Why does cancer return? Why do some cancers recur after being cured?

Cancer can happen, but the rate changes over time. Generally, the time of cancer** and metastasis is within 3 years, accounting for about 80%, and about 10% within 5 years. If the cancer tumor does not ** within 5 years, the chance of ** again is very low.

Therefore, those critical illness insurance with an interval of 5 years after the second claim for cancer will be directly passed.

The life of cancer cells is particularly tenacious, and cancer cells are particularly easy to metastasize to other places, and sometimes cancer cells are not completely removed and will grow back, so it will **.

Because cancer is now medically speaking, there is no medicine that can completely cure it, like sometimes eating and drinking is not good, not taking medicine, not listening to the doctor's advice, it is also very easy.

Cancer may be followed by **, and the difficulty of the later stage will also increase, so after the appearance of cancer, you need to actively cooperate**, and you also need to avoid some undesirable factors, which can prevent cancer cells from reappearing, and many people do not notice some problems of avoiding undesirable factors, which may lead to a lot of unreasonable behaviors after cancer**, which will give cancer cells a chance to come back, but at this time, cancer cells will cause more serious harm to people's bodies. So why do most people still have cancer after it? What causes this? Let's talk about it.

Some bad lifestyle habits can lead to cancer ** after ** again**. In fact, some bad living habits in life will affect the best of cancer, and cancer patients also need to pay attention to their own maintenance, by improving their own living habits to improve their body, but many people will ignore the cultivation of living habits, after the occurrence of cancer, still maintain bad living habits, so this will also seriously lead to damage to human organs, but also more detrimental to physical health. <>

The difficulty of cancer cells will increase, and some cancers will also be cancer, because in the case of cancer, it may not be complete. Because cancer cells are uncontrolled, if the disease cannot be controlled in a reasonable way, then it will not be complete, and there will be a small number of cancer cells in the body, so it may be caused after cancer, which will create more opportunities for cancer cells to destroy physical health, so after getting cancer, we must highly cooperate with the doctor, and at the same time, we must completely kill all cancer cells to reduce the chance of cancer, which is also a very important point. But it's also very difficult. <>

Some patients' body resistance is very poor, so when their own immunity is weak, the disease will come to the door, and many people do not pay attention to the improvement of their own resistance, after a long time, the body's immune function is very weak, then it will naturally lead to a decline in the function of body organs, and if the later maintenance does not do a good job of their own resistance, it may also lead to cancer again, so if you want to improve the possibility of cancer, you need to improve your own immunity, Avoid preventing cancer cells from reappearing.

Because after the success of the cancer, although there is no cancer, the body environment is very suitable for the mutation and even development of cancer cells, which may cause cancer cells to produce again and cause the spread of cancer cells, which will lead to the cancer again; It is possible that the patient is not well maintained during the recovery period, and if the malignant tumor in the body is not completely removed during the surgery, it can also lead to this cancer**.

It's because their immune system isn't very strong. It is because the virus has invaded that the body's immune cells cannot play a role.

Because the cancer cells spread quickly, it is generally because they are not removed during surgery.

Although the cancer is **, there are still individual cancer cells left in the body, and the expansion rate of cancer cells is very fast, and it is difficult to completely remove it.

Cancer surgery generally only removes the original cancerous cells and some normal cells near the cancer cells, but it does not guarantee that all cancer cells can be removed, and other normal cells will also be at risk of becoming cancerous.

Mainly because it is not completely removed, or the immunity is weakened, and it may be a bad diet, it may lead to cancer again**.

The main cause of cancer** is that the cancer is not complete, resulting in cancer cells remaining in the patient's body. This is the leading cause of cancer**. Due to the different types of cancer, the symptoms are different for different cancers**.

Cancer has metastasized, mainly in invasive cancer, when cancer cells have penetrated the basement membrane to the submucosa. Cancer cells can invade the blood vessels and lymphatic vessels in the submucosa, and travel with lymphatic fluid or blood to surrounding and distant lymph nodes, and even distant organs to form metastases. These cancer cells in the blood or lymph are also the root cause of most cancers** and metastasis.

The reason why the cancer is **later** may be due to the weak immune function. Maintaining a strong immune function is the key to keeping the disease away, but many people do not pay attention to the improvement of resistance, and after a long time, the body's immune function is weak and the function of vital organs declines. This can lead to cancer**.

Cancer** is not complete. The patient's cancer cells have a strong ability to grow and reproduce, and the cancer cells will rapidly invade from the lesion site to the surrounding organs.

Surgery as the most widely used means, local resection is complete, but the metastatic characteristics of the patient's cancer cells determine the drop of cancer cells after the onset of the patient's cancer, resulting in the metastasis or proliferation of cancer cells from the peripheral blood vessels, lymph and other pathways, some patients in the 5 years after surgery metastasis rate or ** rate as high as 90%, except for some early and mid-stage cancers, most cancers are difficult.

Chemotherapy is the best means of the whole body, and it has a good effect on the patient's metastatic lesions or primary lesions, and radiotherapy has obvious effects on specific areas of the patient, but these two methods have obvious effects, which will greatly damage the patient's body function and normal cells while killing cancer cells, and can never completely remove cancer cells, so the cancer is not complete, resulting in cancer cells remaining in the patient's body, which is the most important or main cause of cancer.

