Just wanted to thank everyone for the warm welcome. Andrea, I am 21 years old. The reason I questioned preventative testing is that there are things that have (medically) happened to me recently that are almost identical to what happened to my mom when she was my age (I wont go into detail publically yet though). I smoked for 5 years. From ages 16-20. I quit last year when I had a good opportunity (surgery). Still, I'm sure that alone puts me at some sort of risk. Snowflake, after reading your post I felt sick to my stomach. I cannot for the life of me figure out why doctors do not check things out that are blatantly suspicious. If there are an abnormally high count of white blood cells, why not find out whats causing that to happen??? I know my mom could have been diagnosed at least months before she was, she had just about every symptom lung cancer actually does cause. Before I was thrown into this living nightmare I had no idea what I wanted to do with my life. I now have some direction... I'd like to be involved with finding the cure.
