Rectal Cancer Therapy
Rectal cancer therapy paves the way for safe and complete elimination of tumors from the rectum and also helps to minimize the chances of their recurrence. Therapy can be of various types and needs to be recommended according to the immune system and sustainability of the victim. Preventive cure or eliminating tumors right in the pre-cancerous stage is also an important form of therapy and needs to be undertaken under thorough medical supervision.
Meaning and importance of rectal cancer therapy
Therapy for rectal cancer is an apt form of treatment followed to treat the tumors that generate in the rectal areas or any other organs adjacent to it like bowel, anus, colon, abdomen, liver and lungs. Most of the cases of rectal cancer are of adenocarcinoma type and originate in the tissues present in the glandular areas of the rectum. Such type constitutes more than 98% of the overall cases and can be fatal if not detected in the initial phases.
Rectal cancer is very common in industrialized countries and black people have higher death-rate as compared to white ones as far as deaths due to rectal cancer are concerned. The disease occurs almost in equal numbers in men and women and is fully curable if detected early. People above 50 years of age are more prone to cancer of the rectum as compared to young ones. Also, the health complications in older people are high in older people. This makes the detection and diagnosis of tumors difficult and time-consuming. Hence, timely medical checkup is the key to make you safe from the disease.
Tumors formed in the rectum can be benign or cancerous. Also, the cancer can be primary or secondary in nature may originate or metastasize to any areas of the rectum. Secondary cancer of the rectum can cause severe damage to the body cells and tissues and create complications in normal body movements. Also, the tumor cells are quite similar in appearance to the normal and healthy body cells. Thus, sorting normal cells from the infected ones is another big concern and prevents the tumors from being detected in the initial phases. All such complications lead to severe metastasis of tumors and increase the chances of their recurrence even if treated in the past.
Therapy for rectal cancer is a process to overcome all such irregularities occurring in the rectum in a systematic and planned manner and tries to eliminate or curb the cancerous infection at the earliest. It also helps to minimize the sufferings of the patient by treating the cancer cells in a manner suitable to him thus, enabling the victim to recover faster physically as well as mentally.
Therapy can be of various forms and intensities and usually takes important factors like personal habits and lifestyles of the person into consideration. Efficiency of therapy is also dependent on many other non-cancerous disorders that the person might be suffering from. Human papillomavirus (HPV) and AIDS (Acquired Immune Deficiency Syndrome) are some of the main risk factors for cancerous generation in the rectal or colon areas and may hamper the effectiveness of therapies undertaken.
Types of rectal cancer therapy
Surgery is the most basic and significant type of therapy for rectal cancer. It can be by the way of local excision, colostomy, resection or polypectomy. Recent developments in the field of rectal cancer research have also come up with some of the important forms of surgical methods like diagnostic, preventive or reconstructive surgery. Palliative surgery is also practiced to minimize the sufferings of the victim and enable fast recovery. Surgeries can be of optimum benefit if conducted in the early stages of the disease. They come with very few side-effects and have a high success rate. Surgery can be done simultaneously with radiation or chemical therapy if the situation permits.
Chemotherapy or chemical treatment is another form of therapy practiced to tackle rectal cancer. This kind of approach treats tumors by exposing them to certain strong chemicals. Infected areas are treated well in this form of approach but the organs or areas adjacent to the treated ones are also severely affected by the chemicals making them more vulnerable to cancer recurrence. This therapy is practiced if the tumors are not treatable by rectal surgery alone.
Radiotherapy is the sternest form of therapy recommended for cancerous development or recurrence in the rectum. Tumors are exposed to strong radiations that damage or kill the malignant cells or polyps. Some of the areas adjacent to the infected areas are also exposed to radiations in order to minimize the risk of regeneration of cancerous cells in such areas. Radiotherapy comes with a high number of side-effects and should be undergone only if no other option is left.
Immunotherapy is a form of treatment in which the rectal cancer tumors are treated by boosting the natural resistance of the victim. Targeted therapy is a contemporary form of treatment in which only the infected cells are targeted without causing any major damage to the adjacent normal healthy cells and tissues.
Hormonal therapy is another uncommon but important form of therapy for rectal cancer and treats the tumors by manipulating the hormonal growth.
Ayurvedic and homeopathic therapies are also useful in reducing the impact of rectal cancer cells on the victim's health and also act as good curative techniques in post-treatment period. These therapies are very useful in minimizing the side-effects of rectal cancer treatments and help in overcoming physical and mental sufferings caused to the victim.
Rectal cancer therapy can be a boon if taken at the right time and according to prescribed pattern. Therapies can also be used in various combinations suitable to the victim and play a main role in preventing redevelopment of malignant cells in the rectum. Proper detection and diagnosis of the disorder is the backbone of therapy and should be undergone using latest and reliable methods. Strict medical supervision along with regular medical checkup is the key to an efficient therapy for rectal cancer.
