Obesity is now a risk factor when it comes to tumour growth and cancer.
It is also a known fact that obesity increases the risk of inflammation, which has long been associated with cancer.
Obesity is now believed to affect cancer cell metabolism and immune clearance, which is contributive to the growth and spread of tumours.
“Obesity is increasing dramatically worldwide, and is now also recognised as one of the major risk factors for cancer, with 16 different types of cancer linked to obesity ,” said Cornelia Ulrich from the University of Utah in Salt Lake City, US.
“We urgently need to identify the specific mechanisms that link obesity to cancer,” Ulrich said.
In the study, published in the journal Cancer Prevention Research, Ulrich and colleagues conducted a literature review covering publications from January 1946 to March 2017, seeking studies that explored crosstalk between adipose tissues and carcinomas.
They ultimately found 20 primary research publications that specifically addressed the topic, illustrating the novelty of this work.
