Human Growth Hormone (HGH) and Colon Cancer The use of Human Growth Hormone (HGH) for “anti-aging” has been increasing, which is concerning because it is not FDA-approved for this purpose. Researchers are warning about a possible link between HGH and colon cancer after reviewing the case of 68 year-old man who died from highly-aggressive colon cancer.

Human Growth Hormone (HGH) and Colon Cancer

One of the first studies to link Human Growth Hormone (HGH) and colon cancer was published in 2002 by The Lancet. After analyzing data on over 1,800 people in the U.K. who used HGH between 1959-1985, they found an overall increased risk of death from cancer, as well as an 8-fold increased incidence of colon cancer.

Case Report of HGH and Colon Cancer

In March 2008, Clinical Gastroenterology and Hepatology published a case report of a 68 year-old man with colonic Crohn’s disease who died from aggressive metastatic colon cancer.

Researchers were concerned about the growing “off-label” use of HGH for “anti-aging” and its potential carcinogenic risk. When doctors performed a colonoscopy, they found a 7-cm growth, and exploratory abdominal surgery found widely metastatic colon cancer. He died of the illness five months later.

Crohn’s disease is a risk-factor for colon cancer, but the man also used HGH treatment for anti-aging purposes for seven years before his diagnosis. It is unknown whether HGH anti-aging treatment may have contributed to the caused colon cancer or accelerated the growth of a pre-existing cancer. However, the man had two colonoscopies in the two years before he was diagnosed, suggesting that the cancer grew very rapidly.

Researchers also detected high levels of insulin growth-factor-1 (IGF-1), which increases in patients who use HGH treatment. Both HGH and IGF-1 are known to stimulate proliferation of cancerous and non-cancerous cells.

What is Colon Cancer?

Colon cancer is a cancer of the large intestine (colon) in the lower part of the digestive tract. When it also involves the rectum (last several inches of the colon), this cancer is known as colorectal cancer. Most case begin as benign (non-cancerous) polyps, which are small clusters of cells that rarely produce symptoms. Over time, polyps can potentially become cancerous. This is why doctors recommend routine colon cancer screenings, especially for people over 65.
