Same here, I was diagnosed Multifocal Adenocarcinoma Lung Cancer a little year ago. I never smoke, none of my family and friends smokes. I went through 2 VAT surgeries, the 2nd one was just 3 weeks ago.
I decided not to tell siblings who live out of state, except one brother who lives near me. I told that brother not to tell the other siblings. I also don't tell friend, and my colleagues.
I am 76 years old, I still have a job I love, I work remotely, I went to office once a week when it is necessary. I don't want to give up my job, I don't want anyone to pity me.
I know this cancer journey will be long and difficult. Telling them is of no use.
