As the saying goes: "Tumor **, five years a hurdle".
Many people may have heard similar words, as long as there is no ** and metastasis for five years, the tumor is counted**. When it comes to the "five-year survival rate", many patients do not know about it. Someone else asked, "Is it possible that if you get sick, you can only live for 5 years?"”
To put it simply, the 5-year survival rate refers to the proportion of a tumor that survives for more than five years after various combinations. There is a certain scientific validity in expressing it in terms of five-year survival rate. In a study of nephrotic syndrome, the conclusion also suggested that if it is not ** within 5 years, the rate will be greatly reduced to a relatively safe level.
5 years may pass in a blink of an eye for normal people, but for cancer patients, it is of great significance, and it is difficult for most malignant tumor patients to cross the 5-year threshold.
Why is the concept of "5-year survival" chosen clinically instead of 1 or 3 years?
Clinically, the "5-year survival rate" is usually used to evaluate the long-term efficacy of tumors, which is mainly due to the fact that most tumors will metastasize or drug resistance progression or even die after comprehensive progression.
For tumors that can be resected by ** sex surgery, about 80% of ** or metastatic events occur within 3 years after ** sex surgery, and about 10% occur within 5 years after ** surgery, if ** metastasis does not occur 5 years after ** surgery, the risk and probability of ** again ** is very low, it can be regarded as clinical ** (but does not mean that there is no ** risk at all), therefore, the 5-year survival rate is often used to evaluate the efficacy of tumor **, and it is also convenient to compare the difference in efficacy between different countries and regions.
In addition, the 3-year disease-free survival rate is also commonly used in clinical practice to evaluate the efficacy, which refers to the proportion of patients who do not have metastasis within 3 years after surgery and are still alive, because most of the metastases occur within 3 years. This period of time is the peak period of tumors, and a slight carelessness will lead to the resurgence of cancer cells, so during this time, patients need to pay close attention to their physical changes, and at the same time do regular special examinations to prevent the risk of **.
After 3 years, the probability of tumor ** will be reduced accordingly, but it is still not to be taken lightly, the frequency of regular examinations can be extended, although it has survived the most dangerous stage, but there is still a great possibility of **, this period is a relatively stable stage, basically return to normal life.
5 years is very good news for cancer patients, and it is generally believed that the earlier the tumor is detected, the higher the 5-year survival rate after sexual surgical resection. For example, for colorectal cancer, the 5-year survival rate for stage I colorectal cancer is about 90%, the 5-year survival rate for stage II colorectal cancer is about 70%, and the 5-year survival rate for stage III colorectal cancer is about 50%. Tumor patients can basically be defined as "clinical**" after 5 years, although there is no guarantee that the tumor will not be ** at all, but one thing is for sure, after 5 years, the probability of tumor ** is relatively low!
How to prevent tumors**
The first is the aspect of resistance. Because tumor patients want to be the first to do not, the key is to restore their resistance, and because of all kinds of ** before, the resistance has decreased a lot, and they need to strengthen it bit by bit. Pay attention to the balance of nutrition when eating, melons, fruits and vegetables can not be left behind, so that three points of meat and seven points of vegetarian food.
Then it is to put an end to some bad habits, such as not smoking and drinking anymore, and regular and healthy work and rest if you usually like to stay up late. In addition, exercise is essential, which can not only enhance physical fitness, but also strengthen immunity, and can effectively reduce the probability of tumors.
To sum up, five years after the cancer patient's progression, it does not mean that they can sit back and relax, but there is a great hope that the tumor can be avoided and can return to normal life. Finally, cancer patients should also actively do something to reduce their tumor ** chance as much as possible, it is worth mentioning that for tumor patients, regular examinations are best not to be left behind.
