What kind of impact does stress have on breast cancer?

Very Important: There is no link between stress and development of breast cancer. Stress can adversely affect a womans' ability to undergo complex and lengthy breast cancer treatment- this in turn can lead to inferior results. Patients without psychosocial support for stress can develop problems such as ptsd, strained spousal relationships, sexual problems, etc.

Stress can cause it.: Very recently there was a study that identified stress as an independent cause of a type of breast cancer-called triple negativethis type is very aggressive even at a small size. It means that this type does not have hormone receptors for estrogen and Progesterone also is negative for her2 receptors. This type accounts for about 15% of all breast cancer. We don't have targeted tx yet.

Doesn't help: There is not clear evidence, but decreasing your stress has to be good thing.

Stress and cancer: No strong evidence that stress causes any cancer. However , those who attempt to manage their stress with risky behaviors such as smoking or drinking alcohol- can increase the risk to have cancer related to their behavior. Also, from experimental studies- it's suggested that stress can affect a tumor’s ability to grow and spread. Emotional and social support can help cope with psychological stress.
