Does stress cause breast cancer?

Breast cancer is a condition caused by genetic mutations that occur and cause breast cells to be overproduced. There are many causes of this condition, of which, about 5 to 7% are genetic and more than 90% are due to factors from the environment and lifestyle of the patient. Specifically:
Environment: According to recent studies, the environment has a lot of influence on our health. Some factors such as smoke, chemicals, microorganisms, X-rays, ultraviolet rays, ... are factors related to various types of cancer, including breast cancer. Lifestyle: Experts say that breast cancer is related to overweight, obesity, smoking habits and inactivity. The body's immunity: The body's immune system is also thought to be one of the causes of breast cancer. You can simply understand that if the immune system is healthy, the risk of cancer will be lower. On the contrary, when the immune system works poorly, the cells and malignant tumors will overcome their control and form diseases, including breast cancer. While breast cancer is also one of the most treatable cancers, once it has metastasized – that is, it has grown and spread – it can grow rapidly and become diverse. .

So “does stress cause breast cancer?” Previous research that Medical News Today covered suggests that chronic (long-term) stress exposure is a contributing factor to cancerous cell growth in breast cancer.
Now, a new study conducted by a team from the University of Basel and the University Hospital of Basel in Switzerland has discovered further evidence that stress can promote the spread of cancerous tumors breast,.
Research - which the team performed in a mouse model - has found that stress hormones aid in breast cancer metastasis. Scientists also claim that the stress hormone derivatives found in some anti-inflammatory treatments can actually "disarm" chemotherapy agents.
There are many theories about how stress may contribute to the risk of developing breast cancer as follows:
Continuous activation of the stress response and exposure to related hormones may promote promote the growth and spread of tumors. The immune system can play an important role in finding and eliminating cancer cells. But already chronic stress can make it harder for a person's immune system to perform these tasks. Prolonged stress can lead to inflammatory conditions that contribute to cancer risk. Thus, it can be seen that stress is one of the factors that cause breast cancer. Managing stress is key to reducing cancer risk.
