Rectal Cancer Treatment and Cure
Rectal cancer treatment and cure is vital to increase the life expectancy of the person. It also puts a positive impact on the overall survival rate of the disease and helps in minimizing the number of cases of rectal cancer worldwide. Cure patterns may vary according to the case and geographical location of the victim. Rectal cancer risk factors are based on a variety of factors and all such important factors need to be examined thoroughly before recommending a particular cure pattern.
Rectal cancer treatment and cure significance
Rectal cancer is a severe cancerous disorder developing in the rectal or other adjacent areas and amounts to a considerable number of cancer-deaths globally. It is the third-most common type of cancer and the numbers of cases are rising consistently. The disease is more common in nations that are industrially advanced and highly developed. Males and females are almost equally prone to the disease and the cases are usually detected in people older than 50 years.
Rectum is one of the most important areas of human digestive system. It is located at the end of the colon and performs the critical function of sorting water, carbohydrates and other nutrients like vitamin, proteins and fats from the food passed through rest of the digestive system and forwards the waste for elimination. This helps to fulfill regular body requirements of nutrients and keeps the body cells and tissues healthy.
Tumor development in the rectum may hamper the cell development mechanism and disturb coordination between various parts of the body including the digestive system. It also creates complications in smooth passage of body waste through the anus. Hence, detection and eliminations of tumors in the initial phases is extremely important.
Tumors can be cancerous or non-cancerous and depend on the status of cell abnormality. Non-cancerous tumors can also be pre-cancerous or benign. Such tumors do not damage rectal cells and tissues but may form lumps similar to the cancerous ones and create obstructions in rectal functioning. Such tumors are easy to cure by surgery and do not require and stringent measures. Their chances of redevelopment are almost negligible and do not cause any permanent damage to the body. Such tumors may fall prey to cancerous infection if not eliminated in time.
Cancerous tumors are the ones that cause maximum damage to the victim and disturb the smooth functioning of his digestive system. They can be rarely eliminated by surgery as the scope of infection is quite vast and the malignant cells have a tendency to metastasize. Such tumors can recur easily and stern therapies like exposure to chemicals and radiations are necessary to tackle them effectively. Recurrence is more dangerous than occurrence as the recovery becomes increasingly difficult and complicated if a person undergoes harsh treatments for cancerous development in the rectal areas more than once. They may also lead to permanent disabilities in the person's body.
Important forms of rectal cancer treatment and cure
Rectal cancer treatment and cure pattern mainly develops on the intensity and size of tumors and the phase of cancer the victim is undergoing. Survival rate for the disease is very high (more than 90%) if the polyps are properly diagnosed and treated in the initial phase. It considerably dips to less than 25% if the victim undergoes diagnosis and treatment for the same in the late phases. Hence, early treatment for rectal cancer leads to better rate of survival and less chances of recurrence.
Common surgery for rectal cancer is the basic and widely followed type of rectal cancer treatment if the tumors are benign, pre-cancerous or non-cancerous. The treatment is also effective if the tumors are detected and diagnosed in the first two stages of the disease. Surgery can be for partial or complete removal of the organ and depends upon the size and location of tumor. Polypectomy, resection and local excision are some of the basic forms of surgery. Colostomy is also useful in getting rid of cancerous invasion in the rectum. Pelvic exenteration and anastomosis have been proved to be reliable for curing rectal cancer if undergone at proper time.
Surgeries can be preventive, curative, diagnostic, palliative or reconstructive. Pattern of surgery may contain one or more forms of surgeries and the ultimate aim is to prevent cancer or curb chances of occurrence as well as recurrence of cancer cells. Surgeries can also be conducted simultaneously with radiotherapy or chemotherapy if the chances of tumor-elimination are considerably high.
Radiotherapy is another important form of treatment. In this cure pattern, the tumors are exposed to powerful radiations and the tissues and cells present in the infected areas are damaged by burning. This may also lead to burning the region adjacent to the infected areas in order to prevent redevelopment or spread of infected cells in other areas of the rectum. The cure is usually recommended in advanced phases of the disease and may cause severe side-effects to the person.
Chemotherapy is also an important form of rectal cancer treatment and is conducted by killing the tumors through chemical treatments. It is a stern type of treatment and is more effective in higher stages of the disease. Side-effects of the treatment need to be checked well before recommending it to a particular victim.
Rectal cancer treatment and cure can be highly beneficial in eliminating cancerous tumors if backed by standard and efficient detection and diagnosis methods. Colonoscopy, magnetic resonance imaging (MRI) scan and digital rectal exam (DRE) can be very effective in early detection of lumps in the rectal areas. Regular medical examination, strong immune system and balanced diet along with active lifestyle can reduce the chances of cancerous attack in the rectum enormously.
