Carcinoma in situ is cancer that has started but has not yet spread to nearby tissue.
Nowadays and with medical advancements More and more cancers That was found at a stage called cancer in situ. It is not known whether carcinoma in situ will progress to cancer. But for the most part The risk of cancer spreading comes from cancer in situ.
Carcinoma in situ is also called stage 0 cancer and is non-invasive, while all other stages from stage 1 to stage 4 are considered invasive. Is carcinoma in situ the same as cancer cells? What types of cancer can be cancer in situ? And how is it different from cancer that spreads?
cancer in situ
Carcinoma in situ is cancer that has started but has not yet spread to nearby tissue. It is the earliest stage of cancer and hence is considered non-invasive as it is a type 0 cancer. When the cancer enters stage 1 and reaches stage 4 it is considered to be invasive because in these cases the cancer has spread to. nearby tissue It is important to note that not all cancers will be stage 0 or cancer in situ.
Diagnosis of cancer in situ can be done under a microscope by a certified specialist. It is known to be cancerous when there are cancer cells.
cancer in situ How is it different from cancer that spreads?
Carcinoma in situ does not invade the basement membrane. Therefore, there is no stromal invasion. Even though the cells looked like aggressive cancer cells, but not yet invaded “Cancer” can be equated with the word “cancer” because 85% of cancers are cancers. Subtypes of cancer include adenocarcinoma. squamous cell carcinoma transitional cell carcinoma (in the bladder or kidney) and basal cell carcinoma Carcinoma in situ can be further defined by the type of tissue from which the cancer began.
Tumors such as sarcomas occur in tissue that lacks a basement membrane. Therefore, for this type of cancer, there is no cancer in the situ stage. In other words, tumors such as osteosarcoma (bone cancer) do not have a pre-metastatic stage. (There is no cancer in the in situ stage) and the cells are considered normal or cancerous. In the same way Blood-related cancers such as leukemia and lymphoma There is no progression before spreading. But it is a cancer stage that people can be screened for. For cancers that do not have cancer in situ, screening tests (such as Pap smears) are not effective in detecting them early. Because when abnormal cells are detected Cells are considered to be aggressive and have the potential to spread. (Diffusion) .
Cancer in situ is usually removed by surgery. Although the type of surgery depends on the location. And even within a particular place there are important arguments.
These decisions are based on local abnormalities. Risk factors that determine whether a cancer in situ is likely to develop into an invasive cancer are a person’s age and other factors. that the doctor must consider There are people who, if they have an abnormality but it’s not cancer, I don’t mind keeping it in my body. Although some people prefer to get rid of things that may pose a cancer risk.
Other treatments It may also be used for cancer in situ in other areas. of the body as wellFor example, some early-stage skin cancers can be treated with topical chemotherapy or other treatments.
If you have been diagnosed with cancer in situ You may be very afraid of what will happen next.Even though stage 0 cancer isn’t always a cause for concern, But the problem is when it becomes metastatic cancer. Whatever it is Your doctor will tell you how you need to treat this disorder as soon as possible.
