The lobes,lobules,and bulbs are linked by thin tubes called ducts. Anatomy of the breast,showing ...

Breast Cancer Treatment and Pregnancy (PDQ®): Treatment - Health Professional Information [NCI] - Other Considerations for Pregnancy and Breast Cancer
LactationSuppression of lactation does not improve prognosis. If surgery is planned, however, lactation should be suppressed to decrease the size and vascularity of the breasts. If chemotherapy is to be given, lactation should also be suppressed because many antineoplastics (i.e., cyclophosphamide and methotrexate), when given systemically, may occur in high levels in breast milk and would affect the nursing baby. In general, women receiving chemotherapy should not breastfeed.Fetal Consequences of Maternal Breast CancerNo damaging effects on the fetus from maternal breast cancer have been demonstrated, and there are no reported cases of maternal-fetal transfer of breast cancer cells. Consequences of Pregnancy in Patients with a History of Breast CancerBased on limited retrospective data, pregnancy does not appear to compromise the survival of women with a previous history of breast cancer, and no deleterious effects have been demonstrated in the fetus.[1,2,3,4,5,6,7,8,9] Some

Breast Cancer Screening (PDQ®): Screening - Patient Information [NCI] - Risks of Breast Cancer Screening
Screening tests have risks.Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.The risks of breast cancer screening tests include the following: Finding breast cancer may not improve health or help a woman live longer. Screening may not help you if you have fast-growing breast cancer or if it has already spread to other places in your body. Also, some breast cancers found on a screening mammogram may never cause symptoms or become life-threatening. When such cancers are found, treatment would not help you live longer and may instead cause serious side effects. At this time, it is not possible to be sure which breast cancers found by screening will cause problems and which ones will not.False-negative test results can occur.

The lymph nodes, lobes, lobules, ducts, and other parts of the inside of the breast are also shown.Each breast also contains blood vessels and lymph vessels. The lymph vessels carry an almost colorless fluid called lymph. Lymph vessels lead to organs called lymph nodes. Lymph nodes are small bean-shaped structures that are found throughout the body. They filter substances in lymph and help fight infection and disease. Clusters of lymph nodes are found near the breast in the axilla (under the arm), above the collarbone, and in the chest.See
