The symptoms of malignancy during pregnancy can vary widely depending on the type and location of the cancer. Common symptoms may include unusual lumps or masses, unexplained weight loss, persistent fatigue, or abnormal bleeding. However, some symptoms may overlap with normal pregnancy changes, making diagnosis challenging. For instance, breast changes are common in pregnancy, but a persistent lump should be evaluated further.

The workup for suspected malignancy during pregnancy involves a combination of clinical evaluation, imaging, and sometimes biopsy. Safe imaging techniques, such as ultrasound and MRI, are preferred to avoid radiation exposure to the fetus. Blood tests and tumor markers may also be used to aid in diagnosis. A biopsy, which involves taking a small tissue sample, may be necessary to confirm the diagnosis and determine the cancer type.

Treatment of cancer during pregnancy depends on the type and stage of the cancer, as well as the gestational age of the fetus. Options may include surgery, chemotherapy, and, in some cases, radiation therapy. Surgery is often considered safe during pregnancy, while chemotherapy may be used with caution, especially after the first trimester. Radiation is generally avoided due to potential risks to the fetus. The treatment plan is tailored to minimize harm to the fetus while effectively treating the cancer.

The prognosis for malignancy diagnosed during pregnancy varies based on the cancer type, stage at diagnosis, and treatment response. Early detection and appropriate treatment are crucial for improving outcomes. In some cases, pregnancy may delay diagnosis, potentially affecting prognosis. However, many women with cancer during pregnancy can have successful outcomes with careful management.

The exact cause of cancer during pregnancy is not well understood. It is believed to be similar to cancer in non-pregnant individuals, involving genetic mutations and environmental factors. Pregnancy itself does not cause cancer, but hormonal and immune changes during pregnancy may influence cancer growth and progression.

Cancer during pregnancy is relatively rare, occurring in approximately 1 in 1,000 pregnancies. The most common cancers diagnosed during pregnancy are breast cancer, cervical cancer, lymphoma, and melanoma. The incidence of cancer during pregnancy is expected to rise as more women delay childbearing to older ages, when cancer risk is higher.

The pathophysiology of cancer during pregnancy involves the same mechanisms as cancer in non-pregnant individuals, including uncontrolled cell growth and division. However, pregnancy-related hormonal changes and immune system adaptations may affect tumor behavior. For example, increased levels of estrogen and progesterone can influence hormone-sensitive cancers like breast cancer.

Preventing cancer during pregnancy involves general cancer prevention strategies, such as maintaining a healthy lifestyle, avoiding known carcinogens, and undergoing regular health screenings. Women planning pregnancy should discuss their cancer risk with their healthcare provider and consider appropriate screenings before conception.

Malignancy diagnosed during pregnancy is a complex condition requiring careful management to ensure the health of both mother and child. Early detection and a multidisciplinary approach to treatment are essential for optimizing outcomes. While cancer during pregnancy is rare, awareness and appropriate workup are crucial for timely diagnosis and intervention.

If you are pregnant and experiencing unusual symptoms such as persistent lumps, unexplained weight loss, or abnormal bleeding, it is important to discuss these with your healthcare provider. While these symptoms can be related to normal pregnancy changes, they may also indicate a more serious condition. Your healthcare provider can guide you through the necessary evaluations and discuss any concerns you may have about cancer during pregnancy.
