Chronic Disease Cancer

The body part or cell where abnormal growth begins is called as Cancer. Cancer is a group of more then 100 diseases that begin when abnormal cells in the body grow out of control. Normally, cells grow and divide to create new cells as they are needed to keep the body healthy. Sometimes this does not work properly and cancer forms. Most cancers are named ... For example, cancer in the breast is called breast cancer. 

Cancer is a very common disease now a days. General risk factors for cancer include; older age, a personal family history of cancer, using tobacco, some types of viral infections (such as HPV), specific chemicals and exposure to radiation (including ultra violet radiation). Although risk-factors like using tobacco, being over weight, and getting sunburns can be avoided. Other risk-factors cannot be controlled or avoided such as getting old. A risk-factor is anything that increases a person’s likelihood of developing cancer, although risk-factors often influence the development of cancer. Some people with several risk-factors never develop cancer, while others with no non risk-factors do. Knowing your risk-factors, discussing them with your doctor and having a detailed family history taking by your doctor may help you make more informed lifestyle choices. In general terms, risk is the probabilities that an event will happen. When talking about cancer, risk is most often used to describe the chance that a person will develop cancer. Knowing this information not only helps you make more informed decisions about your health, but it also helps researchers and oncologists improve the health of large numbers of people. For example, discovering that people who smoke have a higher risk of lung cancer then people who don’t smoke jump started a world wide campaign to encourage people to quit smoking or to not begin to smoke. Absolute Risk is the chance that a person will develop a disease during a given period of time. This is helpful for determining how many people are at risk. For example, the statement one out of eight women (12.5%) will develop breast cancer describes the absolute risk for the general population of women. This number only relates to the general population. Women older then 70 have a higher risk of breast cancer then younger women because breast cancer risk increases with age. Risk-factors that a person can control are called modifiable risk-factors. Many other factors in our environment, diet, and lifestyle may cause or prevent cancer. Not smoking or quitting smoking lowers the risk of getting cancer. It is believed that cigarette smoking causes about 30% of all cancer deaths in the United States. People who are physically active have a lower risk of certain cancers than those who are not. The food that you eat on a regular basis makes up your diet. It is hard to study the effects of diet on cancer because a person’s diet includes foods that may protect against cancer and foods that may increase the risk of cancer. Physical activity, diet, and abstance from cigarette smoking are all a good way of prevention from cancer.
