    Does anyone know about how many doses (sessions) of radiation are used for different sizes of tumor?

    I'm trying to figure out an estimated, approximate size of my dad's tumor based on the fact that he's scheduled for 13 radiation treatments.

      I have lung cancer also. I don't know if the radiation is different. I had 10 sessions and they were mostly for my back. The first session was approx. 10 minutes and the remaining 9 sessions were approx. 5 minutes each. Since I was laying up on a metal table, some of the stomach lymph nodes were zapped also. My back was very painful, so I had to take morphine (15mg) before I went to each session. The back felt much better a few weeks after radiation. A few weeks later, I had a problem with the taste of food. That recently went away. During the radiation, my skin didn't get burned. I don't know how the radiation went overall. I'm supposed to have another CAT scan in August, so I guess I'll learn the resullts. Good luck with your radiation and please let me know how it went.

      You are mixing apples and oranges. The number of radiation treatments is not proportional to tumor size. The number of treatment is based on a number of factors such as patient tolerance, other treatment planned (e.g. chemo, surgery, etc.) the field and dosage of radiation (not the number of treatments but the radiation intensity of each treatment, etc. If you want to know the size of your Dad's tumor, have his ask his oncologist. A CT scan or MRI is the usual tool for measuring tumor size.

      Might I suggest that you go with your father to his next appointment with his oncologist. My husband would go with me, and we both listened and asked questions. I think you'll find out what you need to know... Or call his office and explain you have questions... I'm sure you can find out more talking to the doctor. Good luck and God Bless your father with healing!
