Which of the following factor(s) contribute to more than half of all cancer diagnoses every year?
smoking and diet
The following factors contribute to more than half of all cancer diagnoses every year:
1. Tobacco use: Tobacco use is the leading cause of preventable deaths worldwide, and it is estimated that one-third of all cancers are related to tobacco use. Smoking can cause cancer in many parts of the body, including the lungs, throat, mouth, bladder, pancreas, liver, and colorectal area.
2. Age: Cancer is more common in older adults. As we age, the DNA in our cells can become damaged and accumulate over time, leading to increased risk of cancer.
3. Genetics: Some cancers may be hereditary. This means that a person’s risk of developing certain types of cancer is passed down from generation to generation. BRCA1 and BRCA2 gene mutations, for example, are associated with an increased risk of breast and ovarian cancer.
4. Poor diet: A diet high in processed and red meats, saturated and trans fats, and low in fruits, vegetables, and fiber may increase the risk of certain types of cancer.
5. Sedentary lifestyle: Lack of physical activity and a sedentary lifestyle have been associated with increased risk of cancer, particularly of the colon, breast, and endometrium.
However, it is important to note that cancer is a complex disease with many contributing factors, and it is not always possible to determine the exact cause of any individual case.
