Desire for a child and breast cancer
Abstract:
About 10% of breast cancers occur in women who are younger than 40 years of age. For many of them, the breast cancer diagnosis will occur when they are still planning pregnancy. Most breast cancers are diagnosed at an early stage of the disease, i.e. stage I or II, which is associated with a high survival rate (5 years-survival ranging between 97% and 79% respectively) (1). Many of these patients will use adjuvant endocrine therapy. This treatment has no direct impact on their fertility, but postpones a possible pregnancy, since pregnancy is contra-indicated during Tamoxifen treatment. On the other hand, chemotherapy increases the risk of premature ovarian failure, of early menopause, and of definitive sterility. This may result in an increased risk of depression and impaired quality of life. Furthermore, those women who remain fertile will often be advised to avoid pregnancy in the near future, in order to ensure the absence of breast cancer recurrence. Nevertheless, fertility decreases with age. Possible strategies, which permit optimal treatment of breast cancer and maintain the possibility of pregnancy, should be systematically discussed with the patient as soon as possible during treatment planning (2). Gynecologists and surgeons should encourage such patients to participate in multi-center studies evaluating strategies to preserve their fertility. Life continues after cancer; the prospect of pregnancy and child birth are part of a positive project.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
