Types of Neoplasms: Benign, Malignant, or Precancerous?

What is a Neoplasm?

It should be explained that neoplastic cells have a mode of development and multiplication that differentiates them from other cells in the affected area of the body. In a disordered way, they create a new element that is useless or harmful to the organism. Many neoplasms are harmless and therefore have no pathological significance. But it is very important to be able to recognize and identify them in time, in order to intervene early if they are actually risky tumor formations.

Benign Neoplasms

Definition of Benign Neoplasm

A benign neoplasm is a non-conforming proliferation of cells, but it is localized and therefore does not endanger overall health. Moles, lipomas, and uterine fibroids are some examples of benign neoplasms. Although these formations are not always dangerous, they can cause imbalances or dysfunctions if they reach a considerable size. Their development can exert pressure on glands, nerves, and neighboring structures, thus causing damage. This is why it is often recommended to remove them. Furthermore, it's important to note that benign neoplasms carry a potential risk of degeneration into a malignant tumor. The main characteristic of benign neoplastic cells is their abnormal proliferation.

The Most Common Benign Neoplastic Formations

Adenomas

Angiomas, also called hemangiomas, are vascular anomalies that develop both on the skin and inside the body, notably in the liver. Although not dangerous, they can cause bleeding or affect the proper functioning of surrounding organs when large and deeply rooted. In the case of a hemangioma covering half the face and causing vision or breathing problems, appropriate treatment must be undertaken.

Hemangiomas

Angiomas, or hemangiomas, are abnormal proliferations of blood vessels that form both on the skin and in internal organs such as the liver. They are not dangerous, but when large and deeply rooted, they can bleed or interfere with the functioning of neighboring organs. A hemangioma covering half the face and creating vision or breathing problems will need to be reduced by appropriate treatment.

Lipomas

A lipoma is a kind of ball of fat, which can form anywhere and can also grow quite large. In this case, it is usually removed.

Fibromas

Uterine fibroids are very common, although this abnormal proliferation of fibrous tissue can occur anywhere in the body. Of considerable size, they must be systematically removed, especially when located in the uterus, as they can affect female fertility and cause damage to the internal walls of the organ.

Papillomas

These are the classic skin "growths," such as warts, which are proliferations of epithelial tissue with a vascularized part. They can also form in internal organs, such as the bladder.

Precancerous Neoplasms

Definition of Precancerous Neoplasm

Precancerous lesions, also called neoplasms, represent a warning sign because they can develop into malignant tumors. It is therefore essential to manage and eliminate them if possible. In addition, some benign neoplasms, such as polyps and bladder papillomas, are considered at risk because they have a low but existing risk of turning into cancer. We have duly noted the dangers.

Different Types of Precancerous Neoplasms

Hyperplasia

A condition such as endometrial hyperplasia can lead to potentially dangerous consequences. Indeed, this condition often results from excessive hormonal stimulation and can develop into adenocarcinoma, a malignant tumor.

Atypias

This classification makes it possible to detect cells that are growing "unusually," that is to say abnormally. These atypical growths normally appear following inflammatory processes, but can also give rise to malignant neoplastic formations.

Metaplasia

Cells appear (under a microscope) as different from those of the tissue to which they belong. Metaplastic cells then transform into something other than their nature, and this process can be permanent or reversible. A non-dangerous example is scar tissue. In some cases, however, metaplasia can lead to the development of a malignant tumor.

Dysplasia

This is the most common precancerous lesion because the cells appear both abnormal in nature and chaotic in their proliferation. This uncontrolled proliferative process is the one that most often leads to the development of a malignant tumor.

Malignant Neoplasms

Regarding malignant neoplasms, here is a precise identikit based on their characteristics:

• It is an abnormal and uncontrolled growth of cells (compared to the tissue in which they form);
• They have the ability to invade other adjacent tissues and organs;
• They can reappear even after surgical removal in the same operated areas;
• They have the ability to spread to other organs by "migrating" in the bloodstream or lymphatic pathways and creating distant metastases;

Here are the most common types of cancer:

• Tumors originating from soft tissues, mucous membranes, or internal organs;
• Leukemias: Leukemias, blood tumors originating from the bone marrow;
• Lymphomas: Tumors manifest in the lymph glands (or lymph nodes) and lymphatic pathways that are part of the body's immune system.
• Sarcomas: Connective tissue of bones, muscles, cartilage, and blood vessels plays a crucial role in their development.
• Central Nervous System Tumors: These cells originate from the spinal cord or neurons of the brain;
