Some blood groups are more vulnerable to cancer, the study says

There is a connection between a person’s blood type and the possibility of developing cancer, shows a recent study from Swedish researchers.

Researchers from the Karolinska Institute of Sweden have evaluated and analyzed the data for more than one million people over a period of 35 years, according to a report.

The results indicate that people with O-blood group, which is also known as type 0 (zero) blood, are more protected against cancer.

The study revealed that those with a blood group have a higher risk of developing stomach cancer, while those with blood groups B and AB are more likely to have pancreatic cancer.

Researchers also stated that the formation of cancerous tumors is often caused by alcohol, cigarettes and non-steroidal anti-inflammatory drugs.
