral treatment. So no, Covid did not cause my cancer. Research lung nodules, they are common and can be many things.
I caught Covid a second time in August 2022 with barely any symptoms.
As information comes in, it would appear that catching Covid multiple times is not good as one can have various health issues down the road. And people with long Covid are having a bad time.
