What are the side effects of chemotherapy drugs?
1, chemotherapy drugs not only kill cancer cells, but also kill healthy cells in the human body, which reduces the human immunity and can't resist the invasion of bacteria and viruses. The weather will be a little cold, and the body will feel uncomfortable and have a cold and fever.
2. Patients who have received chemotherapy drugs have poor physique, weak walking, fragile bones, massive loss of calcium, osteoporosis and bone and joint diseases.
3. Chemotherapeutic drugs will enter the respiratory system and blood circulation system of human body through blood and respiratory tract, which will reduce the hematopoietic function of the body, inhibit breathing, and damage the health of organs such as liver, heart, kidney, bladder, heart and blood vessels.
4. Long-term exposure to chemotherapy drugs will also damage the oral mucosa of the human body, causing problems such as swelling and pain of gums, inflammation of lips and oral ulcers.
5, chemotherapy drugs can cause severe allergic reactions in the body, a lot of hair loss, and the body has unknown reasons.
6. Patients receiving chemotherapy drugs will have symptoms such as loss of appetite, nausea and vomiting, and weight loss due to the invasion of chemotherapy drugs.

What is chemotherapy?
Chemotherapy is an examination of chemical drug treatment, and cancer cells can be killed by using chemotherapy drugs. Chemotherapy is one of the most effective methods to treat cancer at present, and it is also called the three major treatment methods of cancer together with surgery and radiotherapy.
Surgery and radiotherapy are both local treatments, which are only effective for a certain part of the tumor, but have no obvious therapeutic effect on potential metastatic lesions and actual bone metastasis and cell metastasis, so it is difficult to exert real curative effect.
Chemotherapy is a means of systemic treatment. No matter how it is administered, chemotherapy drugs will spread to the whole body and all organs and tissues with blood circulation. Chemotherapy is the most important treatment for some tumors that have spread to the whole body and have metastasized to the middle and late stages.
What are the contraindications of chemotherapy?
1. A few patients themselves are not sensitive to chemotherapy drugs, and it is difficult for drugs to achieve the expected curative effect. Other treatments are needed to help patients eliminate cancer cells.
2. Patients with early cancer or surgically removed tumors do not need chemotherapy.
3. People with severe organ dysfunction are not suitable for chemotherapy.
4. Patients with drug resistance after repeated chemotherapy need to change other treatment methods in time.
5. Patients who are in poor health or too old, and those who can't afford chemotherapy drugs, are not suitable for chemotherapy.

Do you know how desperate cancer patients with chemotherapy are? Chemotherapy took away "half life"!
Chemotherapy can be said to be a double-edged sword. On the one hand, chemotherapy can help patients kill cancer cells in the body and prolong life. On the other hand, chemotherapy will increase the burden and pressure of patients and make them miserable.
Many patients who have undergone chemotherapy compare chemotherapy to "a sharp weapon to take away their half-life". How many cancer patients lost their lives because they couldn't stand the attack of chemotherapy drugs?
Since chemotherapy drugs are so toxic, why is chemotherapy the primary treatment?
1 World War II, people began to use deadly chemical weapons. Mustard gas is regarded as the "king of poison". People exposed to this toxin will have skin ulcers, central nervous system disorders, cardiovascular complications, organ failure, and eventually die.
Using this toxin to harm people is no different, so it is a terrible torture. When researchers studied mustard gas, they extracted a substance from a soldier's body for medical treatment. Medical experts have found that substances in meson gas can effectively kill cancer cells. With the continuous development of medical technology, the substances in mustard gas have gradually evolved into today's chemotherapy drugs.
1942, Yale New Haven Hospital, USA, a patient with advanced lymphoma, received five times of chemotherapy, and his cancer cells magically disappeared. Once the news was released, it was unanimously recognized by many medical practitioners and people from all over the world, and chemotherapy drugs were officially circulated.
However, just a few weeks later, the patient's cancer cells appeared again, and there were obvious side effects due to the invasion of chemotherapy drugs.
Time has come to 1950, and chemotherapy drugs have once again ushered in a turning point. After years of clinical experiments, chemotherapy drugs that can completely cure Hodgkin's lymphoma have been successfully developed by continuously reducing or increasing drugs and combining drugs. On this basis, chemotherapy drugs with different functions appeared.
Although the current medical level is very advanced, there is still no drug that can completely cure cancer, a terrible malignant tumor disease. The diagnosed patients can only inhibit the growth of cancer cells and delay their life expectancy through chemotherapy.
According to different cancer treatment methods, the chemotherapy drugs used will be different.
Different from ordinary cells, cancer cells have the characteristics of infinite proliferation and differentiation, which can quickly spread to bones, liver, kidney, bladder, heart and other organs in just a few days until the whole system functions fully. If we can't kill cancer cells in a short time, cancer cells will spread all over the body, and then human life will slowly fall down.
Although chemotherapy and drugs have great side effects on human body, modern people still can't get rid of the control of chemotherapy drugs, and patients diagnosed with cancer also need chemotherapy to restore their health.
