What is Cancer?

Cancer is the abnormal growth of cells. Cancers arise from an organ or body structure and are composed of tiny cells that have lost the ability to stop growing. This growing mass of cells then projects from that organ or body structure until it becomes large enough to be noticed by a patient or physician. Occasionally, cancer may be detected " incidentally' by a laboratory test or x-ray that is, the test or x-ray may have been ordered for purpose of routine screening or for an entirely different reason; in such a case, the cancer gets notices almost by accident. At this point it may be referred to as a " mass"," growth", " tumor", " nodule", " spot", "lump", "lesion" or malignancy."

In general, the Cancer must reach a size of 1 centimeter, or be made up of 1 million cells, before it is detected. Exceptions to this general rule include Cancer of the blood and bone marrow- called Lymphomas, Leukemias and Multiple Myeloma - which frequently do not produce a mass but will be evident on laboratory tests: these cancers still require more than a million cells to be present before they are detected.

  9. This post was a refresher for me. My wife has had 3 bouts with breast cancer so we are very familiar with all the signs and most of the terms. Thanks for this post for those who are not afflicted with this dreadful disease. I'm sure it has enlightened them about cancer and what to look for when trying to detect it.
