is it bad to sleep with a bra on everynight?

I remember reading this article in a magazine…

A ‘Bra and breast cancer Study’ conducted in the United States, had revealed a significant link between bras and breast cancer that is three times greater than the link between cigarette smoking and lung cancer.

Their study also revealed that wearing a bra over 12 hours daily conferred a 113 fold increase in breast cancer incidence.

Because of the pressure bras apply to the breast, the lymphatic system is also affected. The lymphatic system consists of tiny, thin-walled vessels, which drain away toxins, cell debris, pathogens like bacteria, viruses and even cancer cells from the breast tissue. And since these vessels have no internal pressureby themselves, they are easily compressed by external pressure, for instance a bra, for instance causing congestion of the tissues. Therefore a tight bra would close the lymphatic pathway from the breast to the lymphatic nodes, causing fluid build-up, swelling, tenderness and cyst formation.

And I remember from when I was in college that Lymph nodes filter the lymphatic fluid and store special cells that can trap cancer cells or bacteria that are traveling through the body in the lymph fluid. So if you wear a bra to bed you may be restricting your lymph nodes in your breasts from filtering out all of the toxins and possible cancer cells that need to be filtered. So I would say its best to not wear your bra to bed.
