Anal Cancer Life Expectancy

Cancer » Anal Cancer » Anal Cancer Life Expectancy

Anal cancer life expectancy is one of the important factors in judging the severity of the disease. Calculating fairly accurate life expectancy requires a thorough research of anal cancer. One needs to do a detailed comparison of various cases concerned with the cancer of anus to reach the most logical prediction of life expectancy.

Meaning of anal cancer life expectancy

Life expectancy of anal cancer is one of the major concerns of many anal cancer patients. Outcome of the study of life expectancy can be very useful in anal cancer support and prognosis. Calculation of life expectancy is a tedious process and is highly sensitive. It may vary with times and usually depends upon the conditions in which the tumor cells grow.

Life expectancy can be calculated using various calculators and is a scientific process. Specific parameters and conditions are taken into consideration to bring uniformity in the calculation process. Life expectancy calculations can be more accurate if the conditions and severity of the cases considered as samples are varied and belong to different areas. Regional life expectancy for anal cancer may vary from that at the global level and depends upon a variety of factors.

Life expectancy is an approximate and not accurate calculation of survival period of the victim. Thus, it may vary from person to person and one may live even more than the life expectancy period. It all depends upon how the person is treated and what precautions are taken to avoid redevelopment of cancerous tumors.

Parameters of anal cancer life expectancy

Anal Cancer Life ExpectancyAnal cancer cases occur mostly in women and are more common in adults aged over 45 years. Men are comparatively less prone to the disease. Also, the life expectancy may be different in men and women depending upon their age and previous medical history. People who have been treated for anal or any other cancer in the past may not have life expectancy as high as the first-time cancer patients.

Presence of human papillomavirus (HPV) and infection from AIDS (Acquired Immune Deficiency Syndrome) and other sexually transmitted diseases is also taken into consideration for calculating life expectancy. A person suffering from such diseases is more prone to rapid spread of cancerous tumors. This may impact life expectancy rate severely.

Nature of tumors and their origin also play a vital role in calculating life expectancy. Tumors can be benign or cancerous and the life expectancy of anal cancer patient depends upon which tumor he is suffering from. It is more in benign tumors as compared to the cancerous or malignant ones and is calculated in a different manner for both the cases.

Also, cancer of the anus can be primary or secondary in nature. Primary anal cancer develops in the anus and spreads to other areas of the body at a later stage. Secondary anal cancer is the disorder in which the cancerous cells develop in various areas of the body like lungs, liver, blood, lymphoma, abdomen, etc and reach the anus through metastasis. In secondary anal cancer, the areas infected by cancerous cells are much more as compared to those in the primary anal cancer at any given time. Hence, life expectancy is lower in the secondary anal cancer.

Approximate rates of anal cancer life expectancy

Anal cancer is curable if detected in the initial periods of cancerous development in the anus. Thus, life expectancy rate is highest in the initial stages of anal cancer and go on decreasing as the stage progresses. Survival rate of anal cancer is quite fair as compared to other cancers. Squamous type of anal cancer has high life expectancy as compared to the non-squamous ones. As per the studies conducted by American Cancer Society, life expectancy for squamous anal cancer can be as high as 71% in stage 1 and drops gradually to 64%, 48%, 43% and 21% in stage 2, 3A, 3B and 4 respectively. Non-squamous anal cancer has comparatively low survival rates and is around 59%, 53%, 38%, 24% and 7% respectively for the stages mentioned above.

Anal cancer life expectancy is highly beneficial in making a patient aware of anal cancer prognosis and the most feasible treatments available. Diagnosis techniques like endoanal ultrasound, anoscopy, digital rectal exam, proctoscopy, fine needle aspiration biopsy and magnetic resonance imaging (MRI) scan play an important role in easing the process of calculating anal cancer life expectancy.
