Drinking increases risk of cancer

There is a link between drinking of alcohol and risk of digestive cancers.
Pancreatic, liver, gastric, bowel, and gullet cancers are the most common digestive cancers in the world.

Researchers discovered that those who drink more than one alcoholic drink per day are at the risk of digestive cancer.
Gullet cancer risk is increased by just a single drink per day.

Bowel cancer risk is increased by one to four drinks per day. Four or more drinks per day leads to higher risk of gastric, pancreatic, and liver cancers.

Combined drinking with smoking increase the risk of digestive cancers in the upper cavity. Alcoholic content of some beverages may increase cancer risk.

How cancers evade the immune system

Scientists from Singapore has discovered new way cancers escape the body's immune system, looking at gastric cancer GC. In gastric cancer, gene promoters are dysregulated in a way that is different from tumour's antigenic profile to evade the body's immune system.

Epigenetic is a process by which a cell's DNA is chemically changed by the environment, to change gene expression.

Creating comprehensive epigenetic profiles for gastric cancer and normal tissue from the same parent shows that some promoters specifically changed in gastric cancer tissues.

Researchers found out that gene variants can cause cancer growth, the use of less immunogenetic variants can enhance the tumour to bypass the host's  immune system.
