Which cancer patients are not candidates for radiotherapy? What types of tumors does radiation thera

Radiotherapy is a method of controlling the malignant transformation of tumors, which can help patients prolong their lives and improve their quality of life, but not all tumors can use radiotherapy, radiotherapy is also a means of cancer, and the range of use is very wide, many cancer patients will use radiotherapy to control the disease, but some cancer cells are not very sensitive to other treatments, so they cannot achieve the desired curative effect, so some cancer patients are not suitable for radiotherapy, so let's discuss it together. Which cancer patients are not suitable for radiotherapy? <>

Worsening cancer. Because chemotherapy has a lot of problems, some patients' tissue cells will also be damaged by chemotherapy, so if there is severe chemotherapy damage, chemotherapy can no longer be performed, because it is easy to have radiation damage, and there is not much benefit to the patient. In addition, chemotherapy is not recommended for tumors with obvious malignant transformation, because after the tumor progresses, the body will experience severe dehydration and anemia, so it is necessary to wait until the body has recovered to a certain extent before chemotherapy can be performed.

Radioinsensitive tumors are also not candidates for chemotherapy. Chemotherapy is suitable for all tumors and cancers, but some tumors are not very sensitive to radiation, and if they are not sensitive, they will affect the effect, but will not remove all cancer cells, and it is likely to cause the increase of cancer cells again after the disease, so for tumors that are not sensitive to radiation, if chemotherapy is used, the effect is not obvious, and it will even lead to radiation damage. <>

Patients with metastases. Radiotherapy is targeted at local tumors, but the problem of tumor lesions with a large range cannot be solved, because the process of radiotherapy will also damage normal cells, but the problem of carcinogenesis in a larger range is not able to choose radiotherapy**, although there is a certain effect, but the harm to the body is greater, so in general, radiotherapy can not be carried out on patients with metastasis. <>

Radiotherapy itself has a certain amount of harm to the body, so it is necessary to treat radiotherapy rationally, if there is a patient with serious disease and needs to control the condition at an early stage, you can choose radiotherapy, but you still need to judge according to your actual situation and carry out it according to the doctor's guidance.

The effect of radiotherapy on tumors is still very large, and most of them are suitable for radiotherapy, but patients with large gastrointestinal, gallbladder, spinal cord and diffusion locations are not suitable, because it may cause gastric bleeding, the effect is not obvious, and severe paralysis may occur.

For patients who are sensitive to radiotherapy, patients with cancer cachexia are not suitable for this type of radiotherapy, because their bodies are very weak, and the cancer has metastasized in multiple places, and radiotherapy is not of great significance; For some esophageal cancers, cancers with complications are not suitable for radiotherapy**.

People with poor physique, people who have metastasized, people who are sensitive, people who are prone to bleeding, these people are not allowed. For example, melanoma , small bowel cancer, stomach cancer, osteochondrosarcoma.

This should be determined according to the physical condition, under normal circumstances, benign patients do not need to be like this, different tumor states are different, so there is no way to judge which tumors radiotherapy has a relatively large effect.

Radiotherapy is an important means for cancer patients, and 70% of patients need to undergo corresponding radiotherapy in the process. In the process of the patient**, the radiation will kill the cancer cells in the body, which belongs to a local**. If people have a wide range of tumors, then surgery is not possible**, and radiation therapy can regress the tumor.

Radiotherapy will irradiate not only the tumor site, but also the site that may spread, which can achieve a good control effect and can effectively prevent cancer**. <>

When people are in the early stage of cancer, middle cancer or middle and advanced stage of cancer, they may be treated with radiotherapy, which will produce a certain amount of radiation in the process, but the impact is not very large, and within the controllable range, after the correct treatment, people's symptoms can be alleviated. Cancer has always been a disease that distresses many people, **cancer methods include radiotherapy, surgery**, chemotherapy**, immuno**, targeting**, etc., radiation** has less damage to body tissues and organs, so it will be used as a preferred plan. <>

If people's condition is more severe, then it can also be combined with radiation** and surgery**, which will allow the tumor to be well controlled. With the continuous improvement of people's quality of life, the incidence of malignant tumors has gradually increased, and it has become the second largest killer of people's health. Under the scientific condition of the doctor, the patient can be cured, and the cancer cells in the body will be controlled and killed in time, which will not have much impact on people's bodies and will not affect people's quality of life.

The tumors that can be treated with radiotherapy include nasopharyngeal cancer, head and neck tumors, esophageal cancer, small lung cancer, abdominal tumors, malignant lymphoma, cervical cancer, prostate cancer, etc. If people find out that they have such a disease, then they need to have a good attitude, they need to be actively involved**, they need to follow the doctor's instructions, and they need to not hide from the doctor. People need to have a good lifestyle in normal times, they need to prevent cancer in normal times, they need to pay attention to their daily schedule, they need to pay attention to their diet, and they need to achieve a balanced diet.

It can kill 80% of cancer cells. These include rectal cancer, stomach cancer, esophageal cancer, nasopharyngeal cancer, tongue cancer, and these are very effective.

The effect is still relatively large, which can inhibit the spread of cancer cells. Esophageal cancer, stomach cancer, liver cancer, lymphoma, oral cancer, cervical cancer, lung cancer, and many more.

It can achieve a good curative effect and can effectively avoid the spread of cancer cells. These include small cell, lung, stomach, colon, liver, breast, thyroid cancer.

