Find the secret why cancer cells are resistant to drugs

This secret will bring new hope for patients with cancer in the future.

Cancer is difficult to treat because it is immortal cells , constantly proliferating, forming tumors that invade our entire body.

To develop, these tumors will produce new blood vessels to steal the body's blood supply - which provides oxygen and nutrients to it, then metastasize through the lymphatic system or blood vessels.

Usually a few weeks, cancer cells begin to develop resistance and continue to grow.

Therefore, one of the methods to treat cancer is to use drugs (chemotherapy) to prevent the tumor from creating more blood vessels. When there is no more blood supply, cancer cells will die slowly, and eventually be destroyed.

But that's just theory! In fact, after a period of treatment - usually several weeks - cancer cells begin to develop resistance and continue to grow. That is the reason why cancer patients can often only prolong their lives but cannot treat them completely.

And now, scientists at the London Cancer Research Institute have found why cancer can be resistant to drugs. The reason is because: cancer has the ability to cling, "rob" the available blood vessels of the body to continue to develop.

More specifically, researcher Dr Andrew Reynolds, the researcher, said that tumors, when not supplied with nutrients, automatically move, then surround surrounding blood vessels with cancer cells.

He said: "This is the first study to show in detail the ability of cancer to adapt to current drugs. But also because of that, in the future, we believe that it is possible to develop preventive medicine. This phenomenon occurs " .

Scientists have figured out why cancer can be resistant to drugs.

To achieve this result, Reynolds's team collaborated with the University of Toronto (Canada) to perform experiments on mice with liver cancer. They found that tumors initially tended to stop growing when treated with drugs. But then, the cancer cells began to . loosen the looting, encircle and take advantage of the mice 's available cells.

According to Dr. Reynolds, there are currently a number of drugs that can stop this phenomenon, but still need more tests in the future to ensure the effectiveness and safety of the drug.

At the same time, experts believe that this study is not limited to the treatment of liver cancer, but can also be applied to many other common cancers such as breast, colon, colorectal, kidney and lung.

The study is published in the National Cancer Institute magazine.
