Excess doses of calcium may be a solution to malignant tumors. Scientists have created an anti-tumor drug that stimulates the influx of calcium, which destroys cancer cells.

Calcium ions play a critical role in cellular function, but can become harmful when exposed to high doses. After successful experiments on cancer cells in a group of mice, the researchers concluded that exposure to near-infrared radiation stimulates the action of the drug, leading to the disappearance of the tumor. The researchers focused on two main channels: One is located in the outer membrane, and the other is in the endoplasmic reticulum, which is a cellular organelle that stores calcium ions.
