A new study suggests women with risk of breast cancer should not have irregular sleeping habits especially working late night shifts.
The findings of a recent study on mice have revealed breast cancer in women may be linked to irregular sleeping habits. According to the study irregular sleeping patterns "unequivocally lead to cancer in tests on mice.

The findings published in Current Biology have shed light on the damages late night shifts have on the health of female workers. Especially women with a family history of breast cancer should never be working on late night shifts but further tests are required.
One of the arguments for the theory is the biological clock or body internal rhythm is disturbed which leads to an increase in diseases. However other factors such as social class, activity levels or the amount of vitamin D consumption also determine whether the person will develop cancer.
In the study mice with a delayed body clock by 12 hours every week for a year were more prone to developing breast cancer than mice without a disturbing sleeping habit. After 50 weeks the mice developed tumors but starting the sleep disturbance regularly the tumors appeared even eight weeks earlier.
The study is the first of its kind which states exposure to light and dark phases develop breast cancer. The study has given definitive experimental proof to support its theory that light phases aid in the rapid development of breast cancer. If the theory is true in fact then it may lead to helping women at risk of breast cancer to avoid working late and better their life style.

However if the theory about light phases is true then the radiation involved in the screening of breast cancer may also be leading to development of breast cancer.
