What Is Colorectal Cancer?(Colon Cancer Stages)
(Colon Cancer Stages)Colorectal cancer is one of the most common non-skin cancers identified in men and women and is the second highest cause of deaths due to cancer. However, colorectal cancer is greatly curable in their early stage if detected. The cause of colorectal cancer cells that form in the lining of the colon.(Colon Cancer Stages)
How Colorectal Cancer Starts(Colon Cancer Stages)
Colorectal cancer starts as a benign growth known as a polyp. Adenoma is a type of polyp and is benign tumors of the tissue coating the colon or rectum. Some adenomas have the capacity to turn into cancer in the long term. Removal of this in early time helps to prevent them from turning into cancer.
Non-controllable Risk Factor Colorectal ancer(Colon Cancer Stages)
There are some risks factors which can create colorectal cancer are Non-controllable and are not in our control. These are
- Inflammatory bowel disease
- Colon polyps
- over 50 years
- Family antiquity of colorectal cancer
- Breast or ovarian cancer History
Controllable Risk Factors(Colon Cancer Stages)
The factors which can cause colorectal cancer can be controlled by avoiding our habit and changing our living style. They are
- Eating a diet high in red or processed meat and eating meat cooked at high temperatures.
- Overweight or obesity
- Inadequate exercise
- Cigarette smoking
- Drinking alcohol
Warning Signs of Colorectal Cancer(Colon Cancer Stages)
Colorectal cancer in early stages generally doesn’t show any symptoms. By Screening can detect cancer before it crops symptoms and at this time it is most curable. When disease begins to spread, it produces blood in the stool, bowel patterns changes like diarrhea or constipation, stomach pain, weight loss, or tiredness. Tumors that cause symptoms are characteristically larger and tougher to treat.
Colorectal Cancer Screening(Colon Cancer Stages)
It is suggested most people should have colonoscopy screening every 10 years from the age 50. A tiny camera is used in colonoscopy examination of the entire colon and rectum. This test helps to find cancers in their early stage which is most treatable. At this stage by removing polyps cancer can be prevented from developing. An alternative to colonoscopy is CT scan images to imagine the colon and it is known as a virtual colonoscopy.
Colorectal Cancer Diagnosis(Colon Cancer Stages)
If abnormalities found in the colon or rectum, biopsies are done to identify the presence of cancer. This can be done through a colonoscopy. An examination of tissue is done microscopically to look for cancer cells.
Colorectal Cancer Staging(Colon Cancer Stages)
In determining the level of tumor spread beyond its original location staging is done. However, Staging is not be related to the size of the tumor. Treatment of disease depends upon the stage of a tumor. Staging for colorectal cancer is as follows:
- Stage 0 – cancer exist only in the innermost lining of the rectum or colon.
- Stage I –not spread beyond the inner wall of the rectum or colon.
- Stage II – spread into the muscle layer of the rectum or colon.
- Stage III – spread to at least one lymph node in the area.
Survival Rates for Colorectal Cancer(Colon Cancer Stages)
Patients with stage I colorectal cancer survive for 5-year(74%) while this rate drops to 6% in case of Stage IV tumors.
Colorectal Cancer Surgery(Colon Cancer Stages)
Colorectal cancer is generally treated by removing the tumor and surrounding tissues. Surgery cures colorectal cancer if the tumors are of the early stage. The tumors that have spread outside the colon, even surgery may not cure the condition, however; removing larger tumors may reduce symptoms.
Advanced Colorectal Cancer Treatment(Colon Cancer Stages)
Colorectal cancer spread to the lymph nodes (stage III) can occasionally be cured. In this situation treatment usually consists of surgery and chemotherapy for colon cancer. In cases of rectal cancer, the radiation therapy is applied both prior to and following surgery in more advanced cases. it is harder to treat or cure if cancer return after treatment or spread to other organs. The treatments may relieve the symptoms and prolong life to some extent.
Coping With Chemotherapy(Colon Cancer Stages)
Modern chemotherapy drugs cause less nausea and other worrying side effects than older drugs. To control these side effects medications are also available. More Medical trials are developing better tolerable chemotherapy.
Radiofrequency Ablation(Colon Cancer Stages)
Radiofrequency ablation (RFA) is used to destroy tumor tissue. For the insertion of a needle-like device into the tumor, CT scanning is used, through which intense heat is applied. RFA is a better option for destroying tumors.. That patient who has scarce metastatic tumors in the liver cannot be removed by surgery. In this case, chemotherapy is occasionally combined with RFA to terminate the tumors.
Colorectal Cancer Prevention: Diet(Colon Cancer Stages)
According to researchers taking nutritious diet, doing ample exercise, and maintaining body fat could prevent 45% of colorectal cancers. That is adopting a healthy lifestyle can affectedly lower the risk of getting colorectal cancer.
Preventing Cancer with Exercise(Colon Cancer Stages)
One study said that people will have 24% fewer chances of getting colorectal cancer who do most physical exercise. According to American Cancer Society at least 30 minutes of exercise, a day for 5 or more days a week could help to remain healthy.
