1. With the advent of higher voltage irradiation there is an increased danger of damage to the deeper tissues in the irritated area.
2. Bone, as well as the soft parts, is subject to injury by the roentgen ray.
3. If radiation osteonecrosis involves the femoral neck, spontaneous fracture may possibly occur.
4. When there is pain about the hip joint following irradiation for gynecological cancer, skeletal metastases should not be assumed without definite roentgenographic evidence.
5. In no way is the deep roentgen-ray therapy condemned, nor is its efficacy in pelvic malignancies questioned. We should continue its use and at the same time be alert to its unavoidable complications.
