"Signs of Colorectal Cancer: Are These 3 Symptoms Indicative?"

There is no definitive statement that three specific symptoms indicate the presence of colon cancer. Early symptoms of colon cancer are often subtle, but may generally include changes in bowel habits, rectal bleeding, abdominal pain and bloating, weight loss and emaciation, as well as systemic symptoms. If experiencing any discomfort, it is recommended to seek medical attention promptly for relevant examinations. Below are the detailed symptoms:

1. Changes in Bowel Habits:

This is one of the most common early symptoms of colon cancer. Patients may experience an increase or decrease in the frequency of bowel movements, alterations in stool consistency such as thinner or misshapen stools, and sometimes alternating episodes of constipation and diarrhea. These symptoms may be related to intestinal dysfunction caused by colon cancer.

2. Rectal Bleeding:

Colon cancer patients may experience rectal bleeding due to the rich blood vessels on the tumor surface, which are prone to rupture and hemorrhage. The color of the blood may vary depending on the location of the bleeding, ranging from bright red to dark red or black.

3. Abdominal Pain and Bloating:

Colon cancer patients may experience abdominal pain and bloating, which may be associated with the tumor's growth within the intestine, obstruction of the intestinal tract, or intestinal spasms. Abdominal pain may be intermittent, dull, or paroxysmal, and sometimes accompanied by cramping.

4. Weight Loss and Emaciation:

Due to intestinal dysfunction and decreased appetite, colon cancer patients may experience weight loss and emaciation. This occurs because the body is unable to absorb sufficient nutrients from food, leading to malnutrition and weight reduction.

5. Systemic Symptoms:

In addition to the above-mentioned local symptoms, colon cancer patients may also exhibit systemic symptoms such as fatigue, weakness, and anemia. These symptoms may be related to the body's consumption and malnutrition caused by colon cancer.

Although the early symptoms of colon cancer are not typical, patients should seek medical attention promptly upon experiencing changes in bowel habits, rectal bleeding, abdominal pain and bloating, weight loss and emaciation, as well as systemic symptoms. Through comprehensive treatment measures and adjustments to lifestyle, colon cancer patients can achieve certain therapeutic effects and maintain their quality of life. Regular physical examinations, particularly for individuals over 40 years old, are also recommended to facilitate early detection and treatment of colon cancer.
