6 silent symptoms of colorectal cancer that are often overlooked
(Baonghean.vn) - Colorectal cancer originates from the inner lining of the intestine in the form of polyps (stalked fleshy buds), which gradually protrude into the intestine. Most early signs of colorectal cancer are not noticed, so in many cases the disease is diagnosed at a late stage, when it cannot be cured... If you see any of the following symptoms, do not hesitate to see a doctor.
 |
| Anemia can be the first warning sign of colorectal cancer, even if the body does not show any other symptoms. The cause of anemia is due to cancer causing internal bleeding in the body… Therefore, people need to see a doctor when they detect symptoms of anemia such as fatigue, paleness, dizziness. |
 |
| If something is blocked or obstructed in the colon, it can cause a feeling of fullness. Symptoms of bloating and stomach cramps can come from many different causes. But if these symptoms persist, it could be a sign of colorectal cancer… You should see a doctor immediately if you have constant pain on the right side of your abdomen - this is a sign that the disease is progressing to the final stage. |
 |
| Constipation is nothing to worry about, but if it is severe and persistent, it could be a warning sign of colorectal cancer. The cause of constipation could be a tumor blocking the stool in the intestine. |
 |
| Colon polyps are small clumps of cells on the lining of the colon that can develop into cancer over time. When polyps become cancerous, they can grow into obstructions that make stools narrower than normal. If you notice stools as thin as a pencil, you should be on high alert. |
 |
| Sudden weight loss is often a symptom of some types of cancer including colon cancer. You should pay attention when your body loses about 5 kg or more in less than 6 months without knowing the reason… Cancer cells change the process of converting energy from food, which can cause sudden and rapid weight loss depending on the progression of the disease. |
 |
| Regarding systemic symptoms, colorectal cancer progresses slowly but also causes discomfort to the patient's daily activities very early on, such as: loss of appetite; nausea, vomiting; jaundice, weakness and fatigue... The above symptoms depend a lot on the location of the primary tumor. |
