It is a well established fact that tobacco is one of the major causes of cancer. This means it is important to avoid smoking and chewing tobacco as it can lead to serious health complications. Likewise, avoid other important risk factors like too much exposure to sunlight and avoid consumption of too much alcohol.
Finally, regular cancer screenings like mammography and breast examination in the case of breast cancer or colonoscopy in case of colon cancer may enable you to detect the cancer in a very early stage. This will certainly help in treating the illness almost completely.
