Chemotherapy for cancer? Doctor: Not necessarily, chemotherapy is not recommended for these 6 types of patients!

Even if you don't have cancer patients around you, everyone must have learned about cancer treatment methods from various movies, TV dramas and documentaries. The two most popular words among them are "chemotherapy".

　　The reason why everyone is deeply impressed by chemotherapy is that most of the patients receiving chemotherapy look weak and bald. Some medical documentaries also fully describe the side effects of chemotherapy, so everyone who mentions chemotherapy comes from the heart. full of fear.

　　First of all, the so-called chemotherapy is actually an abbreviation for chemical drug therapy, that is, the chemical drugs enter the human body, which can achieve the therapeutic purpose of killing cancer cells.

　　So far, chemotherapy is the most effective treatment for cancer, and its effect is basically on par with surgery and radiotherapy. These three are called the "troika" of cancer treatment.

　　However, unlike surgery, radiotherapy and other treatment methods, chemotherapy has more clinical advantages . Because the first two are actually local treatments, they can only remove or kill local tumors and cancer cells.

　　However, chemotherapy is a systemic treatment , which has direct therapeutic effects on potential metastatic lesions and metastatic cancers . No matter which route the patient chooses to administer, the drug will travel directly along the blood circulation to most of the tissues and organs of the patient's body.

　　Because of this, although chemotherapy has certain side effects, such as bone marrow suppression, hair loss, nausea and vomiting , etc. However, chemotherapy is still the most important treatment method, because the side effects caused by it are only temporary, and new chemotherapy drugs are constantly coming out in the clinic, the side effects of chemotherapy are getting smaller and smaller, and there are drugs that can treat the side effects of chemotherapy.

　　Not only that, but the application of chemotherapy is also more extensive. It can be used in both radical treatment (it is quite sensitive to chemotherapy drugs, and can be cured by chemotherapy, such as leukemia, lymphoma, choriocarcinoma, etc.), or palliative treatment (by killing cancer cells, inhibiting cancer cells, etc.) It can also be used for preoperative and postoperative adjuvant chemotherapy , etc. , which have therapeutic effects on most cancers.

　　However, not everyone is suitable for chemotherapy, such as the following groups of people, chemotherapy is not the best choice:

　　1. The patient's physical condition is extremely poor , for example, after entering the terminal stage , the body can no longer withstand chemotherapy;

　　2. The patient is too old, especially over 75 years old , and may not be able to bear the side effects of chemotherapy;

　　3. The patient itself has severe organ dysfunction, such as renal failure, liver failure , etc.;

　　4. The patient is in the stage of carcinoma in situ and has successfully undergone surgical resection , and usually does not need further chemotherapy;

　　5. Suffering from a special cancer, which is not sensitive to chemotherapy drugs , and cannot achieve the expected results after receiving chemotherapy;

　　6. After multiple chemotherapy treatments , the body develops drug resistance , and the replacement of chemotherapy drugs is still ineffective.

　　Once the above six situations appear, considering from many aspects, the patient can no longer choose chemotherapy, but should start other treatments according to the doctor's recommendation.

　　Finally, it should be emphasized that chemotherapy is originally a double-edged sword. Cancer cells will indeed die and the speed of cancer metastasis will be inhibited, but healthy cells will also be damaged, resulting in various side effects in patients. Therefore, whether it is necessary to choose chemotherapy and how to treat it, patients should follow the doctor's advice and arrangements.
