Thanks for Information .Makes me fill a little Better
I am not a doctor, but I did recieve Radiation for my Cancer in the Head and Neck area.
This was back in the winter of 2005, and I still have a very dark tan from where I was burnt by the radiation. I was told to wear a hat, and to make sure my face was protected from the Sun always. My skin would be very fragile to the Suns Rays and this is to protect me from Skin Cancer. It doesn't hurt to get a Doctors opinion on your concerns. I don't believe you should have any concerns about your Lungs or Bladder.
Have some blood work done and maybe a CT Scan of your Chest. Just go to your Doctor. If you have any concerns on your health you should look into it. You are in control of yourself. I wish you all the best, and stay positive.
