Is carcinoma in situ cancer and what is carcinoma in situ?

Carcinoma in situ is commonly affected by the elderly, and the progression of carcinoma in situ is relatively slow. Carcinoma in situ is the early detection of cancer, also known as "stage 0 cancer", and its ** chance is almost 100%. The 5 stages of tumorigenesis and development are a process of slow and gradual progression, mainly including:

Precancerous lesions-carcinoma in situ - distant metastasis from early invasive cancer to later stages, carcinoma in situ is a malignant tumor, but it does not break through the basement membrane and can be recovered in time.

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.

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 truly modified intraepithelial carcinoma.

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.
