Blood in stool. Had two bowel movements, otherwise feeling fine?

I am concerned about my age and the likelihood of cancer.
About a year ago, I experienced some intermittent blood in my stool, but it was not very noticeable.
Recently, I noticed blood again during a bowel movement; the stool itself was normal in size, about the thickness of a 50 NT dollar coin, but there was bright red blood when I wiped.
I hadn't mentioned this to anyone before, but after telling my sister, she suggested that I might have colon cancer.
Before she mentioned this, I had been having normal bowel movements, but after hearing her concern, I felt extremely stressed.
Within a few days, I lost my appetite and became anxious and scared.
After about a week, I managed to relax and my appetite returned, but since my sister's comment, I have continued to experience blood in my stool, although there have been a few instances without it.
My bowel habits remain consistent, with regular timing, but the blood has become more pronounced.
Additionally, when my sister first stressed me out, I experienced diarrhea for the first time, which also had blood in it.
Could this be a sign of cancer? I am very anxious and have had trouble sleeping.
I am still young; is there anything I can do? I also have a habit of staying up late.
Thank you, doctor.

When it comes to the presence of blood in stool, it is understandable to feel anxious, especially with concerns about potential serious conditions like cancer. However, it is important to approach this situation with a clear understanding of the possible causes and the appropriate steps to take.

Firstly, blood in the stool can arise from a variety of sources, and not all of them are indicative of cancer. Common causes include hemorrhoids, anal fissures, diverticular disease, and gastrointestinal infections. Hemorrhoids, for instance, are swollen blood vessels in the rectal area that can bleed during bowel movements, often resulting in bright red blood on the toilet paper or in the stool. Anal fissures, which are small tears in the lining of the anus, can also cause similar symptoms.

Given your age and the fact that you have experienced intermittent blood in your stool for over a year, it is crucial to consult with a healthcare professional. While the likelihood of colorectal cancer increases with age and certain risk factors, it is not the only explanation for your symptoms. Stress and anxiety can also exacerbate gastrointestinal issues, leading to changes in bowel habits and the appearance of blood.

Your mention of increased stress following a conversation with your sister about cancer is particularly noteworthy. Stress can lead to gastrointestinal disturbances, including changes in bowel movements and even the onset of conditions like irritable bowel syndrome (IBS), which can manifest with symptoms such as diarrhea, constipation, and abdominal discomfort. It is essential to address both the physical and emotional aspects of your health.

To determine the cause of the blood in your stool, a healthcare provider may recommend several diagnostic tests. These could include a physical examination, a digital rectal exam, and possibly a colonoscopy, which allows for direct visualization of the colon and rectum. During a colonoscopy, the doctor can identify any abnormalities, take biopsies if necessary, and provide treatment options based on the findings.

In terms of cancer risk, while it is true that certain factors such as family history, age, and lifestyle choices can influence the likelihood of developing colorectal cancer, many individuals with similar symptoms do not have cancer. It is essential to focus on obtaining a proper diagnosis rather than jumping to conclusions based on fear or anxiety.

In the meantime, consider adopting healthier lifestyle habits that can support your overall well-being. This includes maintaining a balanced diet rich in fiber, staying hydrated, and managing stress through relaxation techniques such as mindfulness, yoga, or deep breathing exercises. Regular physical activity can also help improve digestive health and reduce stress levels.

In summary, while the presence of blood in your stool warrants attention, it is crucial to consult with a healthcare professional for a thorough evaluation. They can help determine the underlying cause of your symptoms and guide you on the appropriate next steps. Remember, early intervention is key, and addressing your concerns with a medical expert can provide clarity and peace of mind.
