Cancer: Does it mean that the tumor is at an advanced stage?

Hello landlord: Many of the above are actually inaccurate or incorrect.

In medical terms, cancer should belong to a large category of tumors. Tumors are a large group of diseases characterized by abnormal cell proliferation and metastasis. According to its biological characteristics, such as whether there is metastasis and whether there is invasion, it is divided into benign tumor and malignant tumor.

In malignant tumors, cancer occurs when it originates in epithelial tissue, and sarcoma occurs when it originates in mesenchymal tissue. However, in the public's propaganda, cancer is equated with malignant tumors.

Each disease can be divided into early and late stages. Take liver cancer as an example, if it is early liver cancer, the prognosis is still good under the system. However, if it is found to be at an advanced stage, the survival period is very short.

Therefore, we have always advocated regular health check-ups, especially after the age of 30, and regular health check-ups are necessary. Early detection, early ** is the best prevention of malignant tumors, the best**.

Tumors are usually divided into two categories: benign tumors and malignant tumors, and what people often call cancer is a general term for various malignant tumors. Strictly speaking, malignant tumors of the human body and mucosal tissues of certain organs (such as digestive tract and respiratory tract) can be called cancer, such as esophageal cancer, stomach cancer and lung cancer; Malignant tumors of other tissues are called sarcomas, such as lymphosarcoma and osteosarcoma. The incidence of cancer is much more common than that of sarcoma, so people often refer to malignant tumors as cancer.

What is cancer? Cancer is composed of cancer cells, there are about 2,000 trillion cells in the human body, under normal physiological conditions, they are all working in an orderly manner, according to a certain way and speed of continuous birth, growth, aging and death, very regular metabolism, in order to maintain the normal function of the human body. However, under the influence of certain conditions (radiation, viruses, molds, physical and chemical factors, etc.), some cells grow blindly and develop freely without any restrictions, and their growth rate is much faster than that of normal cells, thus consuming a lot of nutrients in the human body, and these malignant proliferating cells are called cancer cells.

The rapid proliferation of cancer cells and special metabolic processes destroy the structure of tissues and organs in the human body, causing them to lose their function. For example, in the alveoli of lung cancer patients, due to the congestion of a large number of cancer cells, the lung tissue is destroyed, and finally the patient's lungs lose their respiratory function.

In the advanced stage of liver cancer, you can only live for two months.

However, cancer is divided into early and advanced stages, and the early stage is easy to control.

Cancer is a malignant tumor.

For advanced cancers, chemotherapy that can prolong life by controlling the growth, development and spread of tumors through chemotherapy, radiotherapy, immunology**, targeted drugs**, biological**, etc., is certainly useful.

Is malignant tumor an advanced stage of cancer, in this era of advanced science and technology, many people still suffer from diseases, malignant tumors are one of them, so is a malignant tumor an advanced stage of cancer, can it still be **, then follow my footsteps, let's learn about the relevant knowledge.

Is a malignant tumor an advanced stage of cancer?

Tumors are not necessarily cancers, there are two types: benign and malignant. Benign tumors generally develop slowly, they are mainly expansive, have an intact capsule, do not metastasize to distant sites, and do not infiltrate into the limbs.

However, malignant tumors generally grow infiltratively and metastasize distantly along blood vessels and lymphatic vessels.

Can malignant tumors metastasize cancer be treated at an advanced stage?

1. **Sexual surgery:Because the malignant tumor grows quickly, there is no capsule on the surface, it has no obvious boundary with the surrounding normal tissue, and it is highly locally infiltrated and can metastasize through lymphatic vessels. Therefore, surgery involves the complete removal of the tumour and a certain range of normal tissues around it and lymph nodes that may be invaded.

This surgery is suitable for patients with limited tumor extent, no distant metastases, and good constitution.

2. Palliative surgeryFor advanced patients with a wide range of tumors who have metastasis and cannot undergo first-class surgery, in order to alleviate pain, maintain nutrition and prolong life, only part of the tumor can be removed or some symptoms can be reduced'Surgery, such as a fistula, etc.

Symptoms of advanced malignancy

Patients with advanced malignant tumors, in addition to the aggravation of the symptoms of the tumor itself, are mainly accompanied by the following symptoms:

1. Fever

There are many of them, such as bacterial and viral infections, connective tissue diseases, and functional fever.

