What is carcinoma?

To understand what a carcinoma is, you need to have an idea of ​​what cancer is. Cancer is a collective name for a group of diseases characterized by abnormal growth and cell division, which, in turn, leads to the formation of tumors in the body. Such uncontrolled cell division can begin in blood vessels, in the brain, in the spinal cord, in the bones, in the cells of the immune system, etc.

Carcinoma is a type of cancer that develops from the epithelial cells of the tissues of organs such as the liver and kidneys.

Types of carcinoma

Although carcinoma can develop in different parts of the body, it is customary to talk about the following types of it:

  • Basal cell carcinoma;
  • Squamous carcinoma;
  • Renal cell carcinoma;
  • Ductal carcinoma in situ (in situ means that we are talking about a malignant tumor at the initial stages of development);
  • Infiltrative ductal carcinoma.

Basal cell carcinoma is the most common type of carcinoma that forms in the lower (basal) skin layer.This type of cancer rarely spreads further to other organs of the body. It is necessary to get medical help as soon as possible in order to get rid of this disease as soon as possible and to remain without scars on the skin.

Basal cell carcinoma looks like:

  • open wound;
  • red spot;
  • pink growth;
  • shiny and translucent bump or knot.

Causes of carcinoma

If you are ill with basal cell or squamous cell carcinoma, it is likely that this happened due to frequent exposure to the sun.

Renal cell carcinoma is formed due to smoking, poor lifestyle choices and due to poor heredity.

In situ ductal carcinoma and infiltrative ductal carcinoma (or breast cancer) develop under the influence of hormonal and genetic factors, and they are also associated with late pregnancy or with age-related changes in a woman's body.


Depending on the location and size of the tumor, they are treated with carcinoma by radiotherapy, surgically or with chemotherapy.
