What is the difference between chemotherapy and radiotherapy in cancer treatment? What is the differ

It is not possible to generalize.

What is Chemotherapy?

Chemotherapy is a way to use chemical drugs to kill tumor cells, inhibit the growth and reproduction of tumor cells and promote the differentiation of tumor cells.

The disadvantage is that the selectivity of chemotherapy drugs is poor, and at the same time as achieving the best effect, there are often different degrees of toxicity; During the process of chemotherapy, the body is weakened, listless, sweating, white blood cells and platelets decrease, and even red blood cells and hemoglobin decline one after another, and even force the patient to stop**, the use of traditional Chinese medicine and chemotherapy can effectively eliminate these toxic side effects, and at the same time form a synergistic effect with chemotherapy to increase the effect of chemotherapy.

What is radiotherapy?

Radiotherapy is one of the three major methods of cancer. It is a shot with a variety of different energies.

A method of irradiating tumors with rays to inhibit and kill cancer cells. Radiation therapy can be done alone.

It can also be used alone in combination with surgery, chemotherapy, etc., as part of the comprehensive ** to:

Increase the rate of cancer. A period of radiation therapy is given before surgery to reduce the size of the tumor.

This will allow patients who were previously inoperable to win the opportunity to undergo surgery. For advanced cancer, palliative radiotherapy can be used to relieve compression and relieve pain.

Radiotherapy can be divided into two types: ** radiotherapy and palliative radiotherapy. The former is more dosage.

Large, more thorough irradiation, suitable for early and some advanced patients, to eliminate the primary.

foci, possible residual lesions after surgery, and some metastases. The latter is suitable for advanced patients.

It is mostly an expedient measure. Doses are given according to tolerance to improve symptoms and reduce.

Reduces pain and prolongs life. Individual can also achieve the effect of **.

The doctor determines the total dose based on the nature, location, stage of the disease, and general condition of the tumor.

Measure. The total dose is allocated to 20 30 doses, which are irradiated in 4-6 weeks. Accurately.

Positioning, drawing marks on the surface of the body, through the surface of the body, irradiating to the tumor site. Hence the body surface.

Do not scrub off the frames and other positioning marks you have drawn.

You can't tell. Estimated possibility: 1, mediastinal lung cancer (don't be afraid, depending on the pathology, I hope she isn't!) ）。2. Mediastinal lymphoma. 3. Malignant thymoma.

If the boundaries are clear and the extent is clear, surgery is preferred**. According to the pathological situation after surgery, it can be combined with radiation, with the aim of expanding the scope of surgery and ensuring the effect of surgery. Then, depending on the situation, chemotherapy can be combined with the goal of addressing the scattered cancer cells and preventing metastases from occurring.

Specifically, listen to the advice of the treating doctor.

Radiotherapy. What is the difference between chemotherapy and chemotherapy? Which works better? Let me now share my opinion. Surgery, radiotherapy, and chemotherapy are the most malignant tumors.

The three most traditional methods.

In short, chemotherapy is a systemic type of chemotherapy. Taken orally or intravenously.

It's like you have pneumonia.

Like an antibiotic infusion or antibiotic, chemotherapy drugs can enter various parts of the body and kill cancer cells throughout the body. Therefore, chemotherapy is a systemic means that can be used before surgery and is called neoadjuvant chemotherapy.

Before surgery, the lesion can be reduced, the difficulty of surgery can be reduced, and the rate of surgery can be improved. It is also possible to transform some inoperable patients into operable patients. Chemotherapy can also be used after surgery to kill cancer cells that are invisible to the naked eye, as surgery can only remove cancer cells within a certain range.

If cancer cells are hiding in the tumor's lymph nodes.

In the blood or other organs, it needs to be removed by chemotherapy.

Chemotherapy can also be used for palliative treatment of advanced tumors, tumors**, or systemic metastases**.

When surgery is not possible, chemotherapy is the main** method. Chemotherapy can kill cancer cells, shrink tumors, and improve survival. Radiotherapy is a local** method. Radiation**.

Utilize radioisotopes.

or radionuclides that release rays or particles to kill cancer cells. Thus, radiation** is somewhat similar to surgery**. It is a local attack.

For some tumors that are sensitive to radiotherapy, or the tumor is not well located, surgical resection is difficult, or the patient is too weak to tolerate surgery, radiotherapy can be considered instead of surgery to kill cancer cells.

