Cancer Prevention

Cancer Prevention is the topic of preventing the onset of cancer in people, and is considered a facet of oncology. The aims of cancer prevention are to reduce the incidence, morbidity, and mortality of cancer. Potential cancer-causing substances are called carcinogens. The prevention of cancer involves reducing exposure to carcinogens and modifying lifestyle factors that increase cancer risk, such as quitting smoking, following a healthy diet, avoiding excessive alcohol intake, protecting against sun exposure, maintaining a healthy weight, and exercising regularly, as well as cancer screening.

Cancer Prevention through Lifestyle Modifications

Quitting smoking and avoidance of secondhand smoke is a critical step. Smoking is the leading cause of preventable cancer deaths. Exposure to secondhand smoke can also increase the risk of lung cancer and other health conditions. Avoiding tobacco smoke is essential for cancer prevention.

A healthy diet is associated with a lower risk of several types of cancer. Studies have shown that eating plenty of fruits and vegetables is protective against cancer development. A healthy diet should include minimally processed foods and limited intake of red and processed meats. Dietary guidelines recommend limiting sugar intake and choosing whole grains over refined grains to maintain a healthy weight and reduce the risk of obesity, which is a risk factor for several types of cancer.
