…insulin signaling can be seen as enabling tumor development by providing a mechanism for PI3K activation and enhanced glucose uptake. This idea is supported by studies showing enhanced tumor development in humans and mice with hyperinsulinemia, and reduced tumor development in states of reduced insulin levels.
There is a new field of cancer research that is only just now starting to take shape but is promising to greatly increase our understanding of cancer and what can influence how it develops over time. This field is being called metabo-oncology.

April 1, 8:00 AM to 12:00 PM 1226 / 4 – A novel polymer-conjugated methionine aminopeptidase 2 (MetAP2) inhibitor SDX-7320 inhibits the growth of EO771 mammary gland tumors and ameliorates the immunosuppressive tumor immune micro-environment (TIME)
Rates of six different cancers that are associated with obesity increased among adults ages 25-49 between 1995 and 2014, according to the research, which was published in the journal Lancet Public Health and based on information in the Cancer in North America database. These cancers include multiple myeloma, colorectal, endometrial, gallbladder, kidney and pancreatic.
Dr. Lewis Cantley discusses targeting the PI3K pathway in breast cancer and the importance of managing ambient insulin levels during therapy.
Cancer patients who are obese face a greater risk of dying from cancer compared to non-obese patients (Calle, 2003). Excess visceral adiposity is believed to contribute to metastasis and progression of cancer via multiple mechanisms: increased secretion of the adipose tissue hormone leptin, decreased secretion of adiponectin, increased production of estrogen in adipose tissue, and elevated insulin (secondary to peripheral insulin resistance) as well as the local effects of inflammatory cytokines (Gucalp, 2016).
Women with breast cancer and diabetes have a greater risk for all-cause and cancer-specific mortality and are less likely to receive chemotherapy and radiotherapy compared with women with breast cancer alone, according to researchers.
About 40 percent of all cancers in the United States -- more than 630,000 in all -- are associated with excess weight, health officials said Tuesday, urging a renewed focus on prevention. The rates of these overweight- and obesity-related cancers are rising, in contrast to the overall rate of new cancer cases which has dropped since the 1990s.
"When assessing cancer risk, body mass index (BMI) and fat percentage may not be adequate measures as they fail to assess the distribution of fat mass," she explained. "Avoiding central obesity may confer the best protection."
