EXPERTS say they have now found that it is safe for women with the most common form of breast cancer to become pregnant.
Those diagnosed with oestrogen receptor positive breast cancer -- which accounts for 80pc of cases -- can become pregnant without worrying it will increase their chances of the disease returning, research suggests.
Doctors had feared that pregnancy can boost levels of oestrogen in the body and cause the cancer to come back.
The new findings, presented at the European Breast Cancer Conference in Vienna, suggest it is safe for women to fall pregnant even within the first two years after diagnosis.
Furthermore, the study found that patients who become pregnant appear to survive longer than those who do not, although further research is needed in this area.
