14. Bloating and Gas That Persists
While occasional bloating is normal, persistent bloating—especially if it's a new development—can indicate a growing tumor affecting normal digestive function. The tumor may cause partial blockages that trap gas in the colon, creating chronic distension and discomfort.
This bloating often feels different from typical post-meal fullness. It may persist throughout the day or worsen as the day progresses. If your abdominal area feels consistently distended or tight, and over-the-counter remedies don't provide relief, this could signal something more serious than simple digestion issues.
13. Mucus in Your Stool
The presence of visible mucus in your stool—appearing as a clear, jelly-like substance—can indicate irritation or inflammation in the colon. While small amounts of mucus are normal, a noticeable increase or persistent presence is a red flag.
Mucus production increases when the colon is irritated or when a tumor is growing. If you observe this change and it persists for more than a week, it's worth discussing with your doctor. This symptom is often overlooked but can be one of the earlier warning signs of colon issues.
12. Anemia Symptoms (Pale Skin, Shortness of Breath)
Beyond simple fatigue, colon cancer can cause anemia through chronic blood loss, leading to noticeable physical symptoms. These include unusually pale or sallow skin, persistent shortness of breath, dizziness, or a feeling of lightheadedness—especially when standing up quickly.
Anemia reduces the oxygen-carrying capacity of your blood, leaving you feeling weak and exhausted. If you notice your complexion has become noticeably paler or you're experiencing unexplained breathlessness during normal activities, have your blood iron levels checked. These symptoms, when combined with other warning signs, strongly suggest the need for colon cancer screening.
