I have a significant scoliosis. what is the best breast radiation treatment to avoid damaging the lungs?

Let me explain: Talk to radio-therapist and tell him about about concern, I am sure he will address them for you.

Does not apply: This question deals with radiation oncology as far as i can tell based on the term 'radiation treatment'. This is best asked to a radiation oncologist. If you are asking for how to assess scoliosis and minimize radiation to the lungs then a radiographic (x-ray) scoliosis series is best.

None: Scoliosis is a curvature of the spine and radiation does not correct that. Radiation treatments are for specific malignant conditions.

X-rays from back: Shielding the breasts can be done with experienced pediatric technologists. The x-rays should be taken with you facing the detector or film so the beam enters your back first and limits exposure to the breasts which are away from the x-ray tube source. Damage to the lungs is of less concern than exposure to the breasts.

3D Planning: External beam RT to the whole breast after lumpectomy can usually limit significant doses delivered to the lung tissue with modern techniques (i.e; 3D planning or IMRT). With scoliosis, it is important to use proper immobilization devices during the simulation/mapping to assure reproducible daily alignment during the treatment. Another option (if early stage) is internal RT or brachytherapy.
