What is carcinoma in situ What is carcinoma in situ

Generally speaking, the malignant tumor of the epithelium is confined to the ** or mucosa, and has not yet invaded the dermal tissue through the basement membrane under the ** or the mucosa, let alone infiltrated and distant metastasis.

It is more common in the elderly, and it is more common at the corneal conjunctival junction, and the tumor has a clear boundary with adjacent normal tissues. It develops slowly, can be confined to the epithelium for several years, and pathological examination shows an irregular epidermal hyperplasia, which is a true intraepithelial carcinoma.

Carcinoma in situ is stage 0 cancer, which is the earliest stage of cancer, and the reason why cancer is terrible is that it will metastasize, and it is difficult to completely control it after metastasis, while carcinoma in situ does not have the characteristic of metastasis. Therefore, if it is found in the carcinoma in situ stage, it is a mild disease, and the plan is relatively simple, usually it is directly resected, and there is no need to do chemotherapy, which is completely possible.

If the doctor recommends surgery**, I recommend that the patient be able to have surgery as soon as possible**. Topical antibiotics and corticosteroid ophthalmic agents are the main treatments, supplemented by nutrition and support, and cyclosporine A can be applied locally or systemically if necessary. In the prognosis of the patient, the patient should pay more attention to the nutrition of the food in the diet, the food must be hygienic, and then the patient should pay more attention to rest, do not worry about their condition mentally, take it easy, your worries about the condition are harmful to you, and then the patient should return to the hospital regularly for reexamination.

Carcinoma in situ is not without the possibility of **, in the prognosis of the patient in order to control its **, in addition to regular re-examination, I recommend that the patient can do the anti-vascular ** tumor for a long time in the prognosis, RG3 in traditional Chinese medicine ginseng has been certified by phase IV clinical trial, proving that it has the effect of inhibiting the growth of tumor neovascularization, and it is suitable for patients to take it for a long time because it is a monomer Chinese medicine ingredient. Combined with traditional Chinese medicine**, the chance of carcinoma in situ** can be higher.

Carcinoma in situ is the first, first, and first cancer detected by the patient, and further development and change of carcinoma in situ may become metastatic cancer. In fact, in your question supplement: male... Female··· Two lines is the narrative of carcinoma in situ.

For example, someone first got stomach cancer and then esophageal cancer. Gastric cancer is carcinoma in situ and esophageal cancer is metastatic cancer.

Primary cancer is a cancer that occurs in normal tissues and organs under the action of various internal and external carcinogenic factors. In general, "primary" refers to the origin of the cancer. All organs and tissues except nails and hair can develop into primary cancer.

If cancer cells travel from the primary site to other parts of the body through the bloodstream and lymphatic vessels, it is called metastatic cancer. For example, hepatocellular carcinoma develops lung metastases, while the medical diagnosis is primary hepatocellular carcinoma and metastatic lung cancer. It should be said that primary cancer includes all stages of cancer development, namely carcinoma in situ, invasive carcinoma, systemic spread, and metastasis.

Primary cancers are only eligible for compensation at the carcinoma-in-situ stage.

Carcinoma in situ is the earliest stage of cancer, and the tumor capsule should be intact at the stage of carcinoma in situ, so it is easiest to completely remove the cancer cells in the patient's body through surgery as soon as possible.

In order to control it, patients can consider taking RG3 in traditional Chinese medicine ginsenosides for a long time in the prognosis stage to do anti-vascular.

The main effect of anti-vascular ** is that it acts on the microenvironment of tumor cells, and it has the effect of blocking the nutrients needed in the process of tumor growth and inducing apoptosis for the growth of tumor cells. In the early stage of tumor cell growth, it can reduce the microvascular density of tumor cells, and it is possible to convert tumor cells into normal cells. There is an anti-vascular adjuvant carcinoma in situ, and the probability of getting it is much higher.

Carcinoma in situ, also known as intraepithelial epithelial carcinoma, is still cancer in nature, although it does not invade and does not invade the basement membrane. Clinicopathologically defined carcinoma in situ, it is an atypical hyperplasia in the mucosal epithelial layer or ** epidermal layer involving the whole thickness of the epithelium, but has not yet broken through the basement membrane and grows downward invasion. However, from the perspective of the section of carcinoma in situ, the epithelial cells are polarized, and the normal epithelial cells are replaced by heterosexual or multinucleated singular cells, and the pathological appearance is all cancerous, so carcinoma in situ is also a type of cancer.

At present, in order not to misunderstand, many clinicopathologists will directly abandon the name of carcinoma in situ and judge by the degree of tumor differentiation of the organ lesion site, such as cervical cancer, which has not reached the basement membrane formation infiltration, and the cancer is generally not reported in medicine, and the clinical plan will be judged by the depth of the tumor lesion of the cervical cells.

