Early symptoms of colorectal cancer?

Four months ago, I experienced symptoms of dark stools with fresh blood.
There was one occasion where I only passed mucus, and sometimes I felt dizzy, which I wasn't sure was due to staying up late.
I consulted a doctor at that time who diagnosed me with internal hemorrhoids, and I eventually returned to normal.
However, recently, about a week ago, I noticed fresh blood again after wiping, but this occurred during a period of diarrhea when I was experiencing anal pain.
I researched and found that my previous symptoms could align with those of colorectal cancer.
I would like to know what I should do.

Hello: The likelihood of developing colorectal cancer at the age of 16 is extremely low.
It is advisable to monitor for any signs of anal fissures or the possibility of hemorrhoids due to prolonged sitting, as well as to check for constipation or harder, larger stools.
If there are still concerns and persistent bleeding, you may consult a pediatric gastroenterologist for further evaluation by a clinical physician.

More Info

Understanding early symptoms of colon cancer is crucial for timely diagnosis and treatment. Colon cancer, also known as colorectal cancer, can present with a variety of symptoms, and recognizing these early signs can significantly impact outcomes.
Firstly, it's important to note that early-stage colon cancer may not present any symptoms at all. However, as the disease progresses, certain signs may become apparent. Common early symptoms include:
1. Changes in Bowel Habits: This can manifest as persistent diarrhea or constipation, or a change in the consistency of your stool. You mentioned experiencing black stools and mucus, which can be concerning. Black stools may indicate bleeding in the upper gastrointestinal tract, while mucus can be a sign of irritation or inflammation in the colon.

2. Blood in Stool: Any presence of blood, whether bright red or dark, should be taken seriously. Bright red blood often indicates bleeding from the lower gastrointestinal tract, while dark blood may suggest bleeding higher up. You mentioned having fresh blood during bowel movements, which is a symptom that warrants further investigation.

3. Abdominal Discomfort: This can include cramping, gas, or pain. If you experience persistent abdominal pain or discomfort, it could be a sign of an underlying issue.

4. Unexplained Weight Loss: Losing weight without trying can be a red flag for many types of cancer, including colon cancer.

5. Fatigue: Feeling unusually tired or weak can be a symptom of various health issues, including cancer.

6. Narrowing of the Stool: You noted that your stool has become thinner. This can sometimes indicate a blockage in the colon, which may be caused by a tumor.

Given your history of symptoms, including the recent occurrence of blood and mucus, it is advisable to seek medical attention promptly. A healthcare provider may recommend a colonoscopy, which is a critical tool for diagnosing colon cancer. During this procedure, the doctor can visualize the colon and rectum and take biopsies of any suspicious areas.

In addition to a colonoscopy, other diagnostic tools may include imaging studies such as CT scans or MRIs, which can help determine the extent of any disease present. Blood tests may also be conducted to check for anemia, which can occur due to chronic blood loss.

As for your question about how long to observe symptoms before seeking medical help, it is generally recommended that any concerning symptoms, especially those involving blood, should be evaluated by a healthcare professional as soon as possible. Delaying evaluation can lead to progression of the disease, which may complicate treatment options.

In summary, while some symptoms may be attributed to less serious conditions, the presence of blood, changes in bowel habits, and abdominal discomfort should not be ignored. Early detection is key in managing colon cancer effectively, and your proactive approach to monitoring your symptoms is commendable. Please consult with a gastroenterologist or your primary care physician to discuss your symptoms and the need for further evaluation.
