Is there any scientific evidence that taller people are more likely to get cancer?


Through the ages, the description of tall is almost commenatory words, “tall and powerful”, “Yushu linfeng”, “burly”……Whether male or female, to be tall is one of the pursuits of life.Lack of height is a constant pain for many short people.But is being tall always an advantage?Some people say that tall people are more likely to get cancer. Is there any scientific evidence?In fact, the association between height and cancer risk has been reported in the literature since the 1980s.The conclusion was almost unanimous that the higher the height, the greater the risk of cancer.In 2011, the prestigious Journal The Lancet Oncology published the results of Britain’s prestigious Million Women Study.By following more than a million women in the UK for an average of 10 years, scientists found a linear relationship between height and cancer risk, with the average British woman’s risk of developing cancer increasing by 16 per cent for every 10cm increase in height.The study compared 17 common cancers in women and found that 15 of the most common cancers increased in risk, with the highest increases being kidney cancer (up 29 percent), leukemia (up 26 percent), colorectal cancer (up 25 percent) and breast cancer (up 17 percent).A 2020 study published in the Annals of Oncology, a journal of the European Society of Oncology and the Japanese Society of Oncology, found that based on 34 years of follow-up data from two large coeds of more than 170,000 people, men had a 39 percent higher risk of developing cancer than women, and that a staggering 30 percent (35 percent) of the increased risk could be explained by height.Height was also more strongly associated with several major cancers at higher risk for men.Among men, the risk of melanoma and gastrointestinal tumors increased with height.Among women, the risk of melanoma, non-Hodgkin’s lymphoma, gastrointestinal cancers, pancreatic, lung, brain and blood cancers was proportional to height.Each 10cm increase in height was associated with an 8% increase in cancer risk in men and a 10% increase in cancer risk in women.On March 1, 2022, researchers at Johns Hopkins University published a similar study in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Researchers analyzed data from 47 observational studies involving 280,660 cases of colorectal cancer and 14,139 cases of colorectal adenoma.The study concluded that taller people may be more likely than shorter people to develop colorectal cancer or colon polyps, which can later become malignant.The tallest men had a 24 percent higher risk of colorectal cancer than the lowest;Each 10cm increase in height increased the risk of colorectal cancer by 14 percent and the risk of adenoma by 6 percent.So height should be considered a risk factor for colorectal cancer screening, the researchers said.Why Are Tall People more likely to get Cancer?The prevailing “growth hormone” theory holds that tall people are often at greater risk of cancer because their bodies produce more growth hormone, which stimulates cell division and growth.Another theory is that taller people have larger organs.So there are more cells in the whole group, which causes some of them to have a higher chance of mutating.It has also been suggested that taller people are more active in cell proliferation and are more likely to have mutations.In short, the exact mechanism by which height increases cancer risk is unclear.Despite the findings, tall people should not be alarmed. The causes of cancer are so complex that it is possible to offset or mitigate the risk of being tall by living with minimal exposure to cancer risk factors.
