GROWTH OF CANCER CELLS

Head & Neck — Wed, 21 Jan 2026 15:53:24 +0000

A tumor grows when normal cells develop genetic mutations that disrupt their normal growth signals, causing them to divide uncontrollably, ignore programmed cell death, and accumulate into a mass, forming either non-cancerous (benign) or cancerous (malignant) growths that can invade tissues and spread

TUMORS GROW

The cancer cells grow and divide to create more cells and will eventually form a tumour. A tumour may contain millions of cancer cells.

CANCER CELLS

Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of aging or damage. Healthy cells stop dividing when there is no longer a need for more daughter cells, but cancer cells continue to produce copies. They are also able to spread from one part of the body to another in a process known as metastasis.

There are different categories of cancer cell, defined according to the cell type from which they originate:

Carcinoma
Leukaemia
Lymphoma
Myeloma
Sarcoma
Mesothelioma

Cancer cells are created when the genes responsible for regulating cell division are damaged.

Damage to DNA can be caused by exposure to radiation, chemicals, and other environmental sources, but mutations also accumulate naturally over time through uncorrected errors in DNA transcription, making age another risk factor.

MACROPHAGE DEVOURS CANCER CELLS

MACROPHAGE DEVOURS CANCER CELLS

The word #macrophage comes from ancient greek and literally means “large eater”.

This definition perfectly captures the devouring nature of this cell, whose mission is to engulf and kill pathogens.

In addition, macrophages play a key role in #immunity, as they secrete a variety of modulator substances and are professional antigen-presenting cells.

In the initial stages of tumor formation, most of macrophages are type M1, which promote the anti-tumor immune response.

Macrophages phagocytize the apoptotic bodies and other cellular debris of tumor cells, internalizing tumor antigens, which are after processed and presented to cytototoxic cells. They also secrete #cytokines, which are key proteins in the inflammatory response.
