I read the following on the Medscape site:

Overall, treatment options for lobular carcinoma in situ (LCIS) include observation and close follow-up care with or without tamoxifen and bilateral mastectomy with or without reconstruction. There is no evidence of therapeutic benefit from local excision, axillary dissection, radiotherapy, or chemotherapy. LCIS in the breast of a woman with ductal or lobular cancer does not require further immediate surgery on the opposite breast. Mirror biopsy of the contralateral breast, once advocated for treatment of LCIS, is now mainly of historic interest.

The National Surgical Adjuvant Breast and Bowel Project (NSABP) P-1 trial prospectively studied the efficacy of tamoxifen in the prevention of breast cancer and included patients with LCIS. [21] The researchers found a 55% risk reduction in women treated with tamoxifen.
