OP- I realize that you have had to deal with a lot of heartache . I do want you to put yourself in your friends shoes and understand how difficult it must have been for her to hear that she has cancer. No matter what her treatment plan was, she probably worries every day that it might come back. As you know, each time she went in for scans, the anxiety and worry is tough.
We can all agree that she is fortunate enough to not have had to had chemo or radiation. I'm sure she is not trying to compete with others who have . She is just celebrating the fact that she survived cancer.
My son was diagnosed with a rare cancer in his hand and had it surgically removed and did not have chemo. He did have radiation for 5 weeks. It has been 9 years and we just found out that his cancer has metastasized to his lung. I remember my sister-in-law had a friend who had a child with a brain tumor that was discovered at the same time as my sons tumor in his hand. She actually told me that my sons cancer was nothing like what her friends child was going through. Yes, that child had to have chemo, missed a ton of school, and has permanent disabilities caused by his treatment. I would never argue that his course was much tougher, but the anxiety that my child had to go through, and years of testing was so scarey. We almost made it to the magical 10 year mark.
We never know what the future holds. What might seem small and somewhat benign could be much more than what it seems. Cancer can surprise us all.
Try to be happy for your friend.
