Cancer cases are rising exponentially among millennials and Generation X and the growing threat among youth could be linked to obesity, poor diet, environmental factors, lack of exercise and poor sleep. A study published in medical journal The Lancet reported an increase in diagnosis of 17 types of cancer in young including gastric cardia, small intestinal, Estrogen receptor-positive breast, ovarian, Liver and intrahepatic bile duct in women, colon and rectal, Uterine corpus, Gallbladder and other biliary, Kidney and renal pelvis, Pancreatic, Myeloma, leukemia among others.
The reasons behind rise in cancer among young people are "poorly understood" as per Lancet.
