My daughter has just finished her sixth week of external radiation therapy for cervial cancer (Stage IIB). There was no notable shrinkage of the tumour until the end of the fourth week. After five weeks, however, it was reduced to one-third of the regular size.She continues to have bleeding after radiation, and she is wondering if that means that the tumour is still present. (She won't have another exam until next week.) Or does bleeding occur as a side effect of the radiation treatment?
