50% of all cancers are due to environmental factors. For this reason, cancer is a preventable disease that can be completely cured with early diagnosis. Living healthy, quitting smoking, eating healthy, doing sports, reducing alcohol consumption, getting Hepatitis B vaccine and HPV vaccine, protecting from sun, staying at ideal weight are the most important measures that can be taken to prevent cancer.

Quit smoking: Smoking alone is responsible for 30% of cancer-related life losses. 90% of the most common lung cancer is associated with smoking. Smoking is also a major cause of bladder, mouth, esophagus, throat cancer and many other cancers.

Physical activity reduces both the risk of cancer and the possibility of recurrence of the disease after cancer treatment.

Alcohol creates a risk for many cancers, especially liver, head and neck, and breast cancer.

Sun rays are an important factor for skin cancer. The use of sunscreen should not be neglected.

Obesity is directly related to many cancers, especially breast and pancreatic cancer.

Hepatitis B vaccine against liver cancer and HPV vaccine against cervical cancer should be administered.

Breast cancer, cervical cancer, prostate cancer and colon cancer are cancers for which early diagnosis is possible with screening tests. Early diagnosis can be achieved by mammography after the age of 40 for women, colonoscopy after the age of 45 for both men and women, and colon cancer screening. Again, lung cancer can be detected in the early period with low-dose lung tomography performed according to the risk group in people who smoke. Regardless, even if cancer is diagnosed, hopelessness should be avoided and it should be remembered that there are many treatment options.
