Cancer, by nature, is a destructive force. Sometimes, it spreads, or metastasizes, to a distant body part. While some cancer cells die during this process, others might go on to create additional tumors.

The majority of treatments are ineffective at curing metastatic cancer, so it is vital to find ways to stop the cancer cells from spreading.

Researchers believe electromagnetic fields can help. While this has been a point of interest for years, it is only recently that experts have begun to unravel the mechanism.
