Cancer and Stress
It is always a big pleasure to have an excuse to return to this topic. Repeat after me: Stress does not cause cancer. It actually seems that the converse should be true: Cancer causes stress. There have been numerous studies that should have laid these worries to rest, but newly diagnosed people continue to worry that they are somehow responsible for the cancer. Had they handled stress or anger or other negative feelings "better", cancer would not have happened. That is complete and total hogwash.
This particular article comes from BreastCancer.org. Although this is about breast cancer, the facts all hold for any kind of cancer. Here is the start and a link. If you ever have lingering worries about this, please read it:
No Link Between Stress, Breast Cancer Risk
Many women feel that stress and anxiety caused them to be diagnosed with breast cancer. Because there has been no clear proof of a link between stress and a higher risk of breast cancer, researchers in the United Kingdom conducted a large prospective study on the issue.
The results show no link between breast cancer risk and stress or difficult life events, including the loss of parents during childhood.
The study was published online on July 15, 2016 by the journal Breast Cancer Research. Read “Psychological stress, adverse life events and breast cancer incidence: a cohort investigation in 106,000 women in the United Kingdom.”
A prospective study follows a group of similar people who are different in terms of the factors being studied to see how the factors affect the rates of a certain outcome. A prospective study is considered stronger than a retrospective study. A retrospective study analyzes information that was collected before the study was designed.
In the study, the researchers looked at the records of 106,612 women 16 or older in the United Kingdom who were part of Breakthrough Generations Study, a study looking at the causes of breast cancer. The women joined the study between 2003 and 2012. None of the women had been diagnosed with breast cancer when they joined the study.
