How long can a person with advanced pancreatic cancer metastasize to the liver and lungs live?

Cancer, also known as malignant tumor, is different from benign tumor. Tumor refers to a local mass formed by abnormal proliferation of cells in local tissues under the action of various tumorigenic factors. Benign tumors are easy to remove and generally do not metastasize or recur. They only have squeezing and blocking effects on organs and tissues. However, malignant tumors can also destroy the structure and function of tissues and organs, causing necrosis, bleeding and infection. Patients may eventually die from organ failure.

The basic unit of cancer is cancer cells. When human cells age and die, new cells will replace them to maintain the body's functions. It can be seen that most cells in the human body can proliferate, but this proliferation is limited, while the proliferation of cancer cells is endless, which causes a large amount of nutrients in the patient's body to be consumed. At the same time, cancer cells can also release a variety of toxins, causing a series of symptoms in the human body. If it is not discovered and treated in time, it can also spread to various parts of the body to grow and reproduce, and finally cause the body to become emaciated, weak, anemic, lose appetite, have a fever, and damage organ function.

Almost every part of the human body can be invaded by cancer. Originally, the human body, a biological machine, runs perfectly, but cancer changes this situation. Its mission is to destroy. If it continues, it will drag down the human body. However, tumors are not like viruses, they are not foreign invaders. Their components are the same as normal tissues, so the body cannot recognize and immunize against them.

High-dose radiotherapy and chemotherapy for patients in the middle and late stages, or chemotherapy again for patients who have developed drug resistance, can only make the weak life more critical and accelerate the patient's death. It is often seen in the clinic that the cause of death of patients is not caused by the cancer itself, but by unscientific and inappropriate lethal treatment. For example, after multiple interventions for liver cancer, ascites, jaundice and other liver failure occurred, leading to death; lung cancer died of respiratory failure after chemotherapy caused by pleural effusion; nausea and vomiting after chemotherapy for gastric cancer and intestinal cancer, and patients died of further failure; white blood cell count decreased, and patients died of infection, etc. Severe toxic side effects such as leukocytosis, mainly manifested as dizziness, dilated pupils, nausea, vomiting, diffuse abdominal pain, muscle weakness, etc. In severe cases, bradycardia, cardiac arrest or death may occur! Not to mention cancer patients! Cancer patients have low resistance and weak bodies, and taking it alone would be even more dangerous! It can make up for the deficiencies of surgical treatment, radiotherapy, and chemotherapy. It can not only consolidate the effects of radiotherapy and chemotherapy, but also eliminate the toxic side effects of radiotherapy and chemotherapy. More importantly, it can cut off the replication function of cancer cells, that is, cut off the synthesis of microtubules, an important division square of cancer cells, so that the cell volume gradually shrinks, and stable anti-cancer cells are formed in the blood vessels, thereby improving the body's metabolic function, that is: by inhibiting the respiration of cancer cells, causing ischemia and hypoxia of cancer cells, and no longer fissioning, thereby achieving the purpose of curing cancer.

Radiotherapy is a treatment method that uses high-energy electromagnetic radiation to act on living organisms to change the structure of biological molecules and destroy cancer cells. Radiation can treat cancer because cancer cells are sensitive to radiation. Currently, there are two types of radiation used clinically: X-ray therapy and r-ray therapy.

Whether radiotherapy is effective for cancer depends on many factors, such as the early or late clinical time, the pathological type of the tumor and its sensitivity to radiation, the patient's overall condition and the situation around the tumor.

The effect of radiotherapy is very poor, such as some soft tissue sarcomas and bone tumors. The radiosensitivity of tumors is also related to their growth pattern. Generally, tumors that grow outward, such as papillary, polyp, and cauliflower types, are more sensitive, while tumors that grow in an infiltrative manner, such as infiltrative and ulcerative types, are less sensitive.
