How long does it take for colon cancer to spread?
Colon cancer, or cancer that begins in the lower part of the digestive tract, usually forms from a collection of benign (noncancerous) cells called an adenomatous polyp. Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years.
How do you know if colon cancer has spread?
What are the symptoms of metastatic colorectal cancer?
- a change in bowel habits, such as constipation, diarrhea, or narrow stools, lasting more than a few days.
- blood in the stool, possibly making the stool look maroon or black.
- rectal bleeding of bright red blood.
What organ does colon cancer spread to first?
Colon cancer usually spreads to the liver. It can also spread to the lungs, the lining of the abdomen (peritoneum), the ovaries, the brain, or other organs.
Does colon cancer spread rapidly?
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.
What was your first colon cancer symptom?
A persistent change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool. Rectal bleeding or blood in your stool. Persistent abdominal discomfort, such as cramps, gas or pain. A feeling that your bowel doesn’t empty completely.
How long can you live with untreated colon cancer?
The results showed the median survival of patients to be 24 months (range 16–42). One-year survival was found to be 65% while the 2-year survival was found to be 25%.
Do you feel ill with colon cancer?
You may feel a colicky type pain, or vague discomfort in your abdomen. You may also feel generally unwell, for example listless or tired, because you have been losing blood from the bowel and may have become anaemic (lack of red blood cells).
Can you live a long life with colon cancer?
The majority of patients diagnosed with colon cancer can be treated and will go on to live normal lives. The earlier we identify the lesion, the less likely the tumor will have spread to other parts of your body.
Does Stage 1 colon cancer require chemo?
People with very early colon cancer (stage 1) do not usually need chemotherapy. But this might change after surgery. After your operation, a specialist doctor (pathologist) closely exams your cancer.
Is colon cancer curable at Stage 3?
A stage III colon cancer has about a 40 percent chance of cure and a patient with a stage IV tumor has only a 10 percent chance of a cure. Chemotherapy is used after surgery in many colon cancers which are stage II, III, and IV as it has been shown that it increases the survival rates.
