Cancer Survival Rate

Cancer survival rate is very important to understand the progress of cancer in recent years. Is also gives an idea about the efficiency and reliability of cancer cure and the necessary changes to be made in treatment pattern. Survival rate can be different for different regions and may also depend on the form, origin and intensity of cancer. It is also different for males and females.

What is cancer survival rate?

Survival rate for cancer usually means the chances of survival of a cancer patient after suffering from a particular stage of the disease. The rate is generally calculated for five years after the diagnosis of the disease and may vary according to the health of the victim it is very useful to know the prognosis and life expectancy of a particular type of cancer.

Survival rate plays a vital role in understanding the effectiveness of treatment in a particular stage of the disease and helps to improve the pattern of treatment to be followed for the victim. The survival rate can be absolute or relative in nature and depends upon what kind of output is desired of the study. Survival rate and diagnosis are highly inter-related and efficiency of the later paves way for improvement in the former.

Types of cancer survival rates

Survival rate for cancer can be relative or absolute in nature. Different organizations may consider different rates and usually depend on the aim of study.

Relative survival rate for cancer - In this type of survival rate, the percentage of cancer patients alive for at least five years after diagnosis are divided by the percentage of general people (belonging to the same sex and age) alive after five years. At times, the rate can be even 100% or more as compared to the survival rate of general population taken into consideration. Proper health checkup and prompt medical treatments are the main factors for such a high survival rate. Some cancer victims have better access to best of the medical treatments for cancer and thus, survive more than the general public of their age and sex. This again depends on the type and intensity of cancer and is not universal.

Absolute survival rate of cancer - It is independent of any comparisons and is a simple calculation of the percentage of people surviving in the post-diagnosis of cancer. The period of survival considered to derive survival rate is generally for five years and various parameters like age, sex, geographical location and type of cancer are considered while finding absolute survival rate.

Dimensions of cancer survival rate

Survival rate for cancer can be reliable and efficient only if calculated considering the basic variations and possibilities.

Type and origin of cancer is one of the foremost variations to be considered while calculating a suitable survival rate. Each form of cancer has a unique pattern and pace of growth. Some may metastasize rapidly while some others may not spread at all. These characteristics help in framing a proper survival rate and assist in understanding life expectancy and prognosis better.

Ageof the victim is closely related to the survival rate. Cancer is a cell abnormality that usually occurs in adults and is more common in people above the age of 45 years. Cancer recovery is faster in young adults as compared to old people. Also, the number of health complications increase with age and the ability of the body to fight cancerous infections gradually decrease. Thus, the survival rate also varies accordingly and is better in young people.

Sex is another basic dimension of survival rate for cancer. Cancers occur in different numbers in males and females and may not grow with same intensity and pattern in both genders. Thus, the survival rate also varies accordingly. Some cancers like prostate and penile occur only in males while some others like vaginal, uterine, ovarian and breast occur only in females. Thus, the survival rates considered in such cases are gender-specific.

Geographical factors also put an impact on the overall survival rate of cancer. Different weather conditions, living habits, temperature differences and varied diet pattern and lifestyle are some of the principle deciding factors in the growth of abnormal cells in the body. They may affect the immune system of a person and make him more susceptible to cancer infection.

Immune system has to be considered thoroughly while finding the survival rate for cancer. Some of the health issues like AIDS (Acquired Immune Deficiency Syndrome) and Human Papillomavirus (HPV) have been detected as prime causes in most of the cancers and decrease the chances of survival of the victim. Hence, the survival rate is generally low for people having history of such disorders.

Cancer survival rate facts and figures

United States of America leads the survival rate statistics in both males and females. According to American Cancer Society, the survival rate for breast cancer has shown a dramatic increase in the recent years and is almost 90% if the cancer has spread to areas adjacent to breast while it is 98% in the cases where the cancerous tumors have restricted themselves to a particular area. Lung cancer is one of the major forms of cancer occurring in both males and females. This type of cancer has also shown a considerable improvement over the years and its survival rate stands at around 43%.

Prostate cancers is one of the most treatable cancers worldwide and shown a survival rate of almost 100%. Its 15-year survival rate stands at 82%, 10-year rate at 95% and 5-year rate at 99.6%.

Cancer survival rate has been consistently improving by the virtue of latest cancer treatment patterns and techniques. Though the numbers of cases related to cancer are consistently on rise irrespective of the type and origin of cancer, early detection of tumors have benefited considerably in improving the survival rate. Cancer awareness causes by many support groups and cancer research organizations is also one of the prime reasons for better survival rate of cancer.
