In most cases, breast nodules may be more serious than breast cysts because breast nodules can be of many types, such as fibroids or even malignant tumors, while breast cysts are benign lesions, but larger breast cysts are also more serious, so the decision needs to be based on the patient’s specific condition. After finding a breast nodule, you need to go to the hospital as soon as possible to improve the relevant examinations, such as breast ultrasound, mammography X-ray, breast MRI, etc. If necessary, you need to do a puncture biopsy or excisional biopsy of the nodule to clarify the nature. If the nodule is considered benign and not painful, it is not serious and can be observed regularly, or removed by medication or surgery if necessary. If it is considered to be caused by malignant tumor, radical resection of the tumor is needed, together with other treatments to prevent the condition from worsening and affecting the patient’s life.
