1. Age. Most cancers attack over the age of 45 years. Not that you are immune if you are under that age, but this means that the more you age, the more you have to improve the factors that can harm your body's health.

2. Bad habits: smoking (increases the risk of lung cancer), excessive alcohol consumption has been linked to cancer, using illegal drugs also plays a role in several types of cancer.

3. Geographic location. Industrial countries have a higher risk of certain cancers than developing countries. However, it is believed that environmental factors such as lifestyle, culture, diet, water and air quality play a role in causing cancer in relation to geographic areas.

4. Diet. High fat intake is associated with cancers of the breast, colon, ovary, kidney, lung, and endometrium; Low fiber intake is associated with a higher risk of colon cancer; increased intake of phytoestrogens can be associated with lower risk of breast cancer.

5. High estrogen levels can be a sign of an increased risk of reproductive cancer, such as the breast and endometrium.

6. Lack of exercise. The time spent mostly on the seat is associated with an increased risk of various types of cancer. Fortunately, being more active is an improvement that can be easily done by most people.

7. Genetics. Most people think that genetics is a major risk factor for cancer, but family history and DNA are just one factor. New research shows that lifestyle and diet may play a role in changing cancer genes. So, this factor can still be managed.

8. Income. Low income is associated with a higher risk of gastric cancer, lung cancer (in men), cervical cancer (in women), and cancers of the mouth, pharynx, larynx and esophagus; whereas higher income is associated with a higher risk of skin cancer, breast cancer, prostate cancer and colon cancer (in men). Who would have thought that being a middle class was a lucky thing?
