Hi @delormv, having already had DCIS in your left breast, I can imagine that you're concerned about no treatment for atypical lobular hyperplasia found in your right breast. I'm tagging fellow members @cindylb @casa @tommie57 @sorrel to share their ALH experiences with you. Additionally @kk57 and @pharmmom4 also had ALH at the same time as having breast cancer in the other breast.

You might also wish to see this discussion that @elsie37 started a little while ago.
High risk, NOT from BRCA but from typia, such as ALH, ADH, LCIS https://connect.mayoclinic.org/discussion/high-risk-not-from-brca-but-from-typia-such-as-alh-adh-lcis/

Mayo Clinic suggest surgery as a treatment option.
"Atypical hyperplasia is generally treated with surgery to remove the abnormal cells and to make sure no in situ or invasive cancer also is present in the area. Doctors often recommend more-intensive screening for breast cancer and medications to reduce your breast cancer risk." Read more here

Delor, have you considered a second opinion?
