Invasive ductal carcinoma of the breast carries some familial risk, but is not always inherited. Regular breast cancer screening is recommended for those at high risk for early diagnosis and treatment. Although people with a family history of invasive ductal carcinoma of the breast have a higher risk of developing the disease than the general population, it does not necessarily mean that the next generation will have breast cancer. Current research shows that breast cancer is closely related to specific genetic susceptibility alleles, but its cumulative risk is lower than that of classical tumors such as uterine cancer and colon cancer. In addition to this, there is a link between the development of breast cancer and ionizing radiation, obesity and diet. It is recommended that high-risk groups undergo regular screening such as clinical breast palpation and mammography.
