**9. Conclusions**

Boron is a vital element for living organisms. Boron and several types of its compounds have different beneficial effects in humans at sufficient doses. However, too little or too much intake in the required amount causes serious health problems. Its use as a food supplement to prevent boron deficiency in the body has become popular today. In addition, the use of boron and its compounds in many fields such as cosmetics, cleaning, medicine, electronics, war industry, and the development of new products for these fields are increasing day by day. Such reasons cause an increase in exposure not only to individuals working in boron mines, but also in daily life. Besides, boron and its compounds appear as candidate molecules in the treatment of various diseases. All of these factors indicate that there will be more exposure to boron and its compounds today and in the future. For this reason, it is a fact that these compounds, which are mentioned as having many benefits under normal conditions, will also encounter toxic effects due to the increased exposure over time.

It is also possible that some boron-containing compounds can be candidates for cancer treatment through their structural effects and cytotoxic effects on cellular mechanisms. This shows the importance of toxicity studies of these compounds at all times. However, developing scientific technologies will also enable these effects to be minimized.
