Cancer is a systemic disease. Even if tumors that grow in a certain part of the body, such as lung cancer, liver cancer and breast cancer, are removed, the factors that can promote the formation of cancer may still remain in the body after surgery, which is why many cancers will still recur and metastasize after successful surgery.

Confirmation: Chemotherapy Accelerates Cancer Death has gone viral on the Internet and major social media. Chemotherapy, along with surgery and radiotherapy, has always been called the carriage of tumor treatment. However, in this article, the author moved out of the "Reuters Report" and "expounded" the immune theory of natural killer cells (NK cells) from the perspective of molecular biology, and "advised" tumor patients to refuse chemotherapy, but to supplement some health care products that can provide immunity.

What role does chemotherapy play in cancer treatment?

Chemotherapy is a treatment method that uses drugs to kill cancer cells, and it works by preventing or slowing down the growth of rapidly dividing cancer cells. Chemotherapy is usually "killing one thousand enemies and losing x hundred", because drugs will also attack healthy cells that divide rapidly in the human body, so there will be side effects such as hair loss. Usually, the side effects will disappear after chemotherapy.

From surgery, chemotherapy, radiotherapy, to targeted therapy with less side effects, to immunotherapy with more lasting effects, new treatments for cancer emerge one after another, but chemotherapy is still the cornerstone of cancer treatment, which is needed by many cancers, especially some tumors that are sensitive to chemotherapy, such as small cell lung cancer and leukemia.
