German researchers have stated that cancer patients rarely die in the country because of the initial tumor, but more because of tumors caused by the tumor. So what?
Cancer cells are called metastatic cancer, a malignant tumor that occurs when cancer cells separate from the original region (the first cancerous area), then pbad through the blood or lymphatic system to another location, and a new cancerous tumor elsewhere in the body, according to the National Cancer Institute of the United States.
This cancer is also called cancer, metastasis and secondary cancer. The attached videos explain how metastatic cancer spreads from different areas of the body, such as cancer of the intestine or ovarian cancer.
It is necessary to make rapid progress in this regard, as 90% of the 230 000 cancer deaths in Germany are caused each year by cancerous foci of the original tumor, said Andreas Fischer of the German Center for Cancer Research in Heidelberg.
Fischer made the remarks on the occasion of World Cancer Day Monday, celebrated on February 4th of each year.
"The risk of dying from cancer transmission to other parts of the body after surgical removal is high in most types of malignancies," said the expert.
He pointed out that tumor-transmitted cancer cells, which had not been discovered, wandered around the body before the tumor was removed, "which makes the tumors treacherous".
Today, it is often easy to surgically or chemically remove the original malignancy, but transitions develop from a few very small, very strong cells, Fisher explained.
"Even though the cells produced and dispersed from the initial tumor die at 99.9%, few of them sleep deep in a limb, but we do not know what to wake up later", a- he declared.
The detection of these "dormant cells" and their prevention of survival and growth pose a major challenge for scientists and scientists, according to the German expert.
