Breast nodules are generally difficult to rub open, and it is usually not recommended that patients deal with them through massage and other methods, as there is a risk that the nodules will increase in size during repeated stimulation, and there is also a risk that the nodules may become malignant and progress to malignant tumors of the breast. If you find a nodule in your breast, you need to go to the hospital for an ultrasound or mammogram to determine whether the nodule is benign or malignant, so that you can guide the next step of treatment. Some breast nodules are benign, such as breast fibroids, which usually have clear borders and are very mobile, while others are malignant when they first appear and may not have clear borders and may be more fixed. So when a patient has a nodule in the breast, without determining whether it is benign or malignant, massage and repeated rubbing may lead to an increase in the size of the nodule and may also lead to malignancy.
