Spotting blood in the toilet can be alarming, and while some may be tempted to overlook it, experts emphasize that this symptom warrants immediate attention. In the U.S., colorectal cancer is the fourth most commonly diagnosed cancer, particularly among individuals under 45.
What is rectal bleeding?
Rectal bleeding, or hematochezia, is a symptom often associated with colorectal cancer. According to Dr. Jingquan (Caron) Jia, a clinical associate professor at the University of North Carolina, blood in the stool is one of the two red flag symptoms of early-onset colorectal cancer.
Common causes of rectal bleeding
While rectal bleeding can indicate serious conditions like colorectal cancer, it can also stem from benign causes, including:
- Hemorrhoids
- Hard bowel movements
- Anal fissures
- Diverticular bleeding
Dr. Felice Schnoll-Sussman notes that many reasons for rectal bleeding are benign, but it’s crucial to evaluate any instance of blood in the stool.
Identifying the nature of the bleeding
Blood can appear in various forms, such as:
- Bright red blood mixed with stool
- Black, tarry stool (melena)
The appearance and amount of blood can provide clues about its source. For instance, blood from a tumor on the left side of the colon is likely to be bright red, while blood from the right side may appear darker due to partial digestion.
When to seek medical help
Experts agree that any rectal bleeding should be evaluated by a health care provider. If bleeding is accompanied by other symptoms, such as chest pain, shortness of breath or persistent bleeding, it may indicate a more serious condition requiring immediate medical condition. If bleeding continues for several days, it’s advisable to schedule an appointment with a doctor.
Advocating for your health
Patients, especially younger individuals, may face misdiagnosis due to the nonspecific nature of hematochezia. Dr. Zuri Murrell emphasizes the importance of being proactive in health care. If symptoms persist after treatment for hemorrhoids or other benign conditions, further evaluation is necessary.
The importance of screening
With the rising incidence of early-onset colorectal cancer, regular screening and colonoscopies are vital. These tests can detect blood in the stool that isn’t visible to the naked eye, allowing for early intervention.
While rectal bleeding can be frightening, it’s essential to address the issue rather than ignore it. Early detection of colorectal cancer can lead to successful treatment and improved outcomes. Don’t let fear or embarrassment prevent you from seeking the care you need.
