Leading Cause of Cancer Death

How cancer causes death is a crucial question and is satisfactorily answered by oncologists, researches as well as medical experts. They give results with previous researches, available content, past and current status of the disease to produce accurate findings.

Unnecessary inference with organ functioning
Any vital body organ when begins to malfunction, can bring serious health disorders. In extreme cases it can deprive the person of that organ permanently or cause death. What tumors do is, they hamper proper working of the part they develop in, leading to many complications.

Despite treatment, if there is no improvement and the interfering problem persists for a prolonged period of time, the organ completely stops working and neighboring body areas are damaged as well, especially in metastatic type.

Thus the affected person is no longer capable enough to survive, so he dies eventually. This is true of liver and pancreatic primary tumors that often block the bile ducts which consequently have toxic effect in the individual who finally is deprived of his precious life. Same is the case in lung cancer that does not allow alveoli to contract and expand properly to exchange air. The respiratory system thus badly influenced by the presence of tumor, is unable to supply ample oxygen to the body, so death occurs as a result.

Reduced blood supply
In many cases, cancer cells either decrease or totally stop the supply of the blood to other body organs. They do it by forming a network of blood vessels all around the tumor to feed it. This phenomenon is named as Angiogenesis in medical terminology. Nutrients and oxygen provision is made possible to all body organs via these vessels and waste is also disposed off.

Disturbed hormonal production
While cancer cells affect the organs, there is a sever malfunctioning and the hormones produced are either scanty according to the requirement or not secreted at all. An imbalanced homeostasis thus caused many disturbances in the patient.

Paraneoplastic syndromes
This syndrome affects almost all body organs and tissues in affected person as is a result of cancer. The onset and level of severity varies a great deal from one patient to another, but it surely stays there to bring about a big damage to the individual, sometime totally incurable by any expert or therapist, so the person had to leave this world for good. People with tumor have these disorders:
  • Anemia (sever iron deficiency)
  • Hypoglycemia (an abnormally low level of glucose)
  • Hypoalbuminemia(abnormally low level of albumin in the blood)
  • Hyponatrmia(low level of sodium in the blood)
  • Hypercalcemia(a higher-than-normal level of calcium)
  • Elevated level of ESR(Electron spin resonance)
  • Anorexia(loss of appetite)
  • Retinopathy(disease of retina, the back of the eye)
  • Neuropathy (disease of peripheral nerves of central nervous system)
  • Cachexia (lack of strength and vitality of body and mind)
  • Vascular system changes
  • Endocrine(hormonal) problems
  • Neuromuscular abnormalities
  • Bones are affected
  • Weight loss
  • Perverted immune reaction to antigens
  • Autoimmune disease
  • Genetic problems
How come a person survive with too many complicated problems occurred solely or simultaneously. When cancer cells metastasize, their killing property is drastically increased with very low survival chances of the patient.

Mutagenesis- a trigger for death causing factors
Persons born with mutation in genes are likely to get cancer more than those born with normal make up. Genetic defects further worsen the condition by helping cancer cells to leave their detrimental effects in the body thus trigger the death program. Many clinical reports have confirmed that a person with such mutation carries this gene throughout his life whereas these carry on growing in number at various stages of transformation.
