Breast cancer smaller than 1cm is mainly treated by modified radical surgery, breast-conserving surgery, endocrine and targeted drug programs.
1. Modified radical surgery, the volume of breast cancer less than 1cm is small, so it is enough to remove the tissues of the lesion area through modified radical surgery, and then according to the results of pathological tissue examination, it will be determined whether it is necessary to carry out radiotherapy, chemotherapy and other treatments after the operation.
2. Breast-conserving surgery, patients without lymphatic metastasis can also consider breast-conserving surgery, which can not only remove the tumor, but also preserve the breast, only that the whole breast radiotherapy should be carried out in combination with the situation after the surgery.
3. Endocrine therapy, mainly for patients with poor health, old age and other diseases, but need to be estrogen or progesterone receptor positive, using tamoxifen, goserelin acetate extended-release implants and other treatments.
4. Targeted therapy, if the patient is positive for Her-2 expression, he/she can receive targeted drug therapy such as Trastuzumab.
