Depending on the type of cancer it can either cause rapid cell growth or in some cases cause the cell to grow and divide at a slower rate. Also, depending on the type of cancer, some result in visible growth called tumor while others, such as leukemia, do not.
A cell has a life span, after which it receives instructions to die so that there is a regrowth of a stronger and healthier one. This is a natural and beneficial phenomenon called apoptosis. Cancerous cells lack this ability. As a result, they build up in the body, using oxygen and nutrients that would usually nourish other cells. Cancerous cells can form tumors, impair the immune system and cause other changes that prevent the body from functioning regularly.
Cancer gradually becomes more severe when cancerous cells begin to spread via the lymph nodes. These are clusters of immune cells located throughout the body. The easiest way to overcome cancer is to discover it at its early stage.
