Obesity can lead to 13 types of cancer, says study
New Delhi: Obesity leads to 13 types of cancer, including that of
pancreas and esophagus, as fat cells affect the processes that regulate the
growth of cancer cells in the human body, says a study.
Due to excess fat in the body, fat cells produce hormones and proteins,
according to the study conducted by the United Kingdom's Imperial College. Besides
being released into the bloodstream, these are also circulated around the body
and this is why they increase the risk of several different types of cancer. Fat
cells are also said to affect processes that regulate cancer cells' growth.
According to the World Health Organisation (WHO), around 1.9 billion
adults worldwide are overweight or obese, and with obesity linked to some 13
types of cancer, the problem of extra weight poses a serious threat to their
lives.
Among the 13 types of cancer, which are believed to have strong
connection with weight gain, are oesophageal (food pipe), pancreatic, liver,
stomach, colon and rectum, gallbladder, lung, kidney and gynaecological cancer.
Among women, breast, ovary or uterus cancer could occur.
"The most common types include breast and colon, while the most
difficult to treat include pancreatic, oesophageal and gallbladder
cancer," said the study. Commenting on the study, Deep Goel, Director of
Bariatric and Gastrointestinal Oncology Surgery at the BLK Super Speciality
Hospital, said that obese had a greater risk of developing and also dying from
several types of cancer.
"Let's say, if there's one normal-weight patient suffering from
pancreatic cancer and another obese patient suffering from the same cancer of
same stage, chances of an obese patient's death are more over normal-weight
patient," said Goyal.
