Cancer can originate from any part of the body and is named after the organ that is affected.

Cancer

ycyrf.net At the basic level, our bodies are made up of living cells. These cells grow by dividing and multiplying, thus allowing our bodies to grow and mature as well. The division and multiplication of cells follow a pattern and each cell eventually mature and die. With cancer, the growth of cells takes on an abnormal pattern.
What happens is that the abnormal cells continue growing without end. As a result, a mass (or growth) is formed. These masses are also called tumors.
Not all tumors are cancers. Tumors may be benign or malignant. Benign tumors do not spread to other parts of the body and are not considered cancerous. On the other hand, malignant tumors can spread to other parts of the body. They do so by invading organ cells which are in close proximity. Another mechanism by which cancer cells spread is by entering the bloodstream and reaching organs far from the originally affected one. This is called the process of metastasis.
Cancer does not choose its victims. It can affect any person, regardless of age, gender, or race. Cancer can originate from any part of the body and is named after the organ that is affected. Even when it has metastasized, the cancer is still named from the originating organ. For example, if the cancer started in the lungs and spread to the bones and stomach, it is still labeled as lung cancer.
There are countless different types of cancer and each one may have its own set of symptoms and manifestations. However, there are some general effects of cancer. Some of these are chronic fatigue, unexplained weight loss, fever, skin abnormalities, and pain.
