Here’s why: when people sleep, cancer cells migrate and jump into the blood

New Delhi: With the development of medical knowledge, cancer itself is somewhat treatable, but it is still one of the deadliest diseases, particularly when these tumorous cells enter the blood and infect another organ. According to a recent study, when people are sleeping, these tumorous cells from breast cancer patients leap into the circulation.

Cancer spreads when tumorous cells from one area of the body travel through the blood to another. According to the National Cancer Institute, these cells—also known as stage IV cancer—have characteristics more akin to those of primary disease than those of the tissues where metastatic cancer has spread. Doctors can identify cancer that has spread from another place of the body by looking for this.

According to a study in the journal Nature, the dynamics that control the creation and spread of circulating tumour cells are mainly uncharacterized, and it is frequently presumed that they are continuously shed from developing tumours or that they are shed as a result of mechanical trauma.

A difficult human physiology:

A team of Swiss researchers has discovered that circulating tumour cells awaken when the patient is asleep. Circadian rhythms are changes in the body, brain and behaviour that occur on a 24-hour cycle. The majority of living organisms are impacted by these natural phenomena, which predominantly react to light and darkness.

Recovering pattern’s:

Rest-phase cells (CTCs) are prone to metastasising, whereas those generated during the active phase (cts) are devoid of this ability. This contradicts long-held beliefs that cancer cells do not conform to the biological clock and circadian rhythms.

Don’t resist sleeping:

Scientists have discovered that breast cancer cells are more active at night time. Researchers are now looking for better understanding of the unique movement patterns of these cancerous cells.