2. Pain

When normal tissues are destroyed and infiltrated by tumors, resulting in compression and destruction of adjacent nerve roots, local tissue ischemia and necrosis, obstruction of blood return, and infiltration of bone and periosteum, pain can be caused. Thus, pain is the most common concomitant symptom in patients with advanced malignancies.

3. Cachexia

It refers to the extreme emaciation, mental atrophy, and physical weakness of patients with advanced tumors.

Causes of extreme emaciation in patients with advanced malignant tumors

1. Cancer itself is a chronic wasting disease, due to the abnormal and rapid proliferation of cancer cells, resulting in tumor patients having higher nutritional needs than normal people, thus affecting the function of other organs in the body.

2. The toxic substances produced by cancer itself cause gastrointestinal disorders, such as nausea, vomiting, fever, decreased appetite, weight loss, and emaciation, which also affect the body's function.

3. Cancer compresses or invades adjacent important organs, thus affecting the physiological and anatomical functions of an individual's tissues and organs.

Tumors are divided into benign tumors, malignant tumors and borderline tumors, most of the benign tumors are in a quiescent state, grow slowly, do not cause damage to the surrounding normal tissues and organs, and are generally not ** after being removed, and are rarely life-threatening. Malignant tumors, on the other hand, have biological characteristics such as rapid growth, invasion and metastasis of other organs, which are still difficult to avoid and widely metastasized in the process, posing a serious threat to life. Borderline tumors fall somewhere in between.

According to the genesis of tumors, some are called cancer, and some are called tumors. For example, tumors that grow on the lining of solid organs are called cancer, such as stomach cancer, colorectal cancer, bladder cancer, etc., and tumors that grow on blood vessels, muscles, fat, and fibers are called tumors.

In this way, cancer is a tumor, a malignant tumor, and what is called a tumor is not necessarily cancer.

There are benign and malignant tumors, and malignant tumors are cancers.

It is okay to eat Wangyin mushrooms, he prevents tumors**, prevents cancer and fights cancer.

Wangyin mushroom can nourish the qi of the whole body's internal organs, regulate the body's metabolic function, strengthen the kidney and brain, clear heat and detoxify, reduce inflammation, reduce swelling and relieve pain, and is used for neurasthenia, impotence**, tracheal asthma, hot drenching pain, intestinal carbuncle edema, dissolving stasis and dispersing knots, boils and scrofula, and various cancers have a good effect. It has a good health care effect on tumor prevention and postoperative recovery.

According to the records of Ayurvedic Medicine, Wangyin mushroom can prevent cancer, inhibit the growth of cancer cells, reduce tumor growth, and reduce the possibility of mutation to cause cancer, and has a good effect on lung cancer, liver cancer, stomach cancer, pancreas, etc. It is commonly used in Indian men for impotence of kidney deficiency**, which can increase male duration and increase hardness. The incidence of Alzheimer's disease in India is much lower than in other countries, and it is also closely related to Wangyin.

The Chinese herbal medicine Wangyin mushroom contains polyphenols, quercetin, and selenium trace elements. The selenium and quercetin in Wangyin mushroom have anti-cancer, anti-cancer and anti-tumor effects, which can inhibit the proliferation of Xiang tissue, prevent cancer cell metastasis, and induce apoptosis of cancer cells. They often soaked the harvested Wangyin mushrooms in wine, soaked in water, and made soup.

The colloquial language of Indian people: stay away from diseases, stay away from tumors and cancers, and eat more mushrooms.

Early stage of cancer means that the cancer cells in the body are relatively limited and generally do not metastasize in a short period of time. On the contrary, in the case of advanced cancer, the cancer cells in the body have already metastasized locally or proximately at the time of discovery. This can also be seen as a boundary between early and advanced cancer.

Under normal circumstances, if the cancer is in the early stage, as long as it receives ** for a period of time, it is entirely possible for the cancer cells to be inhibited to a certain extent, and the lifespan will not be affected. But if it's in an advanced stage, it's hard to want it. As long as the re-examination is carried out on time, after the correct understanding of the occurrence and development of cancer, cancer patients and their families should be prepared for long-term combat, jointly cultivate an optimistic and correct attitude towards life, and establish a positive and victorious belief.

