To begin with, cancer is the disease resulting from abnormal cells uncontrollably dividing themselves until they are capable of jointly and fatally attacking neighboring body cells.
Cancerous cells easily travel to different parts of the body through the bloodstream and the lymph fluid circulation systems.
For starters, cancer is the collective term referring to very many diseases that all exhibit similar symptoms while developing.
It is when they infect distinct body organs that the cancer causes exhibit slightly distinct symptoms.
A good example is when cancer conditions start in a person's colon, always at the base of natural skin cells.
Though a cancer, this is specifically called skin cell carcinoma.
That means that cancer conditions essentially have similarities among which, are the potential causes.
This article briefly lists the possible cancer causes.
Remember that cancer is always caused by particular agents and substances used in the lifetime of a person, ironically, most of these can be done away with.
Various types of cancer have been medically linked to the genetic make up of a person.
A good example is leukemia.
Leukemia, a term referring to cancer resulting from abnormally increased blood cells production until they surpasses by far the natural body requirements, occurs in newborn children who have not abused any cancer causing substances but as a result of genetic predisposition.
Female's radical hormonal change, mostly after repetitively using contraceptive pills, has also been linked to cancer causes of breast and cervical types.
The ultraviolet rays projected from the sun have also been attributed to causing skin cancer.
Sarcoma cancer causes usually starts from human bones, body fat, blood vessels and other key connective tissues.
Blood-forming tissues are mainly located in the bone marrow and incidentary leukemia starts here, causing lethal malfunction in the whole body.
Lymphoma is also a type of cancer which causes the immune system of a patient to overly produce blood cells until they invade normal body cells causing a fatal type of cancer.
The cancer causes affecting the human nervous system are now a very common condition.
They are known to affect the human brain and also the entire human spinal cord.
The cell is the most basic functional unit among all living things and for us to clearly understand cancer causes, it is very important to know how ordinary body cells function and thus know what eventually makes them to turn cancerous.
Humans are made up of cells and cells combine to form tissues, while tissues combine to form various body organs.
The organs combine in function to form the wholesome human body.
Cells grow and frequently die to be replaced by newly formed cells.
This is an orderly natural process which does sometimes go wrong, if the DNA chemical which is responsible for an orderly growth process gets impaired or even damaged.
These conditions results to cell mutants and actually, some cells die prematurely before new ones are formed, or so many of replacement cells are abnormally formed.
These additional cells eventually forms the lumps called tumors.
Although some tumors can be removal by surgical operations, malignant cancer causes of cancerous tumors invade organs' tissue cells and recur even after surgical removal.
