Cancer cells usually originate from normal cells when the DNA in their nucleus is damaged. Some types of cancer can be hereditary but most types are not inherited. Some lifestyle choices can lead to an increased risk of cancer. This article looks at some common causes of cancer and how the risk of cancer can be decreased by avoiding such causes.
Smoking and Tobacco
Smoking tobacco has been identified as a leading cause of cancer. People that use tobacco or who are exposed to second hand smoke have an increased risk of cancer because the smoke contains chemicals that can damage DNA. According to the American Cancer Society, tobacco smoke contains 70 known carcinogens. There is no safe level of tobacco use and those that use tobacco products are advised to quit. Tobacco is known to cause cancer in the lungs, mouth, esophagus, stomach, throat and more remote areas of the body.
Diet and Physical Activity
The American Cancer Society also stresses the importance of maintaining a healthy body weight, being physically active, and having a plant based diet. Studies have tested how certain nutrients can increase or decrease the risk of cancer. From the studies it is evident that having a poor diet and not being active can lead to an increased risk of cancer. Staying physically active and making healthier food choices can reduce your cancer risk. To decrease the odds of cancer, avoid excessive alcohol and try to maintain a healthy body weight.
Sun and other types of radiation
The sun, tanning booths and sun lamps give off UV radiation that is known to cause early aging of the skin and can lead to skin cancer. The amount of time spent in the sun, especially between the mid-morning and late afternoon, should be reduced. Wearing protective clothing and using sunscreen that contains sun protection factor above 15 can decrease the risk of cancer. Other artificial sources of UV rays including welding and phototherapy pose a similar threat. The American Cancer society states that X-rays and gamma rays, when exposed to high doses, are cancer causing agents.
