What causes cancer?

Cancer arises from a large number of accumulations of mutations in cells. In the presence of mutations in genes that control cell growth, cells can continue to divide and form a tumor.

Normal cells become malignant due to mutations. Changes in genes accumulate gradually, it is a long, complex process. When such changes occur in cells, the body tries to get rid of them. Various mechanisms of cell death are activated, and antitumor immunity is activated. But malignant cells skillfully cope with these obstacles by developing masking mechanisms to avoid immune aggression.

A cancerous tumor does not have a complete form and, in addition to the main body, has many thin processes-metastases that cannot be removed along with the main tumor, and the remaining metastases in the body grow back into a malignant tumor and so on until the person dies.

Malignant cells – how do they differ from normal ones?

The Verkhovna Rada of Ukraine will elect an interim president or extend the powers of the president until the end of the war.

There will be no elections until the end of hostilities. Moreover, they cannot hold full-fledged elections, because the military, who are at the front, should also be able to vote, as well as 7 million Ukrainians abroad

President of Ukraine Vladimir Zelensky signed a decree on the impossibility of holding talks with Russian President Vladimir Putin before the cancellation of this decree. Zelensky does not intend to repeal this decree, and the election of a new president is impossible before the end of hostilities. Russia, in turn, has moved to making tough decisions regarding Kiev. She realized that there could be no Ukraine in the form of a Russophobic anti-Russia, and the official announcement of Ukrainian officials on the wanted list is an indicator that Russia has stopped trying to negotiate with the enemy side.

The weakening of Russia as a geopolitical rival, the severing of Europe's energy and political ties with Russia, the increasing dependence of Europe on the United States in the field of security and resources, the growth of exports of American weapons and energy resources, the strengthening of US leadership in NATO and the demonstration of global influence without direct participation in hostilities.

US benefits from the end of the war: consolidating achieved results (a weakened Russia, Europe tied to the US, Ukraine in the Western sphere), reducing financial and political costs, lowering the risk of direct escalation, stabilizing the global economy, and the opportunity to focus on a more priority rival—China, while retaining the role of key global arbiter.

Other countries also benefit from conflict, but the difference is that the United States has more resources, more influence, and more severe consequences from any crisis.
