What kind of impact does stress have on breast cancer?

In 2012, some research studies have shown that factors such as traumatic events and losses can alter immune system functions, and when immune functions are altered cancer cells may have an opportunity to get themselves established within one’s body. What has been shown is that it is not the fact that a major life crisis has occurred but instead how the individual reacted to this event and coped (or didn’t cope). Therefore, identifying ways to keep your stress level in check is wise.
