Cancer is a fatal disease which involves abnormal growth of cell usually derived from a single abnormal cell with the potential to invade or to spread in the other parts of the body. The cells of the body loss normal control mechanism and thus able to multiply continuously, invade nearby tissues, promote the growth of new blood vessels from which the cells derive the nutrients, and migrate to a distant part of the body. The cell of cancer can develop from any tissue within the body.
As the cancer cell grows, they form a mass of cancerous tissue called a tumor which invades the normal adjacent tissues and destroys them. The cancer cell from the initial site can spread throughout the body.
The tumor cells show the six hallmarks of cancer. These properties are required to produce a malignant tumor. It includes:
- Growth of cell and division absent the proper signals
- Even continuous growth and division give contrary signals
- Abstinence of programmed cell death
- Infinite number of cell division
- Promoting blood vessels structure
- Invasion of tissue and formation of metastases
Cancer rehabilitation is a program that helps people to maintain and restore physical and emotional well-being, make the mind positive, relaxed, and motivated to combat the disease in the best possible way. This programs is available for an individual who is recently diagnosed with cancer, an individual who is already suffering and undergoing treatment, and the third who has taken all the treatments and therapies and might be free from being a victim of cancer as well.
