Rectal Cancer Life Expectancy and Survival Rate
Rectal cancer life expectancy and survival rate is one of the major concerns of the research organizations focusing on the elimination of rectal cancer by improving the diagnosis and treatment patterns. It is based on a variety of parameters and can be regional or global in nature. Age and geographical location of the victim plays an important role in calculating his chances of survival.
Concept and significance of rectal cancer life expectancy
Life expectancy is an approximate calculation of the number of years a patient suffering from rectal cancer is expected to survive after being diagnosed and cured for the disease. It is based on the condition of the patient at the time of diagnosis and treatment and also considers other vital factors like health disorders and medical history of the person. Life expectancy and survival rate are inter-related form an important basis of cancer research.
Life expectancy is the highest if the disease is detected in the initial stages and treated in an apt manner. Chances of occurrence of rectal cancer increase with age and the disease is prevalent mostly in adults aging 50 years or above. The disease occurs in men and women in almost equal numbers and is not limited to a specific gender.
Understanding life expectancy of rectal cancer is significant in the sense that it reflects the efficiency of the contemporary treatments to cure cancerous development in the rectum. Life expectancy can be different for different stages and may also vary according to the health complications the victim might be suffering from. Important health disorders like human papillomavirus (HPV) and inflammatory bowel disease are prime causes of cancer development in the rectum and need to be taken into account while calculating life expectancy.
The disease is more common in black people and the numbers of rectal cancer-deaths are also high in black people as compared to white ones. Thus, rectal cancer life expectancy and survival rate is lower in such people. Also, the people residing in developed and industrially advanced nations are more prone to the disease as compared to industrially-backward regions.
Concept and significance of rectal cancer survival rate
Survival rate for rectal cancer is the chances of survival of the victim after being diagnosed for cancerous polyps in the rectum. It is usually calculated for five years and is an important indicator of the life expectancy of the victim. Better life expectancy results into better survival rate. Survival rate is based on empirical calculations. Many cancer research organizations consider rectal cancer life expectancy and survival rate as the main variants in improving the standard of treatment to be offered to the victim and thus, indirectly help to minimize his sufferings.
Survival rate, like life expectancy, is the highest in the first stage and fairly high in the initial stages (first and second stage). It decreases considerably as the rectal cancer progresses to higher stages and is the lowest in the fourth stage. It may vary from one person to another and primarily depends upon the immune system of the victim. Persons suffering from non-cancerous disorders like AIDS (Acquired Immune Deficiency Syndrome) and other STDs (Sexually Transmitted Diseases) are highly prone to occurrence as well as redevelopment of cancer cells in the rectum and thus, have a low survival rate.
Some of the factors severely affecting survival rates of the victim are smoking, consumption of red meat and fat-rich food in excess quantity, chewing tobacco, drinking alcohol in excess quantity and ignoring important causes and symptoms of rectal cancer. Improper bowel movements, problems during swallowing and digestion of food, abdominal pains and frequent infections in the colon, rectal, bowel or anal areas are prime indicators of the disease and help in addressing the cancer tumors early.
Survival rate is higher than 90% if the polyps are detected and thoroughly diagnosed in the first stage. The rate falls to almost 65-70% if the disease reaches second stage. Survival rate falls further to around 35% if the tumors are detected in the third stage. Fourth stage is the most severe one and comes with a survival rate of 6%-25% depending upon the health of the patient and efficiency of treatments undergone.
Advantages of understanding rectal cancer life expectancy and survival rate
Rectal cancer life expectancy and survival rate is very important in understanding the scope of rectal cancer in the person's body. It helps to determine the areas and organs in which the tumors have already or are likely to spread and benefits the patient by undergoing diagnosis techniques accordingly. Digital Rectal Exam (DRE), fecal occult blood test and colonoscopy are some of the main diagnosis patterns useful to trace tumors.
Calculation of life expectancy and survival rate also helps to opt for the right form of cure. Chemical and radiation therapy, surgery, immunotherapy, homeopathy and ayurveda are some of the common summary about the treatment of rectal cancer recommended for the disease depending upon its stage and the urgency to eliminate or curb tumors. Better treatment leads to less sufferings to the victim and helps in fast recovery physically as well as mentally. It also helps to minimize the chances of rectal cancer recurrence and leads to better life expectancy and survival rate for the patient.
Rectal cancer life expectancy and survival rate can boost up considerably if a person undergoes regular medical checkup. People with family or personal history of rectal or other types of cancers need to be very particular about their health issues and opt for the right cure well in time. Early diagnosis and treatment for rectal cancer is the key to better life expectancy and survival rate.
