One meta-analysis summarized it clearly: \u201cBlood group A is associated with increased risk of cancer, and blood group O is associated with decreased risk.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For specific cancers, the pattern appears most consistent with stomach and pancreatic cancers. Studies show that people with blood group A or AB face a higher risk of gastric cancer than those with blood group O. Similarly, pancreatic cancer risk tends to be greater among non-O blood types.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In some populations, other findings vary. For instance, a study of Chinese men found that blood group B had a lower risk of gastrointestinal cancers than group A, highlighting how results can differ by region and genetics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Overall, blood group O appears to offer the lowest relative cancer risk across many cancer types, although the differences are modest. One analysis estimated that people with blood group A had about a 19 percent higher risk of stomach cancer compared to group O.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Importantly, these are associations, not proof of causation. Factors such as diet, smoking, infections like&nbsp;<em>H. pylori<\/em>, and environment strongly influence cancer development and may explain much of the variation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The link also depends on cancer type: for some, like breast cancer, large studies have found no meaningful relationship with ABO blood group.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Having blood group O does not guarantee protection \u2014 it only suggests a slightly lower statistical risk in some studies. Lifestyle choices, screenings, and family genetics remain far more powerful predictors of cancer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short: current evidence points to blood group O as having the lowest average cancer risk, but maintaining healthy habits and regular medical checkups matter far more for prevention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Large scientific reviews and cohort studies suggest that people with blood group O generally have a lower risk of developing certain cancers compared with non-O groups (A, B, AB).
