What does radiotherapy mean? What is the basis for radiotherapy?

Radiotherapy is radiation**, which refers to the use of radiation to eliminate the lesion. Radiation as malignancy.

An important means for many cancers.

It can produce good results. However, radiotherapy can produce radiation dermatitis, radiation esophagitis, loss of appetite, nausea, vomiting, abdominal pain, diarrhea or constipation and many other toxic side effects, using traditional Chinese medicine and chemotherapy.

Cooperation** can not only effectively eliminate these toxic side effects, but also increase the radiosensitivity of cancer cells, helping radiation to completely kill 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.

Radiotherapy is a kind of localization, radiotherapy, that is, radiation, is a method of irradiating tumors with various different energies to inhibit and kill cancer cells"Bake electric"。

Chemotherapy is a systemic malignancy, and chemotherapy is the application of chemical drugs (including endocrine drugs, etc.) for malignant tumors. Chemotherapy drugs are often introduced into the body intravenously, orally, or in other forms to kill tumors.

Radiation is a method of using radiation such as radioisotopes generated, rays and X-rays, electron rays, proton beams and other particle beams produced by various X-ray machines or accelerators.

There are many differences, 1. The scope of use is different, radiotherapy: local, with limitations, often used for local malignant tumors, such as breast cancer, nasopharyngeal cancer, etc. Chemotherapy.

Chemotherapy is suitable for any tumor in the body, including metastasis of cancer cells throughout the body. 2. Different radiotherapy: It is relatively small, mainly local reactions, basically no systemic reactions, mainly redness, allergies or sore throat.

Chemotherapy: systemic and local reactions, common local reactions are redness, swelling, ulcers and allergies, systemic reactions are more serious, common are bone marrow suppression, anemia and nausea and vomiting, accompanied by hair loss. 3. **The time is different, radiotherapy:

Generally, a radiotherapy treatment only takes about ten minutes, and the time is short and does not require hospitalization. Chemotherapy: Generally, intravenous chemotherapy drugs are injected, the time is relatively long, and the chemotherapy drugs are relatively large, so patients must be hospitalized for observation during chemotherapy.

The patients undergoing radiotherapy were indeed in pain, with red bars painted on their faces, unable to eat or drink, and their blood levels were extremely low.

There is no difference in nature between radiotherapy and chemotherapy, both are a type of cancer. People who do radiation therapy will also be more painful, the process will be more painful, and the hair will fall out.

Radiotherapy mainly uses radiation to kill tumors, and chemotherapy uses chemical drugs such as oral chemotherapy drugs and systemic intravenous chemotherapy drugs to ** tumors. Radiotherapy is mostly painless, but many times it will leave sequelae, such as different degrees of organ damage.

Radiotherapy, referred to as radiotherapy, refers to a method of emitting some radiation to malignant tumors through radiation, such as isotopes, such as alpha, beta, gamma rays, and X-ray machines. Radiotherapy is a local method, which was first used for laryngeal cancer, and has achieved obvious results. At present, radiotherapy, as one of the three conventional means of malignant tumors, plays a pivotal role in clinical practice.

According to WHO statistics, the contribution rate of radiotherapy in malignant tumors has reached 41%.

Analysis: As the incidence of tumors increases, more and more people have heard of radiotherapy, or people around them who are undergoing radiotherapy. But most people don't know much about radiotherapy, what exactly is radiotherapy?

Marie Curie is no stranger to everyone, it is because of the famous Nobel Prize winner in physics discovered the radioactive element "radium", thus starting the precedent of radiotherapy, after countless physicists, medical scientists for more than 100 years of continuous exploration and research, radiation has been able to develop by leaps and bounds, forming a set of oncology, radiation physics, radiation biology, radiation biology in one of the three major methods of modern tumors. 70% of tumors require radiotherapy, and there are many tumors that are the preferred method of radiotherapy, such as nasopharyngeal cancer, early laryngeal cancer, head and neck lymphoma, basal cell carcinoma, etc., and the effect is significant.

Radiation is the use of radiation to kill tumor cells, so as to achieve the purpose of **tumor. Modern radiology has a high level of science and technology, which is far from being as simple as "drawing a line" as people imagine, and it is not "physiotherapy" as some people think. After the tumor is diagnosed, if radiotherapy is required, it is first necessary to prepare for radiotherapy, including CT, MRI examination, liver and kidney function, blood routine, B ultrasound, chest X-ray and other examinations, the doctor will determine the scope of radiotherapy according to the imaging examination, clinical examination and pathological examination, select the type and dose of radiation, and use the radiotherapy plan system to formulate a radiotherapy plan, such as the angle and direction of radiation delivery, to ensure that the irradiation target area can be included within the 90% equal dose line, and at the same time try to make important tissues and organs not or less damaged by radiation.

Then the technician will carry out the projection, and in the process, according to the tumor retreat, the program will be continuously improved. The designation and implementation of the radiology plan often involves the knowledge of oncology, imaging, physics and biology, and the equipment required is also high-precision instruments, such as simulators, computer radiology planning systems, network systems, linear accelerators, CO60 machines, X-ray machines, etc. Any tissue and organ has a specific tolerance to radiation, and the radiation dose exceeds its tolerance amount, which will cause a series of radiation complications, and the late radiation damage can occur decades later, seriously affecting the quality of life of patients, so the determination of radiation dose must be carried out under the guidance of a radiologist.
