Cancer is composite of more than 200 diseases that form tumors in organs, stops responding to the signals and uncontrollable growth or abnormal functioning of cells.  Generally the old cells die and new cells grow, but in this case new cells keeps growing abnormally as the old cells remains. Cancer is not a sudden issue or event, it is an act that happens from over a period of time, may be months or years. Cancers are a curable disease when it is identified at the starting stage, after which it becomes very difficult or takes a tough process to cure it. The duration depends on the kind of cancer and how fast it affected the internal organs.

There are around 100 kinds of cancer that alters the cell structure causing tumours in body organs.  These tumours can grow and interrupt the nervous, digestive, and circulatory systems. It releases hormone that changes the normal function of the body. These tumors occur when:

  • A cell affected by cancer moves all through the body via blood and destroy the tissues that are well functioning.
  • The cell divides itself into number of cells making new blood vessels and the process is called angiogenesis.


When this tumour spreads to other parts it is said to have metastasis which is a very serious condition and thereby becomes difficult to be treated. Cancer is the second most caused disease in the US and the World Health Organisation (WHO) estimates that there are 14 million new cancer cases and 8.2 million deaths due to cancer in the year 2012. Cancer is considered to br the leading cause of mortality and morbidity worldwide. According to another examination by WHO, the new cases of cancer is expected to grow by 70 percentage in the next 20 years.

It is examined that cancer risks are reduced when tobacco, alcohol consumption is lowered or when limiting Uv rays exposure from the sun.
