Chemotherapy is the most common treatment given during pregnancy. The drugs destroy cancer cells but also affect healthy cells.
The thought of having chemotherapy during pregnancy can seem frightening. It is natural to worry about the possible effects on the baby. But at the same time, you may feel you want to get on with treatment.
The results of research looking at babies whose mothers had chemotherapy after the first trimester are reassuring. There may be a small risk the baby will be born earlier or have a slightly lower birth weight. But there do not seem to be any other problems that are different to those of babies born to mothers who have not had chemotherapy. Their development compared with other children does not seem any different either.
Your doctor will avoid giving you certain chemotherapy drugs during pregnancy. This is because they are harmful to the baby. Or because there is not enough evidence to show that they are safe in pregnancy.
