In a recent study, scientists discovered a link between a certain blood group and the risk of pancreatic cancer.
Cancer occurs when malignant cells acquire the ability to multiply, which leads to the growth of tumors. These tumors continue to invade other tissues if their growth is not tamed, which requires early treatment.
Cancer growth can be caused by several factors, but smoking and excessive alcohol consumption are among the worst culprits.
According to several studies, having a certain type of blood may increase the risk of pancreatic cancer by 72%.
This type of cancer develops when abnormal cells begin to grow inside the pancreas – the organ responsible for producing digestive fluids.
A small number of conditions affect the part of the pancreas that regulates blood sugar.
While there are modifiable risk factors for the disease, there are others that are out of control, including genetic risk factors.
In an early study published in the Journal of the National Cancer Institute, researchers found that people with blood type A, B, or AB were more likely to develop the disease compared to people with type O.
The results indicated that compared to those with blood type O, type A individuals had a 32% higher chance of developing pancreatic cancer.
Those with type AB had a 51% higher chance, and those with type B had a 72% higher chance.
The results measured the risk of developing pancreatic cancer through an analysis of blood samples.
Within the study group, 17% of pancreatic cancer cases were attributed to non-O blood type inheritance.
However, the study authors emphasized that the findings do not establish a direct link between non-O blood groups and the development of pancreatic cancer.
Moreover, other studies using a similar methodology have found different results regarding blood type B and the risk of different types of cancer.
In 2017, research published in the journal PLOS One evaluated the risks of different blood types in relation to colorectal cancer.
“Compared with blood type A, blood type B was associated with a statistically significant decrease in the risk of all types of cancer. Both blood types B and AB were associated with a reduced risk of gastrointestinal and colorectal cancer, respectively,” the researchers wrote.
According to the findings, type B blood was also associated with a lower risk of stomach and bladder cancer.
However, blood type AB has been associated with a significantly increased risk of liver cancer.
The four human blood groups are determined by the sugar and proteins on the surface of red blood cells and other cells in the pancreas.
The pattern in which the sugar molecules form determines whether a person’s blood type is A, B, AB, or O.
Each species can be either positive or negative, and this is usually determined by the genes that an individual inherits from his or her parents.
The rarest blood type is AB negative, while most people have type O.