The first type of cancer is lung cancer, the second type is breast cancer, and the third type is prostate. The fourth type is nasopharyngitis. The fifth type is head and neck cancer, and the sixth type is ** cancer.

7th seed cervical cancer. Radiotherapy is necessary to have a good recovery. And there will also be a healthy body.

Radiotherapy is a key life-saving treatment for lung cancer, nasopharyngeal cancer, cervical cancer and breast cancer, and it is also beneficial for relieving brain tumors, so radiotherapy is not useless.

Lung cancer, stomach cancer, liver cancer, intestinal cancer, laryngopharyngeal cancer, these cancers are very critical and can be relieved if they are timely.

Esophageal cancer, stomach cancer, uterine cancer, breast cancer, prostate cancer, these cancers are the key to life-saving in early radiotherapy.

Breast cancer, uterine cancer, esophageal cancer, prostate cancer, esophageal cancer, these cancers are the key to life-saving.

The first cancer, lung cancer, the first breast cancer, the first prostate. The first type of nasopharyngitis. The first type of head and neck cancer, the first type is ** cancer. Seed cervical cancer. Radiotherapy must be manipulated to perhaps have a very **. And also to have a healthy figure.

Here are a few common methods of radiation**.

Nolly knife radiotherapy.

Nolly Knife Radiotherapy** Lung Cancer has the advantages of no surgery, no bleeding, ** suffering, and no danger. The Nuoli Knife system has a number of leading technologies such as a more advanced automatic error correction and positioning system controlled by an intelligent robot, which makes the process of tumor progress into an intelligent and automated process. The Nuoli knife head is equipped with a multi-leaf grating, which is irradiated by a coplanar non-coplanar arc or fixed beam to focus the rays on the tumor area to achieve conformal irradiation.

Cyberknife and Gamma Knife.

Gamma Knife is the earliest stereotactic radiosurgery technology, rich in clinical cases, CyberKnife is the latest stereotactic radiosurgery technology applied in clinical practice, accurate positioning, respiratory tracking system can move with the movement of lung tumors, and will not accidentally damage the surrounding normal tissues, which is one of the most advanced radiotherapy technologies in clinical practice.

Conformal RadiotherapyThe photon knife in conformal radiotherapy is also the same as the Nuoli knife, which can be minimally invasive** for lung cancer. It uses the principle of stereotactic radiosurgery to replace a scalpel with high-energy rays and uses the radiobiological effects produced by the rays to destroy the lesions in the body.

It uses a three-dimensional planning system to reconstruct the image, and through a special module, the high-energy rays are spatially distributed in accordance with the size and shape of the tumor, so that the tumor target receives a lethal dose, thereby minimizing the damage to the surrounding normal tissue. It can greatly improve the local control rate of tumors, and also reduce the toxicity to a large extent.

The intensity-modulated radiotherapy system is suitable for general radiotherapy and precision radiotherapy for tumors in all parts of the body, and can be used for first-class radiotherapy for early tumors and palliative radiotherapy for advanced tumors according to the actual situation of tumor patients.

However, intensity-modulated radiotherapy has more advantages for tumors with complex anatomical structures, such as nasopharyngeal carcinoma, maxillary sinus cancer and intracranial tumors. or tumors with irregular shape and surrounding vital organs or tissue structures, such as lung cancer, esophageal cancer and prostate cancer; or multi-targeted tumors.

Radiotherapy is to inhibit the growth of cancer cells, but it may still be **, so it can't be said that it's okay, zolephosphate is to prevent further bone metastasis, and it is best to give chemotherapy. If you have a good doctor, you should also do Chinese medicine**.

Radiotherapy can relieve pain and avoid paralysis caused by tumor invasion of the spinal cord, and the benefits are greater than ***.

Breast cancer radiotherapy is the main way, but radiotherapy will have some ***, and a reasonable diet during radiotherapy can improve the effect and reduce some complications. To reduce the amount of radiotherapy, you can cooperate with traditional Chinese medicine, which can reduce the damage to organs caused by radiotherapy, stabilize the number of white blood cells, and improve the effect of radiotherapy.

life) (element).

Radiotherapy can inhibit the growth of tumor cells, and has the best effect on some tumors, but at the same time, it also has some damage to normal cells.

Hello For bone metastases, radiotherapy is definitely to be the first choice. At the same time, it is recommended to combine systemic chemotherapy and traditional Chinese medicine**. Bone metastasis is caused by the metastasis of cancer cells, which means that there are cancer cells in the blood, and metastasis to other parts of the body may occur, in this case, it is necessary to consolidate chemotherapy to kill the remaining cancer cells in the body.

At the same time, it is recommended to assist the application of traditional Chinese medicine to further control the disease and improve the patient's own disease resistance.

The first is the process of emitting some radiation through the machine, and then destroying and killing these tumor cells.

Radiotherapy is used to prevent the spread of cancer cells, and in this way, the symptoms are relieved and life is prolonged.

Through the process of radiotherapy, all viruses and toxins in the patient's body are radiated, which can help the patient to relieve pain.

There are nasopharyngeal cancer, head and neck cancer, ** cancer, cervical cancer, and bone marrow cancer. If you have these cancers, radiation therapy is really the key to saving lives.

Prostate cancer, cervical cancer, breast cancer, lung cancer, nasopharyngeal cancer, stomach cancer, etc., these cancers can be treated with radiotherapy**.
