Should pregnancy be terminated if cancer is diagnosed?

No, terminating a pregnancy is not an inevitable or routine procedure simply because a woman is diagnosed with cancer. The final medical decision depends on a complex set of factors, including the type of cancer, its stage, how quickly it is spreading, the stage of the pregnancy, and the mother's wishes. Thanks to medical advancements, it is often possible to delay treatment or select treatment protocols that protect the fetus while the mother receives the necessary care for her condition [2].

Tumors during pregnancy are rare and vary between benign and malignant. Among the most prominent types of cancer that may be diagnosed in pregnant women are breast cancer, thyroid cancer, cervical cancer, lymphoma, and melanoma. It is important for a pregnant woman to realize that cancer itself rarely causes direct harm to the fetus, which allows the healthcare team to seek a delicate balance between treating the mother and maintaining the safety of her pregnancy [2].

Evaluating the Condition and Determining Treatment Options

When a cancer diagnosis is made during pregnancy, a multidisciplinary medical team begins a comprehensive evaluation. The primary goal is to determine if treatment can be delayed without endangering the mother's life. For example, in certain cases such as slow-growing cervical cancer discovered in its early stages during the first trimester, the medical team may suggest delaying therapeutic intervention until a later stage of pregnancy or even after delivery to reduce risks to the fetus [3].

However, if the cancer type is fast-growing or in advanced stages, delaying treatment may not be possible, which may necessitate difficult decisions regarding immediate intervention. In such cases, the benefits and risks of each treatment option must be discussed with complete clarity, including how the treatment will affect the mother, fetal health, and future fertility [3].

Safe Treatment Options and Precautions

Treatment options vary significantly based on the type and location of the cancer. For example, in cases of stage I cervical cancer diagnosed during the second or third trimester, surgical options such as cold knife conization or radical trachelectomy may be available—procedures aimed at removing the affected tissue while attempting to maintain the pregnancy [3].

Regarding chemotherapy, studies indicate that for certain types of cancer, specific drugs can be administered during the second or third trimester without causing direct harm to the fetus, although this may be associated with the potential for preterm birth or low birth weight infants. However, extreme caution must be exercised regarding other treatments; for instance, radiation therapy is considered highly harmful throughout fetal development and must be avoided during pregnancy, and some types of chemotherapy are not considered safe during the first trimester [3].

The Importance of Medical Planning and Follow-up

The treatment plan must be entirely customized for each individual case. There is no general rule that applies to everyone, which is why doctors focus on coordination between oncologists and obstetricians. It is always advised to ask about all possibilities, ranging from early delivery via cesarean section—which may allow the mother to begin subsequent radiation or chemotherapy treatments—to strategies for close monitoring.

Always remember that open communication with your medical team is the first and most important step toward making an informed decision that protects your health and future.