Radiotherapy can also be used for postoperative radiotherapy in the surgical field to kill local cancer cells and reduce the local ** rate.

In short, radiotherapy is local** and chemotherapy is systemic**. These two approaches complement each other. Depending on the patient's condition, decide which ** method to use, or both.

The above is my difference between radiotherapy and chemotherapy? Which effect is better, I hope to provide some help to those in need.

Radiation therapy uses radiation, while chemotherapy uses chemical drugs. Radiotherapy is generally used for early and local effects, and chemotherapy is generally used for middle and late systemic drugs, which is relatively large.

Radiation therapy and chemotherapy. Radiotherapy means radiation**, and chemotherapy means chemical drugs**. For malignant tumors, some malignant tumors are more sensitive to chemotherapy and some are more sensitive to radiotherapy.

It cannot be generalized that radiotherapy or chemotherapy is better. If it is lung cancer, then chemotherapy and radiotherapy can be given at the same time.

Radiotherapy is to irradiate tumor cells through a large dose of radiation, resulting in DNA damage to cells and promoting apoptosis. Radiotherapy is local**, and the effect of local ** is often better. Chemotherapy is a systemic effect.

Radiotherapy is a kind of physical therapy, which mainly irradiates tumors through different energy rays to inhibit and kill tumor cells. Chemotherapy is mainly injected into the body through chemically toxic drugs through intravenous, oral, perfusion and other methods to kill tumor cells. Radiation therapy is more effective.

The difference between radiotherapy and chemotherapy lies in different methods, different ranges, different indications and different toxic and side effects. 1. Method: Radiotherapy is radiation, which is a local method, which is a method of irradiating tumors with various different energies to inhibit and kill cancer cells, commonly known as "roasting electricity"; Chemotherapy is a systemic malignant tumor using chemical drugs (including endocrine drugs, etc.).

Chemotherapy drugs are often introduced into the body intravenously, orally, or in other forms to kill tumors. 2. Scope: Radiotherapy and surgery are both local methods, and their scope is called the "target area", that is, the area where the rays are concentrated, and there are not many rays outside the target area.

After the radiation therapist determines the size of the tumor and the site of invasion based on imaging and other clinical examinations, it is also necessary to understand the biological characteristics of the tumor and the law of spread in order to determine the extent of radiation.

Radiotherapy refers to tumor radiation**, which is the use of radiation ** tumors;

Chemotherapy refers to chemical **, the synthesis of drugs with chemistry**. Its medication can be divided into six categories: alkylating agents, antimetabolites, antibiotics, plant alkaloids, impurities and hormones; It is a drug promotion for diseases caused by pathogenic microorganisms, parasites, and malignant tumors**.

The difference between radiotherapy and chemotherapy is that there are two important methods in the tumor, and the mechanism is different. Other adjuncts** (also for the cancer journey) can also be chosen, mainly to help relieve pain and improve quality of life.

Chemotherapy is a chemical drug**. Radiation therapy is radiation**. It's all the best way to get cancer.

First of all, let's talk about their respective meanings: chemotherapy, chemical drugs**, and also systemic methods**, which enter the bloodstream through injections or oral methods to kill cancer cells. Radiotherapy, which is a radioactive ray**, belongs to the local mode, which finds the lesion and uses radiation to irradiate it to achieve the purpose of killing cancer cells.

Either way, there is a big and strong ***, and the post-operative care is far greater than the surgery itself. Dr. Zhang Jun, the director of the oncology department of Shanghai Ruijin Hospital, wrote a lot of content to help the response of patients with radiotherapy and chemotherapy, which is enough to show the importance.

Chemoradiotherapy is indicated.

Radiotherapy is mainly aimed at relatively limited solid tumors, such as head and neck tumors, lung cancer, esophageal cancer, **cancer, lymphoma, etc.; Preoperative and postoperative adjuvant for some tumors**, such as breast cancer, cervical cancer, gastrointestinal tumors and adjuvant**; In addition, there are some tumors such as bone and brain metastases, palliative radiotherapy, etc., but for systemic tumors such as leukemia, the effect is limited. At present, about 70% of cancer patients need to receive radiation at different stages of the course of the disease, which shows the importance of radiotherapy in tumors**.

