Colon Cancer Life Expectancy and Survival Rate
Colon cancer life expectancy gives an idea about the survival rate of a victim and gives information about the possibility of an extent to which the cancer tumors can be cured or curbed in a particular stage. It is an important concept as the reliability and efficiency of the current methods to cure colon cancer can be judged by having a look over the survival rate.
Colon cancer life expectancy meaning
Understanding colon cancer survival rate is very important to know the severity of the disease worldwide. Colon cancer is one of the major causes of cancer-deaths worldwide and has a high tendency to metastasize. The cancer may spread rapidly to some of the major organs like bowel and rectum and may even reach the lungs, kidney or the abdominal areas if not treated in time.
Life expectancy of colon cancer helps to understand the temperament and intensity of cancer cells that develop in the colon. Survival rate is usually calculated for five years after the polyps are detected and diagnosed in the colon. The facts and figures obtained during the process are based on empirical surveys and derived using certain life expectancy calculators.
Life expectancy is an approximate and not exact time period of the patient's survival. Colon cancer survival rate may vary from person to person even though both the patients happen to be suffering from the same stage of colon cancer. The rate of survival is based on various important factors and may change from time to time. Survival rate may also increase or decrease depending upon the dietary patterns of the victim after going through the cancer treatment. Colon cancer has a tendency to recur. Thus, a patient who undergoes regular and thorough medical checkup may live longer than the calculated survival rate as the health recovery is faster as compared to those who are ignorant about their health issues.

Age of the victim is one of the basic factors to be considered seriously while calculating colon cancer survival rate. Colon cancer usually occurs in adults and both men and women are equally prone to it. The risk of being infected by the cancerous cells in the colon increases with age and the chances of recovery gradually decrease as the person gets older.
Health issues other than those developed after cancerous development in the colon also play an important role in deciding the life expectancy of a patient suffering from colon cancer. People who are suffering from sexually-transmitted diseases like Human Papillomavirus (HPV) and Acquired Immune Deficiency Syndrome (AIDS) are highly prone to cancerous infection in the colon. Also, the detection and diagnosis of tumors is more complicated in such cases and recovery from the disorder is slow as compared to the ones not infected by such viruses. Hence, such disorders must be given due importance while calculating life expectancy.
Colon cancer background makes a person more prone to cancer recurrence as well as occurrence. Personal history of cancer puts a person at disadvantage and directly affects his survival rate. The cancer is also hereditary and may pass from one generation to another due to certain genetic causes. Hence, people with such medical background should be very particular about their health checkup schedule as it may directly affect their survival rate.
Immune system is also another major deciding factor in calculating colon cancer life expectancy. Weak immune system actually creates an environment conducive for the cancerous cells to grow with minimum resistance and makes them more prone to redevelopment of cancer tumors in the colon even if treated for the same previously. This directly affects the survival rate of the person and cause severe complications during the cancer treatment. Hence, a strong immune system is a must to improve life expectancy.
Life expectancy and survival rate in numbers
According to colon cancer statistics published by the National Cancer Institute of the United States of America, this cancer is most treatable in the initial stages and the chances of eliminating or curbing the tumors considerably decrease as the disease advances in the higher stages.
In the first stage, the disease is completely curable in almost 90% of the cases and the treatment is quite lenient. The tumors can be treated by normal medication or surgery and do not exhibit any major tendency to reappear. Second stage life expectancy for colon cancer decreases gradually and stands at 85% and 72% for stages 2A and 2B respectively. Colon cancer survival rate is around 83%, 64% and 44% for stages 3A, 3B and 3C respectively. In these stages, the tumors cells begin to metastasize rapidly and attack some of the vital organs like bowel, lungs, rectum and abdominal areas.
Fourth stage is the most severe one and the chances of eliminating cancer tumors in this stage are very less. Just 8% of the people treated in this stage recover safely from the cancer but the chances of regeneration of cancer cells cannot be denied. Exposing tumors to chemicals and strong radiations is the most recommended treatment pattern for this stage. Side-effects of the treatment are the highest in this stage and the victim may suffer from an irreversible damage to his body.
Colon cancer life expectancy and survival rate varies according to geographical locations and also depends upon lifestyle and dietary patterns of an individual. Colon cancer diagnosis techniques are very useful in detecting the polyps early and treating them right in the initial stages. This helps to cure the disease better and also puts a positive impact on life expectancy and survival rate figures.
