Clinically, the diseases that are more likely to develop nodules are mainly thyroid diseases and breast diseases. 1. For breast cancer, it mainly occurs in young and middle-aged women who develop cystic hyperplasia of the breast, or lobular hyperplasia of the breast. The causes of lobular hyperplasia or cystic hyperplasia are closely related to the imbalance between estrogen and progesterone and lactogen, and the main reason for not eating foods that may contain hormones. 2. There are no foods that can’t be eaten, instead, we need to eat more iodine-containing foods, such as kelp and nori, to promote the synthesis of thyroxine and avoid the formation of thyroid nodules.