Cancer is at an advanced stage as soon as it is detected for two reasons.

One is determined by the characteristics of cancer. From cell mutation to the formation of cancer cells, to the proliferation and accumulation of cancer cells to form tumors, it is a long process of several years or more than ten years, during which the human body will not feel too obviously, that is, it is often said that there is a lack of specific symptoms in the early stage of cancer. Once a tumor is formed, its proliferation rate will accelerate geometrically, and it will progress very much in as little as a month or two, so it is already at an advanced stage when it is discovered.

The second is the difference in perception similar to survivor bias. If a person is diagnosed with cancer at an early stage, in time, and cured, people may not pay much attention. However, when a person is diagnosed with terminal cancer, dies not long after, or is miraculously cured, people will have a particularly strong impression.

Over time, what people retain in their memories is basically the concept that cancer is advanced as soon as it is discovered.

In China, lung cancer, gastric cancer, esophageal cancer, colorectal cancer and female breast cancer are in stage III and stage IV when they are diagnosed, that is, more than half of the patients are already in the advanced stage when they are diagnosed.

"When the cancer was discovered, it was already at an advanced stage, and there was not much time left. "Many cancer patients face this outcome when they are diagnosed. But in fact, the occurrence of cancer is never achieved overnight, but occurs imperceptibly in various carcinogenic factors.

Objectively speaking, cancer cells are also members of the cell and are harmless in themselves. When cancer cells first appear, the body doesn't react much. However, as the number of cancer cells increases, the body's nutrients begin to be over-consumed, normal tissues and structures are destroyed, and eventually cancer cells invade organs throughout the body and promote death.

So, that's why some cancer patients are diagnosed at an advanced stage. In fact, in the early stages, cancer can also show a lot of clues. If you can find it in time, you may be able to save the situation.

For example, fever, cough, abdominal pain, blood in the stool, loss of appetite, malaise, difficulty swallowing, unexplained weight loss, etc. Therefore, if there is an abnormality in the body, you must be vigilant and seek medical attention in time. Cancer cells are not stationary, and cancer patients will metastasize and spread when they reach an advanced stage.

Metastasis of cancer cells is the essential difference between early and advanced cancer, and it is also the cause of death in 90% of cancer patients. Cancer cell metastasis refers to the spread of cancer cells to other organs and tissues of the body through blood metastasis, lymphatic metastasis, micrometastasis and other pathways. After taking root, the cancer cells will continue to wreak havoc and develop into tumors.

What gives cancer cells the ability to metastasize is the weakening adhesion of cancer cells. Normal cells have a certain amount of adhesion between cells and do not run around. After the cancer cells mutate and lose their adhesion, they are like wild horses that have broken away, constantly dispersing and metastasizing in the body.

In the process of metastasis, although cancer cells will also go through many blockages, but their number is too large, there are always some fish that escape the pursuit of the immune system, and eventually metastasize to other organs and tissues, while constantly creating a suitable environment for their own survival. What's more, cancer cells can appear silently in body fluids or other tissues, and cannot be detected by CT or MRI.

Under the attack of powerful opponents, the normal cells in the body are constantly damaged, and the functions of tissues and organs are constantly destroyed, which not only brings great physical and mental pain to cancer patients, but also deprives patients of hope for survival.

Not all cancers are detected at an advanced stage, but it is true that some cancers are difficult to detect at an early stage. This is because in the early stages, cancer often has no obvious symptoms and does not cause pain or discomfort. As a result, it is difficult to detect cancer at an early stage, even with a routine physical examination.

In addition, some cancers may have symptoms similar to other diseases and can be easily misdiagnosed or missed. For example, early symptoms of lung cancer may be similar to a cold or bronchitis, and early symptoms of breast cancer may be similar to breast fibromas.

Therefore, for high-risk groups, if there is a family history of friends shirt or other risk factors, it is recommended to undergo regular physical examinations and screenings for early detection and**. For cancers that have already been diagnosed, early detection can improve the rate and survival.

The most effective screening method is: imaging examination + genetic testing Circulating tumor cell detection, which can detect the traces of tumors early.
