血型和腫瘤的關係： 看看維基百科怎麽說
http://en.wikipedia.org/wiki/ABO_blood_group_system
Disease risks
Compared to O group individuals, non-O group (A, AB, and B) individuals have a 14% reduced risk of squamous cell carcinoma and 4% reduced risk of basal cell carcinoma.[47] Conversely, type O blood is associated with a reduced risk of pancreatic cancer.[48][49] The B antigen links with increased risk of ovarian cancer.[50] Gastric cancer has reported to be more common in blood group A and least in group O.[51]
According to Glass, Holmgren, et al., those in the O blood group have an increased risk of infection with cholera, and those O-group individuals who are infected have more severe infections. The mechanisms behind this association with cholera are currently unclear in the literature.[52]
Pseudoscience
During the 1930s, connecting blood groups to personality types became popular in Japan and other areas of the world.[53] On the contrary, there are some positive science studies.[54][55]
Other popular but unsupported ideas include the use of a blood type diet, claims that group A causes severe hangovers, group O is associated with perfect teeth, and those with blood group A2 have the highest IQs. Scientific evidence in support of these concepts is nonexistent.[56]
