Although researchers are not sure why, breast feeding has been found to offer some protection against breast cancer. One study by Cancer Research UK found that for every extra year a woman breast fed in her life, her risk of developing the disease was reduced by around 4.5 percent. The study also found that there was a reduction in breast cancer risk by around 7 percent for each child born. The study concluded that if each child were breast fed for an extra six months around 1,000 cases of breast cancer could be prevented. Globally countries within which women breast feed for longer also have lower rates of breast cancer compared to developed countries with the shortest breast feeding period for children.
Treatments for breast cancer such as chemotherapy include
substances that can be passed to a baby during
breast feeding and can be harmful. It is therefore advisable
to stop breast feeding during treatment and for a period of
time afterwards depending on the treatment that an
individual has undergone.
Again, it is important that you fully discuss your options
with your doctor who will have a full understanding of
the treatments that you are undergoing and their
potential impact upon the health of your child.