2.The cancer constitution has not changed. Most patients have developed cancer through surgery, radiotherapy, or chemotherapy**, but the patient's own cell differentiation regulatory mechanism has not undergone fundamental changes, and the environment for cancer cells to grow and multiply still exists, resulting in the patient's cancer**.

3.Immunocompromised. Surgery, radiotherapy or chemotherapy** cancer leads to great damage to the body and autoimmunity, resulting in a small number of mutant cells in the human body can not be effectively suppressed, resulting in the formation of tumor cells and causing cancer in patients**.

First of all, on a spiritual level:

Family members are sick, and since they need long-term bed care, most of them are serious illnesses or incurable diseases. As a loved one of the patient, you should be full of expectations for the patient, but some diseases will hit you again and again, and even turn it into despair. My father was found to have high alpha-fetoprotein during a physical examination, so he secretly went to the hospital for an in-depth examination, and the result was cancer.

When he told me the results, he was calm, but I was like a blow to the head and couldn't breathe. Later, he was admitted to the hospital the next day, and after various examinations, he had surgery to remove the tumor and began chemotherapy. During this period, I went to the doctor to chat and ask what the prognosis was, and the doctor told me that at present, all the tumors have been removed, and all indicators have been normal.

When I heard this, I had a feeling that in a few months my dad would be completely **. But it backfired, and in the next two years, there was constant **, intervention, **, intervention. My expectations of my father** are getting smaller and smaller, and I only feel that I am slowly losing him, but I can't do anything, only constant anxiety and sorrow.

The last time, the doctor rejected the ** to the father because there was no longer a sense of **. However, at this time, the mother who was admitted to the hospital for examination due to poor blood was also diagnosed with cancer. It's really unfortunate for the family.

After learning all this, his father Oak Sun Gao returned home indifferently. On the day I was discharged from the hospital, I walked beside him and looked at his emaciated body, feeling unable to face such a reality.

Many cancers are possible**, but certain types of cancer are more susceptible, such as lung, breast, colorectal cancer, etc. The high incidence of these cancers is due to the fact that they tend to have no obvious symptoms in the early stage and are difficult to detect in time, which leads to the survival and spread of cancer cells in the body.

In addition, if the patient is not thorough or the patient's physical condition is poor, Haoye will also increase the risk of cancer.

1.The cancer constitution has not changed.

"Cancer" may sound alarmist, but it exists for people who have had cancer before. Although the cancer has been treated with surgery, chemotherapy or radiotherapy, the differentiation and regulation mechanism of the cancer patient's body has not changed much, that is, the environment in which the cancer cells can still survive still exists, so the cancer will metastasize.

2.Low immunity:

The immune system is a powerful messenger of our body to resist viruses, there are many cells in the normal human body every day that are constantly metabolizing, and genetic mutations will also occur, only a few "bad" mutant cells are not controlled, and will malignantly transform into tumor cells, and the body's immune system will monitor and eliminate these mutations in time.

However, after a period of chemotherapy, cancer patients not only kill tumor cells, but also cause damage to normal cells, so the patient's immune function is also harmed. Therefore, after cancer patients are cured, they must pay attention to improving immunity and repairing the function of the immune system.

3.Unhealthy lifestyle:

Some people have a "big heart", after suffering from cancer, they return to work and life, and feel reborn, but they still don't pay attention to their bodies, smoking, drinking, staying up late, etc., but these are an unhealthy lifestyle, and this will cause the growth of cancer cells and lead to cancer.

4.**Not thorough:

People often ask, "Can cancer cells be killed completely?" "Current medical treatment, usually by surgery, radiotherapy or chemotherapy**, surgery is to remove the kind of cancer cells that have formed a lump, ordinary chemotherapy and radiotherapy is to destroy adult "grown" cancer cells, but the effect on juvenile cancer cells is less, so there is the possibility of growth of small lesions.

When the patient is attacked again, these juvenile cancer cells are very likely to wake up and deteriorate into adult cancer cells, which is one of the reasons for cancer metastasis**.

Cancer patients should actively cooperate with doctors**, and after the completion of **, it is important to pay attention to maintaining a healthy life and strive to improve the body's immunity. Fuck off, Tumor-kun.

In clinical and life cancer is not uncommon, in fact, the reason why cancer appears is related to many factors, cancer has a lot to do with its own nature, we all know that there are many types of cancer diseases, some cancers grow very fast, and it is easy to metastasize in the body, so even if it is related to the hospital, it is easy to appear **phenomenon.

Of course, there is also a close relationship between the way of cancer, sometimes because of the limitations of the body, there is no way to remove all the cancer cells in the body, and some cancer cells in the body still exist, if after the cancer, cancer patients do not pay attention to the relevant care, the body's immunity is also declining, so it is easy to appear.

In fact, the ** of cancer is not only related to the nature of the body and the way of the patient, but also has a great relationship with the patient's physical condition, in daily life, many cancer patients are relatively old, the physical state is already relatively weak, although the disease has been controlled, but the body's immunity and resistance are constantly declining, in this case, it is easy to cause cancer.

Cancer seems to be formed by the growth of residual tiny tumor cells, mainly because the tumor cells are not completely killed. If the degree of malignancy of the tumor is high, it is easy to metastasize, and if the degree of tumor is low, it is rare** and metastasis. There is also the time of discovery, if it is found, it will not be ** and transferred.
