Each of these four groups can then be analyzed more precisely as “positive” or “negative,” so that one can be A positive, B negative, O negative, AB positive, etc. The question is whether the blood contains the so-called Rh protein or not.
Which blood type is associated with a lower risk of cancer?
As mentioned previously, numerous studies have been conducted in recent decades to determine whether certain blood types have a greater influence on the likelihood of receiving a diagnosis for a particular disease.
Yesterday it was reported that people with blood type O are less likely to develop heart disease, probably compared to other blood types that have certain clotting factors related to protein coagulation.

And another piece of bad news: People with blood types A, B and AB have a higher risk of developing stomach cancer.
As previously mentioned, a 2015 study found that blood type O is associated with a lower risk of this diagnosis; however, it is important to note that there is no significant correlation between blood types and cancer mortality rates.
A similar trend was observed in the diagnosis of pancreatic cancer: people with blood types A, B and AB had a higher risk.

Furthermore, it has been shown that blood type O is associated with a lower risk of various types of colon cancer.
Dr. Sanjay Aggarwal, a general practitioner at the Delhi Holistic Health Care Centre, recently stated: “Given the work of scientists on bacterial infections, it might be more accurate to say that people with blood type O have a lower risk of developing pancreatic cancer.”
