Histopathology of invasive<unk><unk>  (ILC), next to<unk>  <unk> .<unk>  neoplasia is considered pre-cancerous, and<unk>  is an indicator (marker) for increased risk of developing invasive breast cancer in women. This risk extends more than 20 years. Most of the risk relates to subsequent invasive ductal<unk>  rather than to invasive<unk><unk> . Older studies have shown that the increased risk of developing invasive cancer is equal for both breasts, and more recent studies suggest that while both breasts are at increased risk of developing invasive cancer, the ipsilateral (same side) breast may be at greater risk. On the other hand, analysis of SEER data (Pooled data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results program) revealed the cumulative risk of developing invasive breast cancer after<unk>  diagnosis to be 7.1% at 10 years, with equal predisposition in both breasts. The annual risk of developing invasive breast cancer after a diagnosis of<unk>  ranges from 1-2%, and the invasive cancers may include intraductal<unk>  as well as intralobular<unk> , with increased risk of developing invasive ductal. Research regarding the cumulative risk of developing invasive cancer at 5 year intervals varies, with the risk at 10 years being 13—15%, the risk at 20 years being 26-35%, and the risk at 35 years being between 35% and over 50%. The relative risk of developing invasive<unk>  after<unk>  diagnosis is 8-10 times greater than in the general population.
