I was 35 years old when they found out about my thymus cancer. It was found by accident. I had hurt my arm and was in a lot of pain. They could not figure out what was wrong with my arm and decided to take me to surgery and see if it was a misplaced nerve. [it was and they fixed it] They decided for some reason to give me a chest xray before surgery and that is how it was found. Looking back I can see that I did have symptoms. My heart would beat wildly at times [thought it was too much coffee] My heart was being squished because of the tumor. When I would cough it was bad. I could not get my breath. The tumor did some damage to my lungs. I still have a problem when I get a cold and need to cough. I also got a little dizzy at times. Remember I was 35 and at that age it is rare to have anything like thymus cancer. So most people need not worry.It is RARE.
However it did make me more predisposed to having thyroid cancer. Just need to keep a check on things. I go for my biopsy today and will let everyone know what happens. It will take a week, but regardless. They want to take out my whole thyroid.
