We all know that certain activities and habits such as smoking, drinking, and overeating can elevate the risk of cancer. However, there are numerous everyday activities that we engage in without realizing that they can also contribute to our susceptibility to cancer. Cancer is the second leading cause of death in the United States, just after heart disease. It is crucial to understand the risk factors and take steps to protect ourselves. In this article, we will explore 38 everyday activities that have been identified as potential contributors to cancer.

38 Everyday Things That Are Linked to Cancer

Cancer is a threat that seems to be growing every single year. There are many seemingly everyday things – activities, habits, and situations – that are linked to an increased risk of cancer. Thankfully, knowing what these are is the first step to taking control and decreasing your risk.

1. Increased sun exposure

While sunlight can be enjoyable, prolonged exposure to harmful ultraviolet (UV) rays can damage the skin and lead to skin cancer. It is essential to wear sunscreen with an SPF of 30 or higher, avoid peak UV radiation hours, and utilize protective clothing when spending time outdoors. (1)

2. Fake tanning

Indoor tanning, including tanning beds, can be as dangerous as sun exposure. Studies have shown that even a single session in a tanning bed can increase the risk of melanoma by 20%. Self-tanning lotions or sunless tanning booths are safer alternatives.

3. Frequent flying

Individuals who frequently travel by air, such as flight attendants and pilots, have a higher risk of various cancers due to exposure to cosmic ionizing radiation at higher altitudes. However, occasional flyers are unlikely to be exposed to significant levels of radiation. (2)

4. Smoking

Cigarette smoke contains over 4,800 toxic substances, including 70 carcinogens. Smoking significantly increases the risk of lung cancer, as well as various other types of cancer. Quitting smoking can dramatically reduce the risk of developing smoking-related diseases. 

5. Excessive alcohol consumption

Consistent and heavy alcohol consumption has been linked to an increased risk of cancers such as breast, liver, and esophageal cancer. Moderation is key to minimize the impact of alcohol on your health.
