How does cancer arise and how can I know if I am healthy?

Cancer, also called malignant tumors, is relatively benign tumors. Tumor refers to the local mass formed by the abnormal proliferation of cells in local tissues under the action of various tumorigenic factors. Benign tumors are easy to remove, generally do not metastasize, do not **, and only have a squeezing and blocking effect on organs and tissues.

However, malignant tumors can also destroy the structure and function of tissues and organs, causing necrosis and hemorrhage combined with infection, and patients may eventually die due to organ failure.

The basic unit of a cancer lesion is the cancer cell. After the aging and death of human cells, new cells will replace them to maintain the body's functions. It can be seen that most cells in the human body can proliferate, but this proliferation is limited, while the proliferation of cancer cells is endless, which makes the nutrients in the patient's body be consumed in large quantities.

At the same time, cancer cells can also release a variety of toxins, causing a series of symptoms in the body. If it is not found in time, it can also be transferred to all parts of the body to grow and multiply, and finally lead to emaciation, weakness, anemia, loss of appetite, fever and impaired organ function.

Almost every part of the body can be affected by cancer. Originally, the human body is a biological machine that works seamlessly, but cancer has changed that, and its task is to destroy. If it continues, it will bring down the human body.

However, unlike a virus, a tumor is not an invader outside the body, and its composition is the same as that of normal tissue, so the body cannot recognize it for immunity.

It is the result of abnormal growth and reproduction of cells in the human body. The human body has trillions of cells that make up various tissues, such as muscles, bones, and tissues. Normal cells grow, multiply, and die according to signals in the human body.

If this process is balanced and orderly, the human body will be healthy. When normal cells are mutated or changed, something goes wrong with the body, which is what we call a tumor.

If the tumour cells injure the surrounding normal cells and invade other parts of the body through the blood circulation, it is called a malignant tumor, which is commonly referred to as cancer. The biggest threat of a malignant tumor is its ability to metastasize to various parts of the body, and gradually, as the tumor expands, normal cells die, organ function fails, and eventually the patient dies.

Because the occurrence of cancer is affected by many factors, such as radioactive light exposure, viral infection, etc., and at the beginning of the appearance, only a lump appears on the body, or occasionally abnormal bleeding in the body, so many people do not care, and the longer it drags on, the more it is finally detected as cancer.

Because some people look healthy on the surface, they don't have healthy eating habits at all, and they don't pay attention to health preservation, so they will be diagnosed with cancer.

Because some people's bodies look relatively healthy, some cancer cells have already spread, so they will be detected.

Ordinary physical examination will not find cancer, mainly some blood pressure, blood tests, can only find some chronic diseases.

I think that most cancers are found to be at an advanced stage, but the manifestations are particularly obvious, and it is definitely difficult to detect them by ordinary examinations.

Usually, these cancers have some incubation period that is difficult to detect, and it is too late to detect them

Nowadays, most of the cancer diseases are found to be at an advanced stage, and it is difficult to detect cancer with ordinary examinations, so we must do more comprehensive examinations on a regular basis.

Cancer will not be detected by ordinary examinations, and cancer can only be detected by a special CT scan.

Cancer is caused by a cell lesion, so it is difficult to know the cause of the lesion, and it can be detected abnormally by ordinary examinations.

I don't think you can detect cancer by ordinary examinations, and if you want to check for cancer, you should do a more comprehensive examination.

At the level of modern medicine, cancer can also be detected by ordinary physical examinations.

There are generally a variety of methods for cancer examination, and conventional imaging examinations such as X-ray examination, ultrasound CT, and various laparoscopy are the most reliable and convenient, and at present, as a cancer screening, blood can also be drawn to check 12 tumor markers

Human immunity is very low, and long-term exposure to high pressure and depression is in an irregular lifestyle, resulting in mutations in the cells in the body and devouring our normal immune cells.

There is no particularly good diet in life, and there is no particularly good life routine, and there will always be some junk food, which is why cancer will appear. Will smoke a lot, will drink a lot.

It will slowly emanate, and if you don't get a good **, it will eventually emanate into your own organs, and it will also emanate into your own blood, and you will die.

Stress is very high, and poor living habits can lead to some chronic diseases, but if you don't pay attention to it, it will slowly turn into cancer.

The answer given by experts is that the results of a single physical examination are not of long-term significance, and can even change within a few months, especially for oncological diseases.

Experts suggest that the standardized tumor physical examination includes three aspects: on the one hand, it is an examination for cancer prevention, such as a biliary patient over 45 years old, who should have regular abdominal ultrasound examination. On the other hand, screening for early-stage cancer, such as cervical smear cytology in women, can detect cervical cancer in a timely manner.

In addition, after a detailed diagnosis and physical examination by an experienced engineer to detect the cancer signal at an early stage, the national first-class new drug "wild crocodile blood capsule" should be taken in time to prevent deterioration and death.

1. Three routines: routine examination of blood, stool and urine can show signs of cancer, especially abnormal blood routine, which is likely to be a manifestation of hematologic tumor.

2. Liver and kidney function: the function of the liver and kidney can be detected, and patients with chronic hepatitis and liver cirrhosis must be checked.

3. Tumor markers: Commonly used are alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) and CA125, etc., which have indirect suggestive effects, but are not specific.

4. Chest X-ray: reflect the condition of the lungs, it is best to take both the anterior and lateral positions when taking the X-ray, and long-term smokers must check it.

5. B-ultrasound: abdominal B-ultrasound can detect the condition of various abdominal organs, patients with chronic hepatitis and liver cirrhosis must be checked, and pelvic B-ultrasound can understand the ovaries and appendages.

6. Mirror: People who have irregular long-term life, overeating, and bad eating habits must be checked.

I can't be sure, you have to observe the cancer cells, and the hospital will make mistakes, and you can't observe it yourself
