A decade or so ago, cancer was a “demon” far away from us, but nowadays, the increasing incidence of this disease has forced people to pay attention to it. Although cancer is no longer directly equated with death due to the increasingly developed medical technology, there are still many people who are afraid of talking about cancer. Should cancer patients undergo surgery? For those who are unfortunate enough to have cancer, they often have to face the question, “Should they undergo surgery or conservative treatment?” Although doctors will provide some professional advice, for patients and their families, answering this question may take into account other factors, and for the general public who do not know much about medicine, it is like playing an unsure game. Experts:It depends on the patient’s condition Many years ago, when the development of cancer was still a small probability event, people’s understanding of it was that it must be eradicated. However, with the advancement of medicine and the increase of cancer incidence, more and more people realize that removing the cancer development site is no longer the only method, and there are many cases, especially in the middle and advanced stages of cancer, which even deteriorate as soon as surgery is performed. On the contrary, the conservative treatment without much effort can ensure the patient’s quality of life to a certain extent for a certain period of time. The relationship between human and cancerous masses does not necessarily have to be a deadly one, but can even coexist peacefully for a long period of time, which has become a consensus in the medical field and is gradually accepted by the public. In addition, there are cancers that are not suitable for surgical treatment, while radiotherapy or chemotherapy may be more effective; there are cancers whose physical condition determines that they are not suitable for surgery, and if they insist on surgery, they may be aggravating the disease. Then there is the emergence of various advanced treatment technologies, which also provide more options for cancer. However, expert opinions are sometimes divided. Surgeons tend to favor surgical treatment, while internal medicine doctors and herbalists tend to advocate conservative treatment, which often leaves patients feeling at a loss. However, for some diseases with distinctive features, the mainstream medical community still has a relatively unified view: for example, lung tumors of the same size are more unsuitable for surgery if they are located in the middle than if they are located a little bit to the side, and they are even more unsuitable for surgery if they are old and frail, and if they are accompanied by other diseases; for example, for early stage small liver tumors less than three centimeters in diameter, doctors generally recommend surgery because the possibility of cure is relatively high, while for tumors larger than five centimeters in diameter, some doctors recommend surgery. For example, for small liver tumors less than 3 cm in diameter, doctors generally recommend surgery because the possibility of cure is relatively high, while for those larger than 5 cm in diameter, some doctors think that surgery may be more than worthwhile.
