Can mammograms screening done earlier than 40 in women

Can mammograms screening done earlier than 40 in women?

Women who have been treated for Hodgkin lymphoma should begin screening 10 years after chest wall/mediastinal radiation. Patients who received radiation therapy during puberty are at greatest risk for breast cancer, whereas those who received radiation therapy after age 30 have a minimally increased risk over the general population. For patients with a history of a first-degree relative with breast cancer, screening should begin 10 years before the age at which the relative was diagnosed. If the relative was diagnosed after age 50, there would be no impact on the screening recommendation. If the relative was diagnosed before age 50, the woman should begin screening before the age of 40. Women with genetic mutations also begin screening at an earlier age. These include BRCA1 and BRCA2 mutation carriers as well as women with PTEN mutations. Also included are women and their first-degree relatives with the following syndromes: Li-Fraumeni, Cowden, and Bannayan-Riley-Ruvalcaba.
