  • Preventing Cancer: How do you protect yourself from 200 diseases? Kathy Redmond, Editor, Cancer World Magazine
  • What are cancers?
  • Cancer types • Common – Lung, prostate, breast and colorectal • Rare – About a quarter of all cancers • Solid tumours • Blood and lymphatic system tumours
  • Breast cancer subtypes based on hormone receptor and HER-2 expression levels and Ki-67 staining.Abbreviations: ER, estrogen receptor; HER-2, human epidermal growth factor receptor 2; PR, progesterone receptor. Hortobagyi G N The Oncologist 2012;17:577-584 ©2012 by AlphaMed Press

  • About one third of all cancers can be prevented
  • European Code Against Cancer 1) Do not smoke; if you smoke, stop doing so. If you fail to stop, do not smoke in the presence of non-smokers. 2) Avoid Obesity. 3) Undertake some brisk, physical activity every day. 4) Increase your daily intake and variety of vegetables and fruits: eat at least five servings daily. Limit your intake of foods containing fats from animal sources. 5) If you drink alcohol, whether beer, wine or spirits, moderate your consumption to two drinks per day if you are a man or one drink per day if you are a woman. 6) Care must be taken to avoid excessive sun exposure. It is specifically important to protect children and adolescents. For individuals who have a tendency to burn in the sun, active protective measures must be taken throughout life. 7) Apply strictly regulations aimed at preventing any exposure to known cancercausing substances. Follow all health and safety instructions on substances which may cause cancer. Follow advice of national radiation protection offices. http://www.cancercode.eu /
  • European Code Against Cancer There are Public Health programmes which could prevent cancers developing or increase the probability that a cancer may be cured: 1)Women from 25 years of age should participate in cervical screening. This should be within programmes with quality control procedures in compliance with “European Guidelines for Quality Assurance in Cervical Screening”. 2)Women from 50 years of age should participate in breast screening. This should be within programmes with quality control procedures in compliance with “European Guidelines for Quality Assurance in Mammography Screening”. 3)Men and women from 50 years of age should participate in colorectal screening. This should be within programmes with built-in quality assurance procedures. 4)Participate in vaccination programmes against hepatitis B virus infection. http://www.cancercode.eu/
