Could someone with no history of rectal bleeding have colon cancer?

The absence of blood in stool does not necessarily indicate colon cancer in the future. Clinical judgment cannot solely rely on a single symptom but requires analysis in conjunction with other symptoms or examinations. Patients are advised to promptly seek medical attention.

1. May Not Be Colon Cancer:

If a patient consumes inappropriate food, such as excessive spicy, irritating, or greasy items like spicy hotpot, fried snacks, etc., causing intestinal irritation, it may result in no blood in stool. After some time, the feces in the intestine may be expelled naturally, indicating no colon cancer involvement.

2. May Be Colon Cancer:

If a patient has colon cancer, it typically leads to congestion and erosion of the intestinal mucosa, altering the consistency and frequency of bowel movements. This may include unformed stools, increased bowel movements, and sometimes accompanied by bleeding, albeit in small amounts. Thus, the absence of prior blood in stool does not exclude the possibility of colon cancer. In this case, colonoscopy, pathological biopsy, and other relevant examinations can aid in a definitive diagnosis.

3. May Be Colon Cancer:

As the tumor gradually enlarges in colon cancer, it can cause compression and irritation symptoms, possibly accompanied by irregular abdominal pain and changes in bowel habits, such as thinner stools. Bleeding may also occur, albeit in small amounts, indicating colon cancer despite no prior blood in stool. Surgical resection, radiotherapy, and chemotherapy may be options under a doctor's guidance.

4. Other Causes:

If a patient has hemorrhoids, it may cause bleeding from the anus but not intestinal bleeding, thus presenting as no prior blood in stool despite the potential for colon cancer. Patients are advised to engage in regular exercise, maintain a balanced and nutritious diet, and avoid spicy and irritating foods. Prolonged bleeding in stool warrants immediate medical attention to avoid delays in diagnosis and treatment.
