There is a saying in China: the roof leaks when it rains overnight, and the boat is late and the head wind is blown!
For cancer patients, cancer is already very unfortunate, and even more unfortunate is that cancer discovery is advanced!
In addition to this situation, there are even more unfortunate cases in the clinic. The patient had previously experienced cancer in one organ, but it didn't take long for the other organs to become cancerous again. Cancerous changes in other organs are not the metastases of the original cancerous organs, but the emergence of new carcinoma in situ in this organ, which is called in the clinic: secondary primary tumors!
So the question is, after the cancer, there is a new tumor again, what is going on?
A large number of studies have shown that if they have already developed carcinoma in situ of an organ, patients are more than 11 times more likely to have new carcinoma in situ than healthy people. In the Nearly 20 years since the United States, more than 8 percent of cancer patients have had a second primary tumor.
Among all cancer types, the highest incidence of secondary primary tumors is lung cancer, followed by gastrointestinal cancer. Compared with the first primary tumor, the mortality rate is higher, and nearly 50% of patients are dying due to the appearance of secondary primary tumors, worsening of the condition, complications, and organ failure.
The reason why cancer patients are more likely to have new cancerous changes is because the pathogenic factors of cancer are quite complex, and the current clinically applied cancer treatment methods are actually typical double-edged swords. For example, surgery, radiotherapy and chemotherapy, etc., they do clear the tumor, inhibit the proliferation and spread of cancer cells, but at the same time, they will also cause harm to the patient's body.
Chemoradiation, in particular, can damage the patient's healthy cells and cause damage to the immune system while treating.
Moreover, at present, in medicine, many times, it is a glimpse of the whole leopard, they only pay attention to the immediate treatment effect, but do not pay attention to the cascading effect produced in the later stage. To take a simple example, the currently commonly used drug "tamoxifen" to control breast cancer, long-term application will cause abnormal thickening of the endometrium and increase the risk of cancer.
However, the clinic does not abandon the use of the drug because of its side effects. Similarly, in other drugs used to treat cancer, phenomena similar to tamoxifen are more common.
Aside from the impact of cancer treatment, the saddest thing is that any clinical treatment is simply aimed at the control of the cancer itself. Even if the clinical cure is achieved, the genetic genes and tumor susceptibility in the patient's body have not changed.
In particular, in the population where genetic genes occupy an important factor in the patient's cancer, even if the carcinoma in situ has been treated and controlled, and clinical cure has been achieved. Because the physique has not changed, there will be cancer again in the later stage, but it is only a matter of time sooner or later.
In addition, poor living and eating habits have not improved, the living environment has not changed, the personality has not changed, etc., which will directly or indirectly affect the prognosis effect of patients, promote cancer recurrence, secondary primary tumors appear.
Finally, cancer patients should be reminded that the recurrence rate of cancer is quite high, and there is a risk of secondary primary tumors. Therefore, even if the cancer is controlled and clinically cured, patients should follow the doctor's recommendations and conduct regular targeted re-examinations to avoid cancer recurrence without knowing it. In particular, within 1 year after cure, follow-up examinations should be more frequent.
