Morning sickness may actually be a good thing.

Well, maybe not a good thing, but an indicator of a good thing. According to new research, nausea during pregnancy may mean a 30 percent reduced chance of developing breast cancer.
The study of 3,000 women found that those who got sick during pregnancy had a 30 percent reduced chance of developing breast cancer than the women who were sick-free.
The belief by researchers is that this may be due to the changing hormone levels that affect breast tissue while triggering the nausea. It’s no cure, but it could help us understand what biological factors effect woman’s risk for the disease.
