Hi @Judithm how frustrating for you that you are getting conflicting advice! In regards to the radiation doses and position there are a number of factors that could influence it. The traditional dose is 50Gy in 25 treatments to the whole breast with a further 10Gy in 5 treatments to the lumpsite (not always given) the newer protocol is 42.66Gy in 16 treatments with another 4 treatments to the lumpsite. The 2nd dose regime as mentioned above gives a bigger dose each day. The size of the patient is a limiting factor as the higher dose per day will give worse side effects for larger patients. Also if you are getting your axilla or supraclavicular nodes treated they tend to stick to the longer 25 treatments. I think you said you were right sided which would mean they will be going no where near your heart. The prone position where you lie on your belly with your affected breast falling away is great for large pendulous breasts (no nodes being treated) where lying on your back would cause major skin folds and hence worse skin reaction. But whichever position and for however many treatments the radiation therapists will develop the optimal plan for you.
Best wishes to you xx
