The Different Types of Cancer
Cancer simply defined is the abnormal growth of cells in some part of the body. It may occur in the brain, the lungs or even the breasts. This article will cover 2 different types of cancers and their causes. causes of cancer may be different depending on the type. However, one factor, heredity, results in both cancers.
It is difficult to ascertain the real causes of cancer. Still, heredity is cited as the principal cause. Family history places one at a high risk of developing cancer. Such cancers as brain and ovarian are often associated with hereditary factors. Cancer may also result in people who may have at one time or another suffered from the diseases. This makes prior history another cause of the diseases. Nonetheless, there are other factors that often linked to external environment that cause diverse types of cancer.
Smoking and air pollution are also said to cause cancer. Other factors that are said to cause cancer are radiation and even sunlight. Still, there are many forms of cancer. One of the most common cancers in the United States is lung cancer which is caused by smoking. In the US, 90% of the reported cases of lung cancer are as a result from cigarette smoking. This is especially true for active smokers. Still, passive smokers have a 24% chance of developing lung cancer. On the other hand, about 1% of lung cancers are as a result of air pollution. Consequently, the causes of lung cancer may lie in exposure to pollution from industries, power plants and commonly vehicles.
A victim’s personal situation can be linked to the development of certain cancers. Case in point, cancer in women is likely to be caused by hormones. According to reports, early menstruation and late menopauses in women is likely to result in breast cancer. Concomitantly, the use of hormone replacement therapy by post menopausal women exposes them to the risk of developing breast cancer. While there is no evidence in support of this, birth control pills are also said to be probable causes of breast cancer.
Causes of cancer are two pronged. These are prior history with the disease and heredity. Different forms of cancer have distinct causes. Hormones, use of hormone replacement therapy and the use of birth control pills are factors associated with the development of breast cancer. On the other hand, smoking and air pollution are said to be the likely lung cancer causes.
