Cancer has become one of the leading causes of death worldwide and the number of new cancer cases is likely to rise in the next two decades and touch 22 million, according to National Cancer Institute.

In a recent study, Mark Petticrew, Professor of Public Health at the London School of Hygiene and Tropical Medicine said: "The weight of scientific evidence is clear - drinking alcohol increases the risk of some of the most common forms of cancer, including several common cancers."

The report also states that alcohol industry uses distortion, denial and distraction in order to mislead and cover up the risks of developing cancer from drinking.

Mark Petticrew also mentioned: "Public awareness of this risk is low, and it has been argued that greater public awareness, particularly of the risk of breast cancer, poses a significant threat to the alcohol industry," Daily Mail reported.

Here, we enumerate some factors that can increase the risk of developing cancer:
