Forty weeks can seem like a lifetime to an expectant mother. To pass the time, many mothers-to-be concentrate on picking a name and preparing their home for the baby. But what happens when cancer is thrown into the mix? As if becoming a new parent isn\u2019t stressful enough, now you are dealing with cancer treatments and everything that comes with it.\nDeveloping cancer during pregnancy is rare \u2013 only one out of 1,000 pregnancies is diagnosed each year. If you are diagnosed with cancer while pregnant, treatment options are available if you and your oncologists decide treatment during pregnancy is right for you. Cancer during pregnancy often can be managed, and you can deliver a healthy baby. The disease rarely affects the baby while in utero.\nCommon Cancer Diagnosis During Pregnancy\nThe most common cancers diagnosed during pregnancy include:\n\nBreast cancer\nCervical cancer\nHodgkin lymphoma\nMelanoma\nNon-Hodgkin lymphoma\nThyroid cancer\nGestational trophoblastic tumor\n\nCancer Treatment Options\nYour health care team can include your obstetric provider, oncologists, and maternal-fetal medicine (MFM) specialists. With you and your unborn baby\u2019s safety in mind, your oncologists will work closely with MFM specialists and consider a number of factors before recommending a treatment plan. They will evaluate the type of cancer, baby\u2019s gestational age, and your decision to be treated or not treated during pregnancy.\nTypes of cancer treatments used during pregnancy may include:\n\nChemotherapy \u2013 If administered during the second or third trimester, some chemotherapy drugs have been found to not harm the fetus.\nSurgery \u2013 The safest of the three main types of cancer treatment for pregnant women, surgery is preferred over chemotherapy and radiation.\n\n\nRadiation \u2013 Radiation is rarely used, even during the second and third trimesters, because radiation may harm the baby.\n\nGestational age is a major factor in treating cancer during pregnancy.\nDuring the first trimester, or first three months, treatments may be more likely to affect the baby\u2019s development. Typically oncologists delay treatment until the second or third trimester.\nMost importantly, you have options. Although more women are choosing to be treated for their cancer during pregnancy, oncologists are still learning how therapies affect mother and child. And many mothers choose to wait until after the baby is born to be treated.\nMaternal-fetal medicine specialists can help to put mom and baby\u2019s risks and benefits of treatment options, and timing during pregnancy, into perspective. Your health care team will factor your wishes into your treatment plan, so it is best to openly discuss your choices to help ensure you and your baby receive the most appropriate care for your situation.\nTo learn more about cancer and cancer treatments during pregnancy, get in touch with an expert with the UPMC Hillman Cancer Center.
