Results from a study conducted by the American Cancer Society indicate that about 40% of cancer cases can be prevented by changing lifestyle habits. The Cancer Journal for Clinicians notes that, according to researchers, "about 40% of all cancer cases and roughly half of all cancer-related deaths are due to potentially modifiable risk factors. The occurrence of cancer and early mortality can be significantly reduced through the widespread use of known prevention methods."
Scientists recommend primarily quitting smoking, as this can greatly reduce the chances of developing lung, throat, bronchial, and esophageal cancers. The second habit to eliminate is alcohol consumption, as it can help prevent cancers of the oral cavity and pharynx. Another detrimental habit is failing to maintain a healthy weight, as being overweight or obese may lead to gastric, liver, colon, and rectal cancers.
According to researchers, sunscreen should be used to reduce the risk of skin cancer. Lastly, oncologists urge people to avoid a sedentary lifestyle, as inactivity increases the likelihood of stomach, esophageal, and colon cancers. Other factors contributing to cancer include passive smoking, inadequate dietary intake of fruits and vegetables, consumption of raw unprocessed meats, and lack of vaccination against human papillomavirus (HPV) and hepatitis B.
