Scientists find that the spread of breast cancer accelerates during sleep

The scientific community believed that breast tumors continually release metastatic cells, but a scientific team Swiss found that cancer cells that circulate and later metastasize mainly occur during the sleep phase.

This is the main conclusion of a study involving 30 patients and mouse models published in the journal Nature, conducted by researchers from Federal Polytechnic School (ETH) of zürichoh Basel University Hospital it’s up to University of Basel.

Breast cancer is one of the most common forms of cancer, according to World Health Organization (SGD). Each year, approximately 2.3 million people contract the disease worldwide.

If doctors find the cancer in time, patients usually respond well to treatment. However, things become much more difficult if the cancer has already metastasized, recalls the ETH.

Metastasis occurs when circulating cancer cells break away from the original tumor, travel through the body through blood vessels, and form new tumors in other organs.

According to those responsible for the work, until now, cancer research has not paid much attention to this question of when tumors release metastatic cells.
