Adam’s gifted rib.

It must have been his weakest. This massive meta-analysis of stereotactic body radiation (SBRT) of lung cancers including almost 6K cases of chest wall injuries demonstrated that tumor proximity (within about 2 cm), maximum dose, and the volume receiving at least 30 Gy were all predictors of chest pain or rib fraction. Overall rates of pain and fracture were 11% and 6%, respectively, at median times of 9 and 21 months. But there was one more interesting finding: Women were significantly more likely to suffer a rib fraction. | Ma, Int J Radiat Oncol Biol Phys 2018
