Cancer Patients Lack History of Common Childhood Illnesses
Lack of history of fever, cold, common childhood illnesses observed in cancer patients,
Clinical oncologists repeatedly report that cancer patients stress in their history that they were never ill before the onset of cancer. As a result of this observation, a number of epidemiological studies have been conducted. In 1894, Laurence  acknowledged the fact that cancer patients have a ‘... remarkable disease-free history ...’. In 1910, Schmidt  confirmed these findings in observing ‘afebrile (missing fever) diathesis (constitution)’ in the case histories of 241 cancer patients. Later, in 1934 and 1935, Engel [44, 45] observed a similar finding when comparing 300 cancer patients with 300 patients not suffering from cancer. Individuals who had never experienced a febrile infectious disease were 2.5–46.2 times more likely to have developed cancer than those who had had febrile infections. In 1936, Sinek  reported similar results for 232 cancer patients and 2,444 controls.
In a study of 300 women with ovarian cancer, Newhouse et al.  correlated sociological factors and found fewer marriages and lower incidences of mumps, measles or rubella in the cancer group compared to an age-matched control group. Remy et al.  found an increased risk for cancer among patients who had no [odds ratio (OR) = 2.6] history of former infectious organ diseases, no history of common colds (OR = 5.7) and no history of fever (OR = 15.1).
