Research into a collection of studies has revealed that women who have suffered from breast cancer in the past would not face an increased risk of death from the disease should they choose to have children.
A collection of 14 pieces of research are to be presented at the European Breast Cancer Conference in Barcelona which have been scrutinised to provide clearer advice to women.
Dr Caitlin Palframan, spokeswoman for Breakthrough Breast Cancer, commented: "We still don't fully understand whether pregnancy after breast cancer can affect the chances of surviving the disease so research like this is key, helping to add to our knowledge in this area."
The doctor added that having as much information as possible is key for women who have suffered from the condition.
A mixture of some 20,000 women, all of whom had a history of the illness and some of whom were pregnant, were compared in the trials which took place between 1070 and 2009 in order to compare survival rates from the cancer.
