Breast lobular tumors have a small chance of being malignant. Lobular tumors of the breast are a rare disease that occurs in women’s breasts and can be classified as benign, junctional, or malignant based on pathological findings. Clinically, benign or junctional tumors are common, and malignant tumors are rare. It can develop in women at all ages, with 40 years of age considered to be the peak of incidence, and is more frequent before and after breastfeeding and menopause. It has been found to be associated with endocrine hormones and is mostly benign in the early stages. Lobular tumors of the breast have also been found to occur on the basis of breast fibroids. The treatment of lobular tumors is complete surgical excision. Incomplete excision can lead to recurrence, and complete excision again can still achieve a better result, but if it is malignant, it can lead to serious consequences through lymphatic and hematogenous metastasis. If you have lobular tumor of breast, it is recommended to go to the hospital in time and follow the doctor’s advice.
