Men with blood group A are not likely to get prostate cancer than men with other blood groups, despite popular belief. According to some medical writers, your blood group affects your health. In particular, men with blood group A are supposed to be more likely to develop prostate cancer and to get more aggressive forms of the disease. Hence it may be of big concern for men who have type A, but not confirmed as yet.
Researchers at the Institute for Complementary Medicine in California checked the blood group of 200 men who had had a prostatectomy at the State Hospital. They find that men with type A are no more likely to get cancer. And when they looked at the stage of the cancers, they also learned that type A men did not have more aggressive tumours. So men can be reassured on that count. There are more risk factors for prostate cancer which are yet to be confirmed.
