Chemotherapy is one of the most important means of cancer in modern medicine, which uses the characteristics of continuous blood circulation and flow of chemotherapy drugs to various organs and tissues of the body through oral or injection of chemotherapy drugs.
These chemotherapy drugs can effectively kill cancer cells, so as to achieve the goal of ** cancer. However, chemotherapy is not a perfect way.
The biggest problem is that in the process of destroying cancer cells, chemotherapy drugs will inevitably damage normal cells, triggering a series of uncomfortable reactions.
Cancer is a complex disease, and its progression and symptoms vary from individual to individual. When cancer is first diagnosed, some patients are able to eat and sleep, probably because the cancer has not yet had a significant negative impact on the patient's body. At this time, the patient's physical condition is relatively good, he can eat and sleep, and his mental state is also better.
However, when the cancer begins to receive**, the patient's physical condition may change. Drugs and radiotherapy in the process will cause certain problems such as nausea, vomiting, fatigue, etc. These *** can affect the patient's appetite and sleep quality, causing the patient to feel unwell and even worsen the condition.
In addition, the psychological stress in the process can also affect the patient's physical condition. Cancer** is a long and arduous process, and patients may experience negative emotions such as anxiety, fear, and restlessness. These emotions can affect the patient's body immunity and make the patient more susceptible to the invasion of the disease.
Lesion remission
If chemotherapy is effective, there are usually some positive signs. First of all, through imaging examinations such as B-ultrasound, CT, and MRI, it is possible to clearly observe whether the tumor has shrunk.
These imaging tests are the most straightforward way to assess changes in the size of the tumor, and if you notice that the tumour is gradually getting smaller, then this is a very good sign.
Tumor markers are declining
After chemotherapy, blood tests can be done to measure the levels of tumor markers. If the level of tumor markers decreases significantly, then it usually means that the chemotherapy drug is effectively attacking the tumor cells. In addition, if tumor marker levels remain consistently within the normal range, this may also mean that chemotherapy is working well.
Symptom relief
For example, if a tumor is pressing on a nerve causing pain, a decrease in pain after chemotherapy may mean that the tumor is shrinking. Similarly, if a patient with esophageoma has remission of dysphagia after chemotherapy, this may also be a sign that chemotherapy is working.
Advanced cancer refers to the malignant tumor that has spread to multiple parts of the body and cannot be completely treated by surgery, radiotherapy, etc. In this case, the main purpose of ** is to control the condition, relieve symptoms, and improve the quality of life of the patient.
Chemotherapy is an important means of advanced cancer, which kills cancer cells or stops them from growing through chemical drugs, which helps to control the disease, relieve symptoms, and prolong the survival time of patients.
Although the rate of patients with advanced cancer is low, chemotherapy is still an effective modality. First, chemotherapy can reduce the size of tumors, reduce patients' symptoms, and improve quality of life.
Secondly, chemotherapy can prolong the survival time of patients, especially in some types of cancer, such as ovarian cancer, ** cancer, etc., chemotherapy can significantly prolong the survival time of patients.
In addition, chemotherapy can also be used to control the metastasis and spread of cancer. Although chemotherapy cannot completely stop the spread of cancer cells, it can kill a large number of cancer cells, reducing the likelihood of metastasis, thereby prolonging the survival of patients.
Of course, there are some ***s and risks associated with chemotherapy. For example, chemotherapy drugs may cause damage to normal cells, causing symptoms such as nausea, vomiting, and fatigue. However, the doctor will develop a ** plan according to the specific situation of the patient to minimize *** and risk as much as possible.
