Tumors are those clusters of masses made of abnormal and inappropriate tissue located in a specific region, this is the product of poor mitotic cell division where the main fault lies in the fact that cells rapidly replicate uncontrollably without first complying with the process of apoptosis (programmed cell death), according to this each layer of cell generated will pile up on the previous one giving a progressive growth of this abnormal mass of the organism.
Tumors can be cancerous or non-cancerous, which is commonly known as malignant and benign respectively; the difference between the two lies in their shape and blood supply: when tumors are irregular in shape with differently shaped edges and are covered by numerous large-caliber blood vessels, then it is said to be malignant; When said tumor has a totally perfect spherical appearance without any perceptible irregularity and is irrigated by few blood vessels with a small diameter, it is classified as benign.
As mentioned previously, tumors are the product of a poor mitotic division that results in an excessive accumulation of cells in the body; When the balance between dividing cells and dead cells is then disturbed, it is the main cause for developing tumors. The immune system plays a fundamental role in this pathology, since those who are immunosuppressed will have less control in terms of cell development, which hinders the patient's condition, progressively leading to certain death.
