At
night, breast cancer grows more quickly
In its advanced stages, breast cancer spreads to other
organs. Researchers have found that while patients are sleeping, circulating
tumour cells become more aggressive.
Breast cancer typically appears as a small, abnormal
lump that becomes larger and eventually spreads to other organs as the disease
worsens. The next topic is metastatic breast cancer. if the tumour grows
further, the duration Women with metastatic breast cancer often live two to
three years after diagnosis.
The primary tumour releases tumour cells that enter
the bloodstream to spread. The circulating tumour cells are these. Since they
can establish themselves anywhere in the body, it is difficult to detect them,
but in the case of breast cancer, they are the bones, liver, lungs, and brain.
The mechanisms that cause metastases to form from the
initial tumour are still mostly unknown. Some experts think they are
continuously produced or as a result of physical or mental harm. Researchers
from Basel and Zurich universities in Switzerland have produced unexpected
results that cast doubt on this axiom.
In fact, their research on mice or breast cancer
patients demonstrates that circulating tumour cells have a "boost" of
activity during sleep. Compared to those created during the day, they are more
likely to develop metastases. Analysis of the RNA expressed by each circulating
tumour cell allowed for this observation.
In conclusion, there is a night-time concentration
rather than a continuous creation of circulating tumour cells with strong
spreading potential.