Chemotherapy is aimed at tumors that are sensitive to chemotherapy drugs, such as lymphoma, leukemia and other blood diseases, breast cancer, gastrointestinal tumors, lung cancer, reproductive system tumors, etc. The effect of chemotherapy depends on the type and condition of the tumor, and some can inhibit the growth and spread of the tumor. With the advent of new technologies, the indications for chemoradiotherapy are also changing.

What is the difference between radiotherapy and chemotherapy? There are three main points that many people often hear but can't tell the difference.

Radiotherapy is a method of irradiating tumors with various rays of different energies to inhibit and kill cancer cells. Radiotherapy is the use of radiotherapy instruments to focus on the tumor, to carry out the first time, is a means of local **, the current radiotherapy instrument upgrading, emphasizing the precise positioning of the patient, accurate, relatively small, the general patient can bear.

For cancer patients, chemistry and radiation are relatively common methods. Many people wonder which is better between radiotherapy and chemotherapy. The advantage of chemistry is that it can kill cancer cells and improve the survival rate of patients, but the disadvantage is that it can cause many ***.

The advantage of radiation** is that it can shrink the tumor and reduce the harm of surgery to the patient, and the disadvantage is that *** is too much. What are the specific differences and what are the specific advantages and disadvantages of chemotherapy and radiotherapy? Once a person has cancer, it must be timely**, the most commonly used clinical** methods are surgery, radiotherapy and chemotherapy, and many people do not know the difference between radiotherapy and chemotherapy and the advantages and disadvantages of each.

First of all, what we usually call chemotherapy is actually an abbreviation for chemical **, which is a method of synthesizing drugs specifically with chemical ** diseases. The advantages of chemotherapy are well known, whether it is a TV show or life, as long as someone has cancer, chemotherapy is basically needed.

This also shows that the effect of chemical ** is very good, although the effect of chemotherapy is very good, but *** is also great, but because chemical drugs cannot distinguish between enemies and themselves when killing cancer cells, they can also cause damage to normal human cells. There are a lot of drugs used in chemistry that are able to kill cancer cells, many of which are naturally grown, and these drugs have different effects on different patients.

There are also many people who use radiation to tumors, radiation is also one of the three cancer methods, radiation can inhibit and kill cancer cells It can be used alone, or it can be used together with surgery and chemistry, and the comprehensive effect is better.

The advantage of radiation** is that it can reduce the size of the tumor, some patients who cannot undergo surgery after radiation** can meet the surgical criteria and get the chance of surgery**, and patients with advanced cancer can also receive radiotherapy, which can relieve stress and reduce pain. Radiation, while it can bring good results, can also bring about it, such as weakness, tiredness, sweating, and drowsiness, as well as reduced immunity.

Chemotherapy is a drug, the use of drugs in the whole body to control the metastasis of cancer cells, a wide range, but chemotherapy drugs generally have toxic reactions, most of them affect gastrointestinal function and hematopoietic function, most patients will have nausea and vomiting, hair loss, white blood cells and platelet reduction, etc.

Radiotherapy, commonly known as electrotherapy, is a method that uses high-energy radiation to kill cancer cells, with a limited range but a better local control effect. Most of them are local reactions, blood changes, local mucosal reactions, etc.

Malignant tumors are mainly surgery**, chemotherapy and radiotherapy, chemotherapy is mainly chemotherapy drugs**, and radiotherapy is mainly radioradiation**. Gastric cancer needs to look at the stage of the tumor, in the early case, it is recommended that surgery has a better effect, if the advanced gastric cancer cannot be operated, chemotherapy, radiotherapy and targeted drugs can be selected to control the development of the tumor and prolong life.

Radiotherapy is a radioactive tumor, chemotherapy is a chemotherapeutic 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).

Radiotherapy kills tumor cells and also inflicts heavy damage on normal cells. Chemotherapy drugs and their metabolites are very harmful to normal cells, especially white blood cells, and metabolic organs such as liver and kidneys will also be under great pressure during the metabolic process. It can be alleviated by taking antioxidant and immune-enhancing things, such as ginseng egcg, as well as Chinese patent medicines that protect the liver, silybinin, schisandra, ganoderma lucidum, etc., and those who protect the kidneys can eat more tomatoes and pumpkin seeds.
