Do I Have Cancer?

Cancer is the leading cause of death worldwide. According to estimates by the International Agency for Research on Cancer (IARC), 12.7 million people were diagnosed and 7.6 million died of the disease in 2008. One in eight deaths worldwide is due to this condition. It causes more deaths than AIDS, tuberculosis and malaria combined. Cancer deaths worldwide is expected to continue rising to more than $ 11 million in 2030.

These figures are alarming. The task for medical professionals and health is ever going to increase if the number of cases increases in such proportions. Given the fact that the risk of contracting this disease increases with age and elderly population is increasing and that obesity increases the risk of cancer and obesity is increasing, unless there is a great advances in technology to detect and treat early, will be the greatest burden of the health of every community and country around the world for many years to come. The management of this condition is a challenge not only to medical and health professionals, but all members of a community around the world. The health system already struggling to handle the multitude of chronic and acute diseases of modern society is stretched to the limit as consistent with the rise in the number of cancer cases.

Having worked in family practice doctor for many years, I feel passionately about people who suffer from this deadly condition and the consequences of their diagnosis and treatment on physical health, emotional and spiritual health of patients. This is very interesting, especially if it was a one preventable, such as lung or cervix.

As a physician, I take it as a personal responsibility and a challenge to do my bit to educate people about cancer and means of prevention, if any. I will start doing so many articles written in here regularly for a period of time. I hope people take advantage of information from my articles.

How is cancer?

A cell is the smallest structural and functional unit of our body. Normally, cells grow and divide to form new cells. When these cells become old or damaged, they die and are replaced by new cells. This process is controlled by genes. But sometimes this orderly process does not occur. Old and damaged cells do not die and new cells keep dividing even when the body does not need. As a result, a mass of tissue called a tumor or lump forms in our body.

The tumor or lump may be benign or malignant. Benign tumors are not cancer while malignant tumors are formed by cancer cells. Therefore, malignant tumors and cancer mean the same thing. The ability of the cell to grow out of control and invade other tissues makes a cell a cancer cell. In most cases, these abnormal cells form a tumor, but in other cases such as leukemia can not be any tumor.

Benign tumors usually grow slowly and do not spread to other parts of the body while the malignant tumors grow faster and invade adjoining parts of the body and spread to other organs.;u=51451;u=15886;u=115278
