Basics of Cancer

Cancer development is fairly well researched and can be identified by those in the medical community. Cells that develop incorrectly cause Cancer. All cancers start from bad cell growth, no matter where it is located within the body. Normal cells divide and grow in the body on a regular, healthy basis everyday. The most cell division and growth occurs when a person is first born and through to adulthood, then it begins to slow down and usually only occurs when old cells die or need repaired due to injury.

Cancer cells, on the other hand, do not die off as quickly and divide more rapidly. They then mass together to form a tumor or travel to other areas of the body and begin taking the place of normal cells, which is called metastasis. This is why most cancers are a tumor. Cancers are named for the part of the body in which they originate. This fact is important later during treatment of the cancer. Cancer cells are in the body because of DNA damage. DNA damage is not uncommon, but most of the time the DNA repairs itself and cancer does not result. DNA damage can happen due to a couple of factors. It can be inherited or it can occur from environmental factors.

Cancer cells react differently in different parts of the body. That is why cancer treatment is based upon where the cancer starts even if it travels elsewhere in the body. Depending on the part of the body where it originates, cancer cells will grow at various rates and respond to some treatments better than others. One mystery about cancer is why some parts of the body are more susceptible to cancer than others. The answer seems to lie with the amount of cell division within each area of the body. Areas of the body that have more cell division seems to be more likely to develop cancer than areas of the body where cell division is slow.

When trying to lower your risk of developing cancer there are many things you can do based upon what research has shown about cancer. By using these findings, you can adjust your lifestyle and diet to avoid things that raise your risk for developing cancer. There is no foolproof way to avoid cancer, though. Not everything is known about cancer, so being able to avoid it all together is virtually impossible. Lowering your risks, however, is much better than not doing anything at all. Research has shown that the less risk factor you have, the less of a chance you have for developing cancer.
