In recent years, the incidence of tumors has been increasing year by year due to factors such as poor lifestyle habits and the continuous improvement of diagnosis level. However, with the improvement of medical standards, the treatment of tumors has also made great progress.
Surgery is currently the main method of cancer treatment, but there is some disagreement about surgery, except for those who believe that surgery can better remove tumor tissue, others feel that surgery is unreliable.
For example, some people are worried that surgery will break the tumor, and then the cancer cells will spread faster and then cause metastasis, so will this happen?
There are several reasons for the metastasis and spread of cancer cells, the most common of which is the characteristics of the tumor cells themselves. Cancer cells are extremely multiplying and aggressive, and can quickly spread to surrounding tissues or organs.
In addition, the microenvironment inside the tumor also promotes the metastasis and spread of cancer cells. For example, the lack of oxygen and acidic environment inside the tumor can stimulate the spread of cancer cells to surrounding tissues.
At the same time, cancer cells also affect surrounding cells by releasing a variety of growth factors and signaling molecules, thereby promoting their own spread.
In addition, the stimulation of external factors will also accelerate the metastasis and spread of cancer cells. For example, suppression of the immune system, inflammatory responses, mechanical stress, etc., may promote the spread of tumor cells. Stimulation by these external factors may alter gene expression in tumor cells, making them more aggressive.
In addition, some unhealthy lifestyle habits and environmental factors may also increase the risk of cancer, such as smoking, alcoholism, environmental pollution, etc. These factors may cause genetic mutations and abnormal cell growth, which can promote the spread and metastasis of tumor cells.
When facing surgery, many patients are worried about whether the tumor will be accidentally damaged during the surgery, which will lead to the spread and metastasis of cancer cells
This concern is quite legitimate, because once the tumour is broken, there is a risk that the cancer cells will spread from the primary site to other sites, which can worsen the disease.
First of all, we need to understand that surgery itself is an invasive operation, and no matter how skilled the doctor is, it cannot completely avoid damage to the tumor during the operation.
However, doctors try to protect the tumor as much as possible during surgery so that it doesn't break. They use a variety of surgical tools and techniques to minimize damage to the tumor, while also taking steps to prevent the spread and metastasis of cancer cells.
Secondly, modern medical technology has been very advanced, and doctors will perform detailed examinations and evaluations before surgery to determine the size, location, and adjacency of the tumor to the surrounding tissues.
With this information, doctors can develop a more precise and safe surgical plan, thereby reducing the risk of tumor damage and cancer cell spread during surgery.
Finally, it is important to understand that even if the tumor ruptures during the surgery, the doctor will take appropriate measures to deal with it.
For example, surgery is followed by adjuvant therapy such as radiotherapy and chemotherapy to kill cancer cells that may have spread, while the patient's condition is closely monitored and tracked.
Among the ** tumors, those cases that can be removed by **sexual surgery, there is about 80% of the ** or metastasis threat, concentrated in the 3 years after **surgery.
In addition, about 10% of the ** or transfer risk occurs within the 5-year period of ***. If, 5 years after surgery, the tumor has not appeared** or metastasized, the chances of recurrence are greatly reduced.
People often say "5 years not **" is also known as 5 years of disease-free survival. If the patient does not develop ** within 5 years after surgery and is still alive and healthy, then from a clinical point of view, it can be considered **.
When doctors refer to the 5-year survival rate, they do not mean that the patient will only survive for 5 years, but that he will survive more than 5 years.
The higher the 5-year survival rate, the better the cancer effect;If it is not ** within 5 years, it not only shows the effect of **, but also reflects that the malignancy of the tumor is low, and the possibility of ** is greater.
The time it takes for cancer cells to metastasize and spread varies depending on a number of factors and is uncertain. Generally speaking, cancer cells enter lymphatic vessels or blood vessels from the primary site and need to go through processes such as invasion, endosmosis, and extravasation.
These processes are influenced by a variety of factors, such as the type of cancer cells, the degree of differentiation, the rate of growth, the route of spread, etc. In addition, the body's immune system, genetic factors, environmental factors, etc., can also affect the rate of spread of cancer cells.
Generally speaking, it takes time for cancer cells to grow and multiply in a suitable environment. As a result, cancer cells can spread from the primary site to other sites, which can take months, years, or even longer.
However, if the cancer cells have spread to other sites, the disease progresses more quickly because the cancer cells multiply in the new environment and form new lesions.
Therefore, early detection, early diagnosis, and early ** are essential for cancer patients. Through timely intervention and intervention, the progression of the disease can be effectively controlled and the survival of patients can be prolonged. At the same time, patients also need to maintain a positive attitude and cooperate with the doctor's ** and advice in order to get the best ** results.
