Colon cancer in the elderly
The colon is the final part of the digestive tract. Colon cancer typically affects older adults, though it can happen at any age. It usually begins as small, noncancerous (benign) clumps of cells called polyps that form on the inside of the colon. Over time some of these polyps can become colon cancers.
Symptoms Of Colon Cancer In The Elderly Change in bowel regular bowel movements such as diarrhea or constipation . Need to have a bowel movement that reoccurs even after having one. Bleeding of the rectum. Stool with blood in it. Stools that are dark in color. Stomach cramping or pain. Fatigue or a feeling of weakness.
The 5-year survival rate of people with localized stage colorectal cancer is 90%. About 39% of patients are diagnosed at this early stage. If the cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 71%.
The aim of our study was to contribute to a better understanding of the biology of colorectal cancer . Our findings indicate that this is a slow-growing disease with a 65% survival rate after 1 year, and a 25% survival rate after 2 years (10/40 patients).
Stage 3 or 4 symptoms (late stage symptoms ) unexplained weakness. unintentional weight loss. changes in your stool that last longer than a month. a feeling that your bowels won’t completely empty.
Signs and symptoms of colon cancer include: A persistent change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool.

Usually, the stools ( poop ) of the patients with colon cancer may have the following characteristics: Black poop is a red flag for cancer of the bowel. Blood from in the bowel becomes dark red or black and can make poop stools look like tar.
Stage IV colon cancer has a relative 5- year survival rate of about 14%. This means that about 14% of people with stage IV colon cancer are likely to still be alive 5 years after they are diagnosed. But you ‘re not a number. No one , including your doctor, can tell you exactly how long you ‘ll live .
“It takes them a good while to figure out how to become a carcinoma, which is a cancer that can metastasize.” But if a tumor develops into a carcinoma with the ability to metastasize, it will progress to metastasis quickly . This transformation occurs within about two years, before another mutation can develop .
One of the deadliest cancers can be prevented or detected at a curable stage if you follow recommended screening guidelines. Colon cancer is the second most common cause of cancer deaths in the United States, according to the American Cancer Society (ACS).
How long someone lives with mesothelioma without treatment depends the cancer’s stage , their overall health and tumor growth rates. Patients diagnosed with stage 1A disease who elect no treatment live an average of two years. Those diagnosed in stage 4 who decide against treatment live an average of 6 months.
What are the early warning signs of colon cancer? A persistent change in bowel habits. Narrow or pencil-thin stools. Diarrhea or constipation. Blood in the stool, rectal bleeding (blood may appear as bright red blood or dark stools) Persistent abdominal pain or discomfort, such as cramps or bloating.
Left untreated , these colon cancers grow and eventually spread through the colon wall to involve the adjacent lymph nodes and organs. Ultimately, the cancer cells spread (metastasized) to distant organs such as the liver, lungs, brain, and bones.
Not everyone dying of cancer has pain . But if they do, it can usually be well controlled and people can be kept very comfortable. The doctors and nurses looking after the dying person will do all they can. Sometimes restlessness is a sign of being in pain .
If the colon cancer has spread too far for surgery to be effective, chemotherapy is the primary treatment option. Most people with stage 4 colon cancer will receive chemotherapy or specific targeted therapies to help control the cancer progression or symptoms.
In 20 to 25% of patients at the time of diagnosis, hepatic metastatic disease can be identified clinically, and 40 to 50% will develop during the first 3 years after the primary tumor is diagnosed. Pulmonary or liver metachronous metastasis will develop in 8 to 13% of patients after surgical resection.
