Cancer is a significant global health challenge, with millions of new cases diagnosed each year. In India alone, over 1.5 million new cancer cases are reported annually, affecting individuals across various age groups. Early diagnosis plays a critical role in successful treatment outcomes, but when cancer is diagnosed during pregnancy, it presents unique challenges, intertwining the complexities of oncology and obstetrics. This unusual but complicated condition needs special care in order to safeguard the mother and the growing infant.
Dr. Manish Kumar shares, “Balancing cancer treatment and pregnancy is a sensitive process. With effective strategies, we can safeguard both maternal health and fetal growth.

Let’s explore the hurdles in diagnosing cancer during pregnancy.
Diagnosis Challenges During Pregnancy
- Symptom Overlap:
Pregnancy and cancer share symptoms like fatigue, nausea, and breast changes, making it difficult to distinguish between the two.
- Imaging Limitations:
Certain diagnostic tools, such as CT scans and X-rays, involve radiation, which can be harmful to the fetus. This limits their application during pregnancy.
- Biopsy Concerns:
Invasive tests such as biopsies pose risks during pregnancy, causing possible delays in diagnosis.
- Hormonal Influences:
Changes brought about by pregnancy in hormones may influence tumor markers, making test results harder to interpret.
- Delayed Detection:
Due to these challenges, cancers are often diagnosed at more advanced stages during pregnancy, impacting treatment options.
What Are the Common Cancers Seen During Pregnancy?
Although cancer during pregnancy is rare, some types are more commonly diagnosed due to their prevalence among women of childbearing age. Breast cancer is the most frequently diagnosed cancer during pregnancy, followed by cervical cancer, thyroid cancer, Hodgkin’s lymphoma, and melanoma.
These cancers often present unique diagnostic and treatment challenges because their symptoms may overlap with normal pregnancy changes. Early detection and a multidisciplinary approach are key to ensuring the best outcomes for both mother and baby.
Curious about how cancer treatments work when you’re expecting? Here’s what you need to understand before making any decisions.
Treatment Options and Considerations
Navigating cancer treatment during pregnancy requires careful planning to protect both mother and baby. “Each treatment option is evaluated based on the type and stage of cancer, as well as the trimester of pregnancy,” explains Dr. Manish Kumar, an eminent cancer specialist in Bangalore.
- Surgery:
Surgery is often the safest option during pregnancy, especially in the second trimester. It removes tumors with minimal risk to the growing fetus.
- Chemotherapy:
Chemotherapy is generally avoided during the first trimester due to the risks of birth defects. However, certain chemotherapy drugs are considered safe during the second and third trimesters under close medical supervision.
- Radiation Therapy:
Radiation is generally delayed until after birth due to possible harm to the fetus. In exceptional and serious situations, it can be given with specialized shielding methods to reduce fetal exposure.
- Targeted Therapy:
There is limited evidence on the safety of targeted therapies during pregnancy. These are generally avoided unless the mother’s life is in extreme danger and no alternative, safer treatment is possible.
- Hormone Therapy:
Hormone therapies are generally avoided during pregnancy due to their potential to affect fetal development negatively. These treatments are usually postponed until after childbirth.
Worried about how cancer or its treatment might affect your baby? Here’s what medical science says about it.
Impact on the Baby
Cancer itself rarely directly affects the growing fetus because most cancers don’t pass the placental barrier. Yet treatments necessary to control cancer during pregnancy—particularly during the first trimester—pose possible risks. This is the most vulnerable time for organ growth, and the introduction of specific treatments during this period can create issues like birth defects or miscarriage.
If it is treated after the first trimester, the risk to the baby is much less. Chemotherapy during the second and third trimesters has been proven to be quite safe, though it increases preterm labor slightly. Prematurely born babies could experience difficulties such as low birth weight or slight delays in their development, but with advanced neonatal care, most babies recover nicely and hit good growth milestones.
It is critical that the mother’s healthcare providers, oncologists, obstetricians, and pediatricians coordinate during the pregnancy. Such coordination provides ongoing monitoring of the baby’s growth and facilitates timely intervention if any issues arise.
Delivery and Postpartum Care
The delivery technique for pregnant cancer patients is then carefully individualized according to cancer type and stage, treatments provided during pregnancy, and fetal condition. Vaginal delivery continues to be an acceptable choice for most patients in most instances. A cesarean section might be indicated when the cancer itself or its therapy has produced some complications or immediate postpartum treatments are urgently required.
Delivery timing is also an important consideration. Physicians can strive to extend the pregnancy until the infant is fully developed, but in certain circumstances, early delivery will be unavoidable in order to initiate or resume life-saving cancer therapy. In the case of expected preterm delivery, advanced care for newborns is provided to care for the infant shortly after birth.
Postpartum care is aimed at recovery from childbirth as well as resuming or starting cancer treatment. Mothers might have to continue chemotherapy, radiation, or other forms of therapy shortly after giving birth. Decisions on breastfeeding are also reviewed in relation to the safety of continued therapies. Breastfeeding is promoted where feasible, but some medications necessitate temporary or permanent stopping of breastfeeding to safeguard the infant.
Frequently Asked Questions
Can I receive chemotherapy while pregnant?
Some chemotherapy medications are safe in the second and third trimesters. Nevertheless, it is avoided in the first trimester to minimize risks to the baby.
Will cancer treatment harm my unborn baby?
Some treatments may pose risks, especially during the early stages of pregnancy. Treatment plans are carefully customized to minimize any potential harm to the unborn baby.
Is it safe to continue the pregnancy?
In the majority of situations, it is safe to continue the pregnancy with intensive medical monitoring. Decisions are made depending on the type and stage of cancer and options for treatment.
What if I need radiation therapy?
Radiation therapy is typically delayed until after giving birth because it poses risk to the unborn child. In exceptional circumstances where it is unavoidable, shielding methods specifically designed for babies are employed.
Can cancer and pregnancy occur together?
Yes, though uncommon, cancer and pregnancy may coexist. With good medical management, most women are able to cope with both.
Are there risks of preterm birth associated with cancer treatment during pregnancy?
Yes, treatments such as chemotherapy may pose a risk of preterm labor. Regular monitoring and planned care can decrease this risk.
