As a medical professional with expertise in oncology, I can provide you with information on the symptoms of end-stage colon cancer. It's important to note that symptoms can vary widely among individuals, but here are some common signs that may indicate advanced colon cancer: 1. Blood in the stool: This is often dark red or black and may be accompanied by anemia, which can cause fatigue. 2. Changes in bowel habits: This includes both constipation and diarrhea, which can occur as the tumor grows and affects the normal function of the colon. 3. Stool shape: The stool may become long, thin, and pencil-like as it passes through the narrowed colon. 4. Fatigue and weakness: As the cancer progresses, it can cause a general feeling of tiredness and lack of energy. 5. Abdominal pain or bloating: Pain or discomfort in the abdomen can be a sign of the tumor's presence. 6. Unexplained weight loss: Losing weight without trying can be a sign of cancer as the body's resources are used to fight the disease. Other symptoms may include a feeling of fullness, loss of appetite, nausea, and vomiting. It's crucial for anyone experiencing these symptoms to seek medical attention promptly for a proper diagnosis and treatment. read more >>
