About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Ectopic Pregnancy

The uterus, or womb, is the place where a fetus grows during pregnancy. In an ectopic pregnancy, the fertilized egg grows in the wrong place outside the uterus. It usually occurs in the fallopian tubes. These tubes carry eggs from the ovaries to the uterus. Sometimes, an ectopic pregnancy can occur in the ovaries, abdominal cavity, or the lower part of the uterus (cervix).

Tumors and Pregnancy

Tumors during pregnancy are rare, but they can happen. Tumors can be either benign (not cancer) or malignant (cancer). The most common cancers in pregnancy include breast cancer, thyroid cancer, cervical cancer, lymphoma, and melanoma. Cancer itself rarely harms the fetus, and some cancer treatments are safe during pregnancy. You and your health care provider will work together to find the best treatment. Your choices will depend on how far along the pregnancy is, as well as the type, size, and stage of your cancer.
