In Pregnancy
Cancers found during or shortly after pregnancy appear at approximately the same rate as other cancers in women of a similar age. As a result, breast cancer is one of the more common cancers found during pregnancy, although it is still rare, because only about 1 in 1,000 pregnant women experience any sort of cancer.
Diagnosing a new cancer in a pregnant woman is difficult, in part because any symptoms are commonly assumed to be a normal discomfort associated with pregnancy. As a result, cancer is typically discovered at a somewhat later stage than average in many pregnant or recently pregnant women. Some imaging procedures, such as MRIs (magnetic resonance imaging), CT scans, ultrasounds, and mammograms with fetal shielding are considered safe during pregnancy; some others, such as PET scans are not.
Treatment is generally the same as for non-pregnant women. However, radiation is normally avoided during pregnancy, especially if the fetal dose might exceed 100 cGy. In some cases, some or all treatments are postponed until after birth if the cancer is diagnosed late in the pregnancy. Early deliveries to speed the start of treatment are not uncommon. Surgery is generally considered safe during pregnancy, but some other treatments, especially certain chemotherapy drugs given during the first trimester, increase the risk of birth defects and pregnancy loss (spontaneous abortions and stillbirths). Elective abortions are not required and do not improve the likelihood of the mother surviving or being cured.
Radiation treatments may interfere with the mother's ability to breastfeed her baby because it reduces the ability of that breast to produce milk and increases the risk of mastitis. Also, when chemotherapy is being given after birth, many of the drugs pass through breast milk to the baby, which could harm the baby.

Famous quotes containing the word pregnancy:
“If pregnancy were a book they would cut the last two chapters.”
—Nora Ephron (20th century)
“Back in the days when men were hunters and chestbeaters and women spent their whole lives worrying about pregnancy or dying in childbirth, they often had to be taken against their will. Men complained that women were cold, unresponsive, frigid.... They wanted their women wanton. They wanted their women wild. Now women were finally learning to be wanton and wild—and what happened? The men wilted.”
—Erica Jong (b. 1942)
