Let's take a look at what are the precursors of colon cancer?

Knowing the signs of colorectal cancer is helpful for people to observe themselves in their daily lives. We should pay more attention to the signs of colorectal cancer. Next, let the experts analyze and introduce to you what the signs of colorectal cancer are. I hope it will be helpful to you.

1. Changes in bowel habits. Changes in bowel habits are the earliest and most common precursor to colorectal cancer. Due to the stimulation of the tumor, the patient may have an increase in the number of bowel movements for no apparent reason or alternating constipation and diarrhea in a short period of time, with a feeling of incomplete bowel movements. As the disease progresses and the lesion grows, the tumor may block the rectal outlet, causing symptoms such as constipation, thinning or deformed stools, and abdominal distension.

2. Changes in stool characteristics. The precursors of colorectal cancer include loose stools, blood in the stool, and mucus. 80% to 90% of rectal cancers may cause blood in the stool, which is bright red or dark red, often mixed with mucus or pus. Sometimes detached tumor tissue can be seen in the stool, but this is often not in the early stage.

3. Seek medical attention early. Once the patient finds the above-mentioned precursors of colorectal cancer, he or she should go to the hospital for examination immediately. When seeing a doctor, be careful not to easily believe the doctor's conclusions without examination, such as hemorrhoids or bacillary dysentery. If the doctor does not require an examination, the patient may as well ask for it himself or herself. Generally speaking, a rectal digital examination can detect more than 75% of rectal cancers, and a simple sigmoidoscopy can detect almost all rectal cancers.
