Pregnancy cancer is a serious problem for anyone facing this challenge. Evaluating several aspects before starting treatment is essential.

Pregnancy-associated cancer is any malignant disease that doctors diagnose during pregnancy or up to 1 year after birth. Some experts reduce the period from 1 year to 6 months.

The effect of pregnancy on the disease

Although there are opposing views on this subject, the idea that pregnancy does not change the natural course of the disease is becoming increasingly relevant. The mechanism by which the mother’s body allows the growth of a foreign body may suggest a certain permissiveness of the immune system.

This affinity for tumor development is a constant topic of research because it could be a key to planning safe treatments. Some researchers believe that pregnancy encourages the development of cancer.

Tumor effects on pregnancy

There does not appear to be a significant effect on the fetus or on the progress of the pregnancy. The rate of miscarriages and premature births is similar and only in certain types of cancer – leukemia, cervical cancer – complications multiply (infections, bleeding or difficulty in vaginal birth).

Therefore, it is important to know that the fetus is rarely affected. Statistics indicate that fetal problems occur to a greater extent in melanomas.

Breastfeeding and cancer

Most doctors recommend that women who have given birth and are undergoing treatment for cancer stop breastfeeding. In the case of breast cancer, if surgery is considered, stopping breastfeeding will help reduce blood flow to the breasts, which will reduce them and facilitate surgery.

Many of the medicines used to treat cancer can be transferred to breast milk. Therefore, experts do not recommend breastfeeding if the patient is receiving chemotherapy, hormone therapy or targeted therapy.


Cancer in pregnancy is a very serious situation, which requires an evaluation from different perspectives.

It is possible to cure cancer, despite the fact that you are pregnant, without adversely affecting the fetus. However, it is a delicate situation and you need to understand that it is not easy to deal with.

Ask your doctor about all available options. It will help you understand which is the most appropriate treatment for you.
