Hi again Skeeter,
After what you have already been through, radiation will be a breeze!! Really! The people at the Cancer Centers are all so loving and caring, and you will be amazed at quickly the 6 1/2 weeks goes by. Try to get to know some of the other patients whom you will meet there. We got to where we looked forward to seeing one another each day, and would check on how we were feeling, and giving support to each other.
The simulation before the actual treatments begin is to prepare for your exact positioning on the table. Here, I was actually molded into a "cradle" that fit my body. Then when you go in each day, you lie in the cradle and it holds you in the perfect position. The mapping I had done with tattoos, although they also used pens periodically. The tattoos hurt for just a moment...I got four, on the perimeter of my radiation site. Be sure to remove the ink makings before you get dressed each day (unless they tell you not to!) so they don't stain your clothing.
If you are having problems with mobility and range of motion in your arm, do ask your surgeon for a referral to a physical and/or occupational therapist. I could not have gotten through this whole process without them. They taught me exercises to minimize the chances of getting lymphodema, and helped me to regain most of my range of motion. Also, to get into position for the simulation, you must be able to raise your arm above your head. Without their help, I never would have made it.
Glad to see are going to eat healthy...my motto for getting through just about everything, Eat healthy, exercise daily, and rely on your support people. You will do great...just remember, this is a temporary problem that will be behind you soon.
Sending love and hugs to you.
Take care, Jean in WA
