  • Hodgkin lymphoma
  • Non-Hodgkin lymphoma
  • Melanoma
  • Gestational trophoblastic tumor

What happens if cancer is discovered during pregnancy?
Doctors and patients have a lot to consider when planning next steps after cancer diagnosis. Important questions like where is the cancer located, how far along is the pregnancy and what is the stage of cancer, all need to be explored. It’s likely that a team of oncologists and other doctors will work together to find the best methods for keeping the mother and fetus safe.

A medical oncologist, surgical oncologist, radiation oncologist, and pediatric oncologist are doctors who specialize in cancer treatment.

If cancer is discovered during pregnancy or any other time of life, it’s good to have a support system of reliable people. Being surrounded with positive people that can attend doctor’s appointments or act as a listening ear can help tremendously when battling cancer.

What are common cancer treatments available during pregnancy?

  • Surgery is an option when a tumor needs to be removed from healthy tissue. There is anesthesia used during surgery that could present some risks for the developing fetus. The anesthesiologist, surgeon and high-risk obstetrician will work together to decide the safest drugs for both the mother and fetus.
  • Chemotherapy is the use of drugs to wipe out cancer cells. The drugs usually stop the cancer cells' from growing and dividing. There is a chance of harm to the developing fetus whenever chemotherapy is used, but particularly in the first three months of pregnancy, when vital organs are still developing. The risk of harm to the mother and fetus depend on the drug and the stage of pregnancy.
  • Radiation therapy is the use of high-energy x-rays to wipe out cancer cells. The risks to the developing fetus depend on the dose of radiation, the area of the body being treated and the stage of pregnancy.
