A multinational study has debunked the myth that depression and anxiety significantly increase the risk of most types of cancer. Although a slight elevation in risk was observed for lung and smoking-related cancers among individuals with depression or anxiety, this effect was largely mitigated after adjusting for lifestyle factors.
Recent research has provided evidence that depression and anxiety do not significantly raise the risk of most types of cancer. However, they do appear to be associated with a slightly higher risk of lung and smoking-related cancers, which becomes considerably lower when accounting for factors like smoking and alcohol consumption.
While it has been hypothesized that depression and anxiety might increase the risk of cancer by influencing a person’s health behaviors or inducing biological effects that promote cancer development, previous studies have yielded mixed results. In this new analysis, researchers examined data from multiple studies across the Netherlands, the United Kingdom, Norway, and Canada, involving over 300,000 adults, to gain better clarity on the issue.
The results of the analysis showed no meaningful connections between depression or anxiety and overall, breast, prostate, colorectal, and alcohol-related cancers over a period of up to 26 years. However, there was a 6% higher risk of developing lung cancer and smoking-related cancers associated with depression or anxiety. Nevertheless, this risk significantly diminished once other cancer-related risk factors like smoking, alcohol use, and body mass index were considered. Consequently, this study highlights the importance of addressing tobacco smoking and other unhealthy behaviors that might arise due to anxiety or depression.
Dr. Lonneke A. van Tuijl, the lead researcher, emphasized that these findings may bring relief to cancer patients who previously believed their condition was caused by anxiety or depression. Nonetheless, further research is needed to better understand the exact relationship between depression, anxiety, health behaviors, and lung cancer.

Frequently Asked Questions (FAQs) about Cancer risk
Q: Is there a link between depression and anxiety with an increased risk of cancer?
A: According to a multinational study, depression and anxiety do not significantly increase the risk of most types of cancer. However, there is a slight elevation in the risk of lung and smoking-related cancers among those with depression or anxiety. This risk is largely mitigated when lifestyle factors, such as smoking and alcohol use, are taken into account.
Q: What does recent research indicate about the relationship between mental health and cancer risk?
A: Recent research suggests that depression and anxiety are not significantly associated with a higher risk of most types of cancer. However, there appears to be a marginally higher risk of lung and smoking-related cancers for individuals with depression or anxiety. This risk is reduced considerably after adjusting for factors like smoking and alcohol consumption.
Q: How was the link between mental health and cancer risk examined in this study?
A: The researchers conducted an analysis using data from the international Psychosocial Factors and Cancer Incidence consortium. This consortium comprised information from 18 prospective study groups involving over 300,000 adults from different countries, including the Netherlands, the United Kingdom, Norway, and Canada.
Q: Were any specific types of cancer found to be linked to depression and anxiety?
A: The study did not find any meaningful associations between depression or anxiety and overall, breast, prostate, colorectal, and alcohol-related cancers. However, there was a 6% higher risk of developing lung cancer and smoking-related cancers for individuals with depression or anxiety. This risk was significantly reduced after accounting for other cancer-related risk factors, such as smoking, alcohol use, and body mass index.
Q: What is the significance of these findings for cancer patients?
A: The study’s findings may provide relief to cancer patients who previously believed their diagnosis was attributed to past anxiety or depression. However, it is essential to continue researching to gain a better understanding of how depression, anxiety, health behaviors, and lung cancer are related.
Q: How has the theoretical link between mental health and cancer been explained in previous studies?
A: Experts have theorized that depression and anxiety might elevate cancer risk by affecting a person’s health-related behaviors or inducing biological effects on the body that encourage cancer development. However, prior research has produced mixed results, with some studies showing a link between depression, anxiety, and cancer incidence and others indicating little or no correlation.

I’m impressed by the research analysis done here, and it’s such a relief to see that depression n anxiety aren’t hugely linked to cancer risk overall. But it’s intresting to note the connection with lung n smokin cancers. More research needed 2 find out the whys!
gr8! i was so scard that my anxiety cud cause cancer but this study say no big deal for most types! thx for sharing this, it’s a reli fashinating read! we should tak care of our health tho, ya know, n stay positive!
wow this study say no big link btwn depression n cancer risk, which is gr8 news for us strugglin with mental health! but sumtiny to wotch out 4: smokin relatd cancers still got slight risk if u hav depression/anxieti. better quit that smoke!
