What Stress can make some serious diseases such as cancer harder to?

Chronic stress can weaken the immune system, making it less effective at detecting and attacking cancerous cells. It can also lead to behaviors such as poor diet, lack of exercise, and substance abuse, which can further increase cancer risk. Additionally, stress may promote inflammation and create a biological environment that facilitates tumor growth and metastasis. Together, these factors can complicate both the prevention and treatment of cancer.
