What is chemotherapy What is radiotherapy What is the difference between the two

Chemotherapy is the use of drugs** and radiotherapy is the use of radiation**.

Radiotherapy is a physical technique that inhibits and kills tumor cells by irradiating tumor cells. Chemotherapy is a chemotherapy method that uses chemotherapy drugs to kill tumor cells.

The differences between the two are as follows:

1. Radiotherapy is smaller than chemotherapy, and chemotherapy will cause local reactions, mainly allergies, hair loss, bone marrow suppression, nausea and vomiting, sore throat, etc. Chemotherapy not only has local reactions, such as allergies, ulcers, redness and swelling, etc., but also systemic reactions such as: white blood cells, red blood cell decline, anemia, loss of appetite, weight loss, insomnia, bone pain, depression, anxiety, etc.

2. Radiotherapy does not require hospitalization, and a radiotherapy generally only takes 10 or 20 minutes. However, chemotherapy injection takes a long time, and chemotherapy is relatively large, so hospitalization must be required for observation.

3. Radiotherapy is a cancer of local tumors, such as digestion and respiratory system. Chemotherapy has a wide range of applications and can be used throughout the body to inhibit the spread and metastasis of cancer cells.

Medical terminology is one of the three major means of cancer. It is a method of irradiating tumors with various rays of different energies to inhibit and kill cancer cells. Radiotherapy can be used alone or in combination with surgery, chemotherapy, etc., as part of a comprehensive approach to increase the incidence of cancer.

A period of radiotherapy before surgery can be performed to reduce the size of the tumor, so that patients who could not have surgery can have the opportunity to undergo surgery. For advanced cancer, palliative radiotherapy can be used to relieve compression and relieve pain. However, radiation therapy can produce radiation dermatitis, radiation esophagitis, and many other toxic side effects, such as loss of appetite, nausea, vomiting, abdominal pain, diarrhea, or constipation.

chemotherapy

Chemical**), that is, the method of synthesizing drugs with chemical **disease. Chemotherapy is currently one of the main means of tumor and some autoimmune diseases, but in the world, patients generally have obvious nausea and vomiting, which brings discomfort to patients. Chemotherapy refers to the application of drugs ** cancer.

At present, there are more than 50 kinds of chemotherapy drugs, such as epirubicin, doxorubicin, daunorubicin, mitomycin, fluorouracil deoxynucleus, etc. These drugs are often used in combination at different intensities.

Radiation therapy is generally given after surgery, and chemotherapy can be given before or after surgery. In general, patients who cannot be operated on can be treated with chemotherapy.

Radiotherapy (local**) is a radioactive ** tumor, chemotherapy is a chemical drug ** tumor, radiotherapy needs to be localized, and the lesion site should be localized. Chemotherapy is systemic**, and blood concentrations are tended, sometimes many (gastrointestinal reactions are the most common).

Chemotherapy is the infusion of chemotherapy drugs into the body through the vein to kill cancer cells in the body, which is the whole body**, and radiotherapy is to kill local cancer cells through radiation.

Both are systemic and local***.

In the simplest terms, chemotherapy is a chemical drug** that relies on infusions (chemical drugs) to kill cancer cells!

Radiotherapy is radiation, which refers to the use of radiation to eliminate the lesion to **cancer.

Radiotherapy for severe cancers, chemotherapy for mild cases!

Yes, in fact, this radiotherapy and chemotherapy are both important means of tumor, but it is indeed completely different chemotherapy is through drugs, that is, there can be injections, there are also oral chemotherapy drugs, if radiotherapy, radiotherapy is actually radiotherapy, it is a ray that directly kills tumor cells, one is a drug and one is a radiation, this is a different way of medication, originally it is not a drug, that is, the method of medication is different, and the purpose, radiotherapy is for local, for example, like nasopharyngeal carcinoma, Nasopharyngeal carcinoma can rely on radiotherapy, but it is aimed at local radiation to illuminate it, but it is not illuminated in other places in the distance, it will not work with radiotherapy, and then it will depend on chemotherapy, chemotherapy is also effective for you outside the radiation field, so one is that the method is different, and the other is that the purpose is different.
