Q. It’s been almost three years since I had a breast cancer operation, which was followed by chemotherapy. I’m now considering having another child, but my husband is concerned that my history of cancer might affect the pregnancy. What possible dangers lie ahead if we proceed?
A. Since your question may be interpreted in two ways, I’ll try to answer both questions for you. The surgery has had no effect on your ability to become pregnant. Even with the history that you had-a course of chemotherapy (anti-cancer medication) after the operation-your hormonal functions now may be considered normal, and the chances of becoming pregnant are the same as before the operation.
The advisability of becoming pregnant is, however, another important question.
In pregnancy, the production and flow of female hormones change considerably, and their effect on the breast, and its potential to develop another cancer, change as well.
While some studies show an improved outlook during pregnancy, the risk of developing cancer in the other breast may be increased. The possibility of recurrence depends upon a number of important factors-the size of your first tumor, any signs of spread, the length of time between the development of the cancer and its treatment, and the kind of tumor are all considerations, and they’re difficult for me to evaluate without more information.
It’s important to know that if a new cancer is discovered while you’re pregnant, immediate and intense therapy will be necessary.
Depending upon the stage of your pregnancy, this would expose the fetus to many risks. However, many women in your situation carry the pregnancy to term without harm to the baby.
While there are varying opinions among the experts, it’s generally advisable to wait at least three years after a course of breast cancer treatment before trying to conceive.
Since there are many factors to take into consideration, you would be well-advised to sit down with your physician and your husband for a full discussion. It’s the very best way to reassure yourself about the many concerns you’re experiencing and to arrive at the best decision for all concerned.
