Hair is one of the most common concerns people raise before radiotherapy, and for most of them the answer comes as a relief. Radiotherapy only acts where the beam is aimed. Scalp hair therefore only falls out if the scalp lies inside the radiation field: with radiotherapy to the breast it is spared, while hair inside the field itself can be lost, in the armpit for example. The German Cancer Information Service at the DKFZ puts it this way: radiotherapy only damages the hair in the area the beams reach, whereas hair loss across the entire head usually comes from chemotherapy. If the head lies inside the radiation field, the loss usually begins 2 to 3 weeks after the first session.<\/p>\n
