As a medical expert with a focus on endocrinology, I often get asked about the relationship between growth hormones and the risk of cancer. Growth hormones, or somatotropin, are naturally produced in the body and play a crucial role in growth and development. They are also used medically in various conditions, including growth hormone deficiency and certain types of dwarfism. However, there is a concern among some people about the potential link between growth hormones and cancer.
Epidemiological studies have been conducted to examine the potential link between growth hormones and cancer. Specifically, studies involving patients with acromegaly, a condition characterized by an excess of growth hormone, have shown an increased risk of colorectal cancer. Acromegaly serves as a model for examining the effects of elevated growth hormone levels because these patients have higher levels of growth hormone than the general population. The increased risk observed in these patients suggests that there may be a connection between elevated levels of growth hormones and the development of colorectal cancer.
However, it is important to note that the risk of other cancers in relation to growth hormone levels remains unproven. While the studies on acromegaly are intriguing, they do not provide conclusive evidence that growth hormones cause cancer in general. Cancer is a complex disease with multiple risk factors, and it is unlikely that any single factor, including growth hormones, is solely responsible for the development of cancer.
Additionally, a long-term follow-up study of children with growth hormone deficiency who were treated with pituitary-derived growth hormone has indicated an increased risk of colorectal cancer. This study is significant because it looks at the effects of growth hormone therapy in a population that would naturally have a lower risk of developing cancer due to their deficiency. The findings suggest that the treatment itself may not be entirely benign and that there could be long-term effects that need to be monitored.
Despite these findings, it is crucial to consider the context and the overall body of evidence. The use of growth hormone therapy is typically reserved for cases where there is a clear medical need, and the benefits of treatment are believed to outweigh the potential risks. Furthermore, the studies mentioned are observational and cannot establish a direct causal relationship. More research is needed to fully understand the mechanisms by which growth hormones might influence cancer risk and to determine if there are specific subgroups of patients who are at a higher risk.
In conclusion, while there is some evidence suggesting a potential link between growth hormones and an increased risk of colorectal cancer, particularly in conditions of elevated growth hormone levels such as acromegaly, the overall risk of cancer in relation to growth hormone levels is not fully understood. Further research is necessary to clarify these relationships and to guide clinical practice in the safe and effective use of growth hormone therapy.

Epidemiological studies of patients with acromegaly indicate an increased risk of colorectal cancer, although risk of other cancers is unproven, and a long-term follow-up study of children deficient in GH treated with pituitary-derived GH has indicated an increased risk of colorectal cancer.
