Found a new feature of breast cancer

This type of cancer, as the study shows, spreads more efficiently at certain times of the day.

According to the World Health Organization (WHO), breast cancer is one of the most common types of cancer in the world. Every year, 2.3 million cases are recorded on the planet. A new study by Swiss scientists shows that metastases during breast cancer spread most strongly at night, when sick women sleep, reports express.

It is now known that if breast cancer is detected at an early stage of development, even before metastases have spread, this disease can generally be cured. The spread of metastasis is the spread of cancer cells from the original tumor throughout the body. Due to this, tumors can appear in other organs.

The spread of metastasis

Previously, scientists believed that metastases spread constantly, and therefore did not pay much attention to this process. But a new study shows that metastases spread most effectively when women with breast cancer are sleeping, which is at night.

As part of the study, scientists from ETH Zurich studied the spread of metastases in women with breast cancer.

“We found that a cancerous tumor produces more cancer cells at night, when the body sleeps. These “night” cells can divide faster, which leads to a more accelerated process of spreading metastases throughout the body, compared to “daytime” cancer cells” , says Nicola Aceto from ETH Zurich.

The level of cancer cells in the blood of patients differs depending on the time of day

According to scientists, the release of cancer cells from the tumor is controlled by a hormone such as melatonin, which determines the daily rhythm for the body, that is, the change of day and night. The researchers also found that the time to collect blood samples and tumors from patients can affect the results. The study showed that the level of cancer cells in the blood of patients differs depending on whether the blood was taken for analysis – during the day or at night.

“These results suggest that the timing of sampling during patient care should be recorded so that the exact spread of the disease can be seen,” says Aceto.

The next stage of research

Now scientists have focused their attention on how the new data can be used to improve current treatments not only for breast cancer, but also for other types of this disease.

“Now our task is to find out whether cancer cells behave during the disease of other types of cancer in the same way as cells do during the development of breast cancer,” says Aceto.

The scientists also want to find out whether cancer treatment will be more effective if patients are treated at different times of the day.

Focus already wrote about how the experimental cancer treatment drugwhich caused remission of the disease in 100% of the tested patients.

Also Focus wrote that dangerous disease from the past becomes resistant to antibiotics. We are talking about such an intestinal disease as typhoid fever, which in 20% of cases, if left untreated, leads to death.
