I have chondrosarcoma. I just had my fifth surgery on the 6th. My first surgery in 2012 they removed a 4-1/2 lb tumor from my lung. Two years ago they removed my right lung. I now have seven tumors in my left lung. I won’t undergo surgery on that until it is absolutely necessary as I am kinda addicted to breathing😂 Chondrosarcoma is extremely rare. My do tor is on two Tumor Boards and they are at a loss on treatment. Basically, there is no treatment. Knowing that in a few years I will either have a diminished life or lose it, I keep a positive attitude. I enjoy every day that I have. I refuse to stress over what cannot be changed. Life is a gift, and God has a timeline for all of us. Enjoy your life. Be sure your doctor networks with other doctors. God bless
