Eating right very early on in life is very important but very often, it is not followed through and that can have adverse effects in many ways. A new research by Nature has shown that drastic early-life changes in teens and young adults regarding diet, lifestyle, obesity, environment and the microbiome have led to a "genuine increase" in the incidence of early-onset forms of several cancers globally. 

Over the past several decades, the incidence of early-onset cancers, often defined as cancers diagnosed in adults less than 50 years of age, in the breast, colorectum, endometrium, oesophagus, extrahepatic bile duct, gallbladder, head and neck, kidney, liver, bone marrow, pancreas, prostate, stomach and thyroid has increased in multiple countries.
