The arrival of cancer is always unexpected. Although there is no discomfort or abnormality in your body, you will be "stopped" one day - it will be a late stage of cancer after checking.

The arrival of cancer is always unexpected. Although you don’t have any discomfort or abnormalities in your body, you will be "stopped" one day - Check it out means advanced cancer .

A cardiopulmonary surgeon who has been in medicine for more than 20 years personally recorded the process of suffering from lung cancer:

One day, after completing a surgery, he felt dizzy and his face twitched a little. He was about to go to the bed to sleep for a while, but he fainted after getting up.

Unexpectedly, after waking up, I got a test report of "latest stage lung cancer".

As a lung cancer expert who has been in the industry for more than 20 years, he usually treats lung cancer patients, but now he has become a lung cancer patient. Generally, lung cancer has some signs of precursor, such as severe dry cough, blood in the sputum, etc. But looking back, there is no exception .

Fortunately, after 8 months of conservative treatment, the tumor in the doctor's lung miraculously "disappeared".

But not everyone thinks that this doctor is as "lucky". Many people are late-stage when they find out that cancer is extremely poor, and they die shortly after treatment. Why do some cancers still "no pain or itch" when they reach the late stage?

1. Why does the cancer reach its late stage without any symptoms?

Generally speaking, cancer usually does not have any symptoms in the early stages of cancer, and most people are accidentally diagnosed during routine physical examinations.

Until the development reaches the late stage and the tumor becomes larger and it will compress or invade the adjacent tissue, will not experience a series of symptoms such as anorexia, weight loss, pain, burnout and constipation.

In fact, this is related to the characteristics of cancer cells. Everyone has cancer cells in their body. Cancer cells are essentially "harmless" and the body will not cause too many reactions because of its appearance.

Early stage of cancer, cancer cells proliferate relatively slowly . Although the immune system will be activated and some cancer cells will be eliminated, the intensity of this process is very low and not very specific, so the body cannot sense the cancer cells and distinguish them from other normal cells.

Moreover, the early tumors of are relatively small and will hardly affect the normal function of the body . In addition, the compensation function of some organs is very powerful, which causes some cancers to develop into the middle and late stages, and there will still be no obvious symptoms.

However, once the cancer cell proliferation speed accelerates and the number increases greatly in a short period of time, exceeding the load of the immune system, many negative effects will be produced, such as excessive consumption of nutrients in the body and destruction of important organ tissues, which will eventually lead to the patient's death due to malnutrition, organ failure and complications.

In addition, many people have advanced cancers as soon as they are discovered, which is also related to these two factors.

• neglected to diagnose and treat

Early symptoms of some cancers are not specific and are easily confused with the symptoms of other diseases. In addition, many patients often neglect diagnosis and treatment, or although they found abnormal indicators during physical examinations, they did not go to the hospital for further examination to clarify the cause, so they missed the treatment opportunity.

• date of physical examination
Many people think they are healthy and are unwilling to have regular health examinations, but in fact, some early lesions of cancer can be discovered through routine examinations. For example, Pap smear in routine gynecological examinations can detect early cervical cancer.



2. Four types of cancers do not hurt or itch when they come. Prevent

In fact, most cancers do not have specific symptoms in the early stage when they come, which is often easy to ignore. Especially for these types of cancer, everyone should be vigilant.

• , pancreatic cancer

  If you have inexplicably persistent abdominal pain or back pain, and feel stuffy in the upper abdomen, but you don’t find any problems when you do gastroscopy or liver and gallbladder ultrasound, and you have not dieted but lose weight, you should highly suspect that it may be pancreatic cancer.

, Naropharyngeal carcinoma

Early nasopharyngeal carcinoma symptoms are not obvious and are often difficult to detect. If some cold symptoms (such as runny nose and coughing up phlegm) are always not cured, or people who rarely catch colds suddenly continue to catch a cold, or inexplicably and bleed , you should be wary of the possibility of nasopharyngeal cancer.



, lung cancer

If you have the habit of smoking and suddenly have a long-term cough that cannot heal, you should be alert to the possibility of lung cancer. Don’t wait until symptoms such as coughing up sputum and blood, dysphagia or chest pain are present before going to the hospital for examination, because lung cancer is often in the late stage at this time.

, kidney cancer

• The kidney is located in the back of the abdominal cavity, and there is a large space here, making it difficult to detect early kidney-related lesions. If you experience hematuria , low back pain, or lumps in your abdomen, be careful that it may be kidney cancer.

  

  3. Is cancer screening necessary? 2 points are very important

  Some cancer patients may think that they have regular physical examinations every year, and the results are normal, so why does cancer still occur? Is the so-called cancer screening a fraud?

  A regular examination once a year cannot detect all abnormalities. If the lesions are still small, the examination methods are inappropriate, or the examiner has insufficient experience, early cancer may not be detected. This is why the annual physical examination indicators are normal, but once the result is confirmed, it is advanced cancer.

  is different from routine physical examinations. . Choose cancer screening items in a targeted manner. Especially these two points:

  . You need to choose a special : . There are many anti-cancer physical examination packages, but the more and more expensive it means the better. You need to choose a special anti-cancer screening for the type of cancer you want to screen.

  You should choose the that suits you: Everyone is different, whether it is family history, eating habits, living environment and working environment, the high-risk factors of cancer and the risk of cancer associated with will naturally be different. Therefore, the physical examination plan for screening cancer also varies from person to person.

  

  How should I choose the examination items for different cancers?

  • lung cancer

  Screening items: Low-dose spiral CT (LDCT)

  Check frequency: once a year.

  • gastric cancer

• Screening item: gastroscopy is the first choice, followed by Helicobacter pylori, gastrin and pepsinogen

  Inspection frequency: After the first gastroscopy is received, once every 2-3 years.

  

  • esophageal cancer

  Screening items: Endoscopy

  Examination frequency: After receiving the first endoscopy, if there is no abnormality, it will be once every 2-3 years, and if there is any abnormality, it will be once a year.

  • colorectal cancer

  screening item: the first choice is colonoscopy and fecal occult blood test, followed by gene detection and tumor marker

  examination frequency: After the first colorectal cancer screening , colonoscopy is every 5-10 years, and stool occult blood test is 1 year.

  

  • Breast cancer

  Screen items: Breast ultrasound, breast X-ray

  Check frequency: once a year or once every 1-2 years.

  • hepatoma

  Screening items: serum alpha-fetoprotein detection, abdominal ultrasound examination

  examination frequency: once a year.

  

  cancer cells are highly occult, which leads to many cancers without obvious symptoms in the early or even late stages. In addition, some people are afraid of medical treatment, so it is easy to have a late stage when they are diagnosed.

  So for cancer, early screening, early diagnosis and early treatment are really important.
