Early symptoms of rectal cancer

The early symptoms of rectal cancer may be relatively hidden, but some specific manifestations should arouse our high vigilance. These symptoms include changes in bowel habits, blood in the stool, and a series of systemic symptoms.

1. Changes in bowel habits

Patients with rectal cancer may experience frequent bowel movements, alternating diarrhea and constipation, as well as tenesmus, anal distension and other discomforts. These changes may be early signs of rectal cancer. Once discovered, you should seek medical attention in time.

2. Blood in the stool

Blood in the stool is another important warning sign of colorectal cancer. Unlike blood in the stool caused by hemorrhoids, anal fissures and other diseases, blood in the stool caused by colorectal cancer is often mixed with mucus or pus and blood, and the color may be bright red or dark red, and sometimes even accompanied by blood clots.

3. Systemic symptoms

Rectal cancer patients may also experience systemic symptoms such as anemia, weight loss, fatigue, and low fever. In particular, weight loss without obvious reasons in a short period of time should be taken seriously.

The above symptoms are not specific to rectal cancer and may also occur in other diseases. Once these symptoms occur, you should seek medical attention immediately and undergo professional examinations to confirm the diagnosis.
