Breast cancer

Caucasians with blood type A may have a higher risk of breast cancer than other Caucasians. No association was found in any other blood type or any other population. Similarly, the Rh factor had no association with the risk of breast cancer.

Caucasians with blood type A may have a higher risk of breast cancer than other Caucasians. No association was found in any other blood type or any other population. Similarly, the Rh factor had no association with the risk of breast cancer.
Influence of ABO blood group and Rhesus factor on breast cancer risk: a meta-analysis of 9665 breast cancer patients and 244,768 controls.
Blood group “A” and “Rhesus +ve” have high risk of breast cancer, while blood type “AB” and “Rhesus -ve” are at low peril of breast cancer. Physicians should carefully monitor the females with blood group “A” and “Rh +ve” as these females are more prone to develop breast cancer. To reduce breast cancer incidence and its burden, preventive and screening programs for breast cancer especially in young women are highly recommended.

Leukemia

Lung cancer

Ovarian cancer

A study at Harvard University found that women with AB or B group blood have a raised risk of developing ovarian cancer.

Pancreatic cancer

Median age was 62 (34-82) years. Gender: female 73/44%; male: 93/56%. Observed blood group proportions: 0: 43 (25.9%)/A: 94 (56.6%)/B: 16 (9.6%)/AB: 13 (7.8%)/Rhesus positive: 131 (78.9%)/negative: 35 (21.1%). We detected a significant difference to the German reference distribution of the AB0 system (Chi(2) 19.34, df 3, p < 0.001). Rhesus factor has no impact on AB0-distribution (Chi(2) 4.13, df 3, p = 0.25), but differs significantly from reference distribution-probably due to initial AB0-variation (Chi(2) 4.82, df 1, p = 0.028). The odds ratio for blood group A is 2.01 and for blood group 0 is 0.5.
The incidence of PC in the German cohort is highly associated with the AB0-system as well. More patients with blood group A suffer from PC (p < 0.001) whereas blood group 0 was less frequent in patients with PC (p < 0.001). Thus, our findings support the results from other non-German surveys. The causal trigger points of this carcinogenesis correlation are still not known.
