Carcinoma of early stages also can have bleeding without tenesmus

Carcinoma, or cancer, in the early stages, can sometimes present with bleeding without tenesmus. Tenesmus refers to the feeling of incomplete bowel evacuation, often accompanied by straining and a sense of urgency.

In the early stages of colorectal cancer, when the tumor is relatively small, bleeding may be one of the noticeable symptoms. This bleeding can result in blood in the stool, which may be visible or occult (hidden). The absence of tenesmus does not exclude the possibility of colorectal cancer.

It’s important to recognize that symptoms of colorectal cancer can vary widely, and not everyone with colorectal cancer will experience the same signs or symptoms. Other symptoms may include changes in bowel habits, unexplained weight loss, abdominal pain, and fatigue.

Early detection through screening is crucial for improving outcomes in colorectal cancer. Common screening methods include colonoscopy, fecal occult blood tests, and other imaging studies. If someone is experiencing symptoms that could be related to colorectal cancer, it’s important to seek prompt medical attention for further evaluation and diagnosis.
