Learn More About Carcinoma
Carcinoma is a malignant form of cancer. The carcinoma after it occurs spreads to surrounding tissues and organs. Carcinoma occurs in epithelial cells. The epithelium is a tissue that made up of cells that line the cavities and surface of structures that are spread in the body.
Metastasis is the spread of a disease of one organ or part of organ to another organ or part of organ. The cells that make this up are called epithelial cells. The epithelium lines the inside cavities and the outside of the body. There are epithelial cells that line the inside of the mouth, the esophagus, and other parts of the body. Carcinomas may spread to issue and organs, and lymph nodes and other sites in the body.
The histopathological appearance of carcinomas determines the way it is classified.
Types of Carcinoma
Adenocarcinoma and Squampous Cell Carcinoma are the two common types of carcinoma. They are like tumors and they have glandular and squamous cell appearance. Carcinoma may become malignant and cause a lot of pain. There are many anaplastic tumors that do not have a certain histological appearance and these are known as undifferentiated carcinoma. Many carcinomas may become malignant and show the related symptoms. Carcinomas occur in lung very often and there are different types of these carcinomas.
There are adenocarcinomas that occur in the epithelial cells of glandular tissues. These make up 30 to 40 % of all lung carcinomas. The squamous cell carcinoma are caused due to squamous metaplasia.
These a re 20- 30% of all lung tumors. The small cell carcinoma is mainly caused due to smoking. These carcinomas metastasize early. The large cell undifferentiated carcinomas make up 10 to 15% of lung tumors.
There are tumors that are so undifferentiated that they do not have a particular histopathological appearance. As they are undifferentiated, they are different to identify. These carcinomas are aggressive. The extent of spread of the cancer and its determination refers to staging. The degree of differentiation from the parent tissue refers to grading. The treatments include surgical resection, radiation therapy, and chemotherapy. The staging is done to ascertain how much the carcinoma has grown before it has been diagnosed. The process of staging is often extremely important to determine the treatment that is offered to a person.
What Happens When Someone Has Carcinoma?
The carcinomas spread and disrupt the functioning of normal organs. There are malignant properties of carcinomas that that set them apart from benign tumors. The carcinomas are caused by the abnormalities of the genetic material of the cells. Carcinomas may affect the people of any age even fetuses. The squamous cell carcinomas may occur in different organs like the prostate, lungs, bladder, vagina, cervix, esophagus, urinary bladder, skin, lips, mouth, etc. The basal cell carcinoma is a type of non-melanoma skin cancer that most commonly occurs in the United States. The majority of these cancers occur in those areas of the skin that are exposed to sunlight or other ultraviolet radiation.
