Changes in bowel habits can be indicative of various underlying health issues, particularly when there is a family history of colorectal cancer, as in your case. It is essential to understand that alterations in bowel patterns—such as frequency, consistency, and the presence of blood or mucus—can signal the need for further medical evaluation.

In your situation, the sudden increase in bowel movements from once a day to three times a day, particularly concentrated in the evening, along with the sensation of incomplete evacuation and the presence of blood, raises several concerns. The fact that you have a family history of colorectal cancer, with your grandmother having passed away from it and your father having polyps, adds an additional layer of risk that should not be overlooked.

The symptoms you describe, including the feeling of residual stool, the presence of blood, and the occurrence of mucus in your stool, could be associated with several conditions. These may include:
1. Hemorrhoids or Anal Fissures: Given your history of anal fissures, it is possible that these could be causing the bleeding. Hemorrhoids can also lead to similar symptoms, including pain and bleeding during bowel movements.

2. Irritable Bowel Syndrome (IBS): This functional gastrointestinal disorder can lead to changes in bowel habits, including increased frequency and the sensation of incomplete evacuation. Stress and dietary factors often exacerbate IBS symptoms.

3. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause changes in bowel habits, abdominal pain, and the presence of blood or mucus in the stool. These conditions require prompt diagnosis and management.

4. Colorectal Cancer: Given your family history, any significant change in bowel habits, especially with the presence of blood, should be evaluated for the possibility of colorectal cancer. Early detection is crucial for effective treatment.

Considering these factors, it is highly advisable to seek a consultation with a gastroenterologist. They may recommend a colonoscopy, which is a critical diagnostic tool for examining the colon and rectum for abnormalities, including polyps or cancer. Additionally, stool tests, including fecal occult blood tests, can help identify hidden blood in the stool, which may not be visible to the naked eye.

In the meantime, it is essential to monitor your symptoms closely. Keep track of any additional changes in your bowel habits, the characteristics of your stool, and any other symptoms such as abdominal pain, weight loss, or changes in appetite. This information will be valuable for your healthcare provider in making an accurate diagnosis.

Furthermore, lifestyle modifications may help alleviate some symptoms. These can include:
- Dietary Changes: Increasing fiber intake through fruits, vegetables, and whole grains can help regulate bowel movements. However, if you suspect IBS, you may need to identify and avoid trigger foods.

- Hydration: Ensure you are drinking enough fluids, as dehydration can worsen constipation and lead to straining during bowel movements.

- Stress Management: Since stress can exacerbate gastrointestinal symptoms, consider incorporating relaxation techniques such as mindfulness, yoga, or regular physical activity into your routine.

In conclusion, changes in bowel habits, particularly with a family history of colorectal cancer, warrant a thorough evaluation by a healthcare professional. Early diagnosis and intervention can significantly improve outcomes, so do not hesitate to seek medical attention.
