In this open access article lost opportunities for cancer prevention are discussed including tobacco, asbestos, DDT, dioxins, such pesticides such as phenoxy acetic acids and glyphosate.
Mostly there has been a long time period between the first publications on cancer risks until preventive measurements have been undertaken. Thereby the possibility to save lives has been lost.
One more recent example is exposure to radiofrequency (RF) radiation that in 2011 was evaluated by IARC at WHO to be a possible human carcinogen, Group 2B. Since then the evidence has increased so that RF radiation could be classified as a human cancer-causing agent. Based on published case-control studies the numbers of persons with brain and head tumours that could have been prevented are calculated. The study reports also increasing rates of brain tumours in Sweden based on the hospital in-patient register both in men and women.