Carcinoma in situ is common in the elderly, often at the corneal conjunctival junction, and the lesion is usually clearly demarcated from adjacent normal tissue. The pathological examination of carcinoma in situ generally shows irregular epidermal hyperplasia, which develops rapidly and mostly survives in the epithelium for many years. Common carcinoma in situ includes cervix, intraductal breast cancer, esophageal cancer, and ** cancer.

Epithelial tissue is the inner and outer surface tissue covering the surface of the body and organs, and most of the cancer cells of carcinoma in situ only survive in the epithelial layer and have not yet invaded, which is in contrast to the invasion or distant metastasis of general malignant tumors, so it will be called "stage 0 cancer" in medicine.

Carcinoma in situ progresses to early invasive cancer, but most carcinomas in situ are limited in their extent and can resolve or involve other large areas without invading the basement membrane. Because carcinoma in situ is a cancer that occurs before invasion and metastasis, when it is detected in the early stage, the probability is very high, for example, cervical cancer is diagnosed as carcinoma in situ in an early stage, this situation does not show obvious symptoms, and it needs to be detected by PET CT or cervical smear and other methods.

Pathological features of carcinoma in situ:

1.The tumour is located at the corneal conjunctival junction and has a pronounced bulge with a rough surface and many blood vessels.

2.Cancerous cells have a clear boundary with adjacent tissues.

3.The mass at the corneal conjunctival junction develops slowly and has not progressed to invasion of the basement membrane.

Carcinoma in situ is a type of cancer, which belongs to the earliest stage of cancer, and the general development sequence of cancer is as follows: 1. Precancerous lesions: It refers to a part of the lesions that are not cancerous in themselves, but have the potential to transform into pure laughing cancer.

In essence, it is a benign lesion. Management: prophylactic excision or close follow-up.

Precancerous lesions are not considered real cancer) 2. In situ Bucket Pants Carcinoma: It refers to the cancerous transformation confined to the local area and does not break through the epithelial basement membrane structure (specialized extracellular matrix at the bottom of the epithelium). It is cancerous in nature, but it does not grow into the surrounding tissues and is not destructive.

Because clinicians and ordinary people usually think that the condition is serious when they hear "cancer", it often leads to excessive **. In recent years, the concept has been to change the names of carcinoma in situ and partially invasive intramucosal cancer to "intraepithelial neoplasia" and "intramucosal neoplasia" to avoid the excessive nature of the name "cancer". Hazards:

Some, but not all, carcinoma in situ can be further transformed into invasive carcinoma. Management: local excision of the lesion (to ensure that the lesion can be completely removed).

Postoperative follow-up, but no further radiotherapy, chemotherapy, etc. are required. Carcinoma in situ has the best prognosis, if well controlled, carcinoma in situ has the best possibility, postoperative patients can consider eating ginseng RG3 as anti-vascular**, it is a traditional Chinese medicine that has an inhibitory effect on tumor growth and metastasis. Eating it for a long time can reduce the ** rate of carcinoma in situ.

What is carcinoma in situ? When many consumers buy critical illness insurance or cancer prevention insurance, many terms also indicate that carcinoma in situ will not be compensated, so many consumers do not understand why it is also cancer, but carcinoma in situ is not compensated.

What is carcinoma in situ?

Many people will understand carcinoma in situ as the cancer formed by the original normal cell lesion becoming malignant tumor cells, and it is in the stage without metastasis, but if you think so, it is very wrong, this is "carcinoma in situ" or "primary malignant tumor", primary carcinoma is normal cancer, belongs to the scope of claims, and carcinoma in situ are two completely different concepts.

Carcinoma in situ, also known as "intraepithelial carcinoma", refers to the malignant tumor of the epithelium confined to the ** or mucosa, and has not invaded the dermal tissue through ** or the basement membrane below the mucosa, let alone the state of invasion and distant metastasis, therefore, carcinoma in situ is sometimes called "pre-invasive cancer" or "stage 0 cancer", strictly speaking, it is not a real cancer at all.

The reason why cancer is terrible is because it will metastasize, and it is difficult to completely control it after metastasis, and carcinoma in situ does not have the characteristics of metastasis, so if it is found in the carcinoma in situ stage, it is a milder disease, and the plan is relatively simple, usually it is directly resected, no chemotherapy is required, it is completely possible, and the cost is relatively cheap, and usually medical insurance can directly cover it.

Therefore, carcinoma in situ does not meet the criteria of three highs and one low (high mortality, high incidence, high cost and low rate) of critical illness, so this is the reason why critical illness insurance does not cover carcinoma in situ.

Carcinoma in situ refers to carcinoma that is only seen in the cortex or epidermis and often affects the whole thickness of the epithelium, but the basement membrane is intact and there is no interstitial invasion. Carcinoma in situ is one of the earliest cancers, and if it continues to develop, it can become invasive cancer, but there are a few people who believe that muffled carcinoma in situ can maintain the structure of carcinoma in situ for a long time, and even regress. But in any case, it should be prevented from developing into invasive cancer, and the cultivation of the mask should be pin to increase the ** rate.
