Breast cancer in pregnant women is common and treatable with surgery or chemotherapy. A normal-length pregnancy should be the aim to avoid premature birth. Chemotherapy can be given as per standard guidelines, but radiation therapy is not advised due to fetal shielding concerns.
A study found that Hispanic women living in the US for less than 10 years have a 3.4% frequency of preterm birth, while those living for 10 or more years have twice the risk and 7.4% frequency. This suggests environmental factors may contribute to preterm birth and are potentially modifiable.
Blood cancers in pregnancy can lead to increased risk of blood clots and health complications for the mother. Termination is recommended at early stages, while cancer therapy is possible later. Progesterone-only contraceptives are considered safe for patients in long-term remission.
A study found that pregnant women with a prior cesarean section often choose the delivery method preferred by their doctor, regardless of their own knowledge on the risks and benefits. The majority of these women opt for an elective repeat cesarean over a trial of labor, despite its higher success rate. Lack of education and provider p...
Researchers discuss management of cervical cancer during pregnancy, focusing on tumour size, nodal staging, term of pregnancy, and histological subtype. Chemotherapy can be used in the second or third trimester to increase chances of fetal preservation, but carries risks of premature birth and low birthweight.
