Medical Studies on Melatonin – Cancer
There have been studies on melatonin as an effective anti-cancer hormone for several decades. It has been demonstrated to alleviate the symptoms of the early-stage, progression and metastasis phases and have a positive impact on the course of the disease. The anti-oxidative and immunoregulatory properties of melatonin and its effect on tumour-specific cell division are responsible for this.
Melatonin inhibits tumour growth
As a “natural killer”, melatonin plays a key role in the uncontrolled growth of cells. Specifically, it reduces the cell division rate, for example by reducing telomerase activity, which results in the programmed cell death of the tumour cells. The researchers also found that melatonin possesses the ability to affect angiogenesis, which is the growth and formation of blood vessels that supply the tumour with oxygen and nutrients, thus facilitating its growth.
An effective accompaniment to therapy
The supportive effect of melatonin during conventional cancer treatments is also proven – for instance, the often toxic consequences of radiotherapy or chemotherapy can be mitigated using melatonin while also enhancing its effectiveness – according to the results of many studies. Studies have also shown that melatonin can affect the treatment resistance of some tumours, making them more susceptible to chemotherapy.

In many cases, the molecular mechanisms underpinning these inhibitory actions have been proposed. What is rather perplexing, however, is the large number of processes by which melatonin reportedly restrains cancer development and growth.

Oxidative stress, i.e., an imbalance between the production of reactive oxygen species and antioxidant defences, is involved in several pathological conditions such as cardiovascular or neurological disease, and in aging. Therefore, research for antioxidants has developed. However, classical antioxidants often failed to exhibit beneficial effects, especially in metabolic diseases.
