When considering whether you should get regular colonoscopies if your parent had colon cancer, it is essential to understand the implications of family history on your risk for colorectal cancer. Given that your father was diagnosed with stage 0 colon cancer, this does raise some concerns about hereditary factors that could influence your own risk.

Colorectal cancer can indeed have a genetic component, particularly in cases where a first-degree relative (like a parent) has been diagnosed. The general recommendation is that individuals with a family history of colorectal cancer should begin screening earlier than the standard age of 45. For those with a parent diagnosed with colorectal cancer, especially at a younger age, it is often advised to start screening at least 10 years prior to the age at which the parent was diagnosed. In your father's case, since he was diagnosed at an older age, the recommendation might still be to start screening earlier than the general population guidelines.

You mentioned that you have been undergoing colonoscopies every two years, which is a proactive approach, especially since you have already had polyps removed in previous examinations. The presence of polyps can increase your risk of developing colorectal cancer, and regular surveillance is crucial in these situations. The fact that your previous colonoscopies have been normal is reassuring, but it does not eliminate the need for continued monitoring.

Regarding the advice you received from your family doctor, it is important to note that recommendations can vary based on individual risk factors. While some practitioners may suggest that the risk is not significant enough to warrant frequent screenings, others may take a more cautious approach, especially in light of your family history. It may be beneficial to seek a second opinion from a gastroenterologist who specializes in hereditary colorectal cancer syndromes. They can provide a more tailored recommendation based on your family history and personal health.

As for the issue of anesthesia during colonoscopies, it is common practice to use sedation to ensure patient comfort during the procedure. While there are non-sedated options available, they may not be suitable for everyone, especially if you have anxiety about the procedure or if polyps need to be removed. Discussing your concerns with your gastroenterologist can help you find a balance between comfort and the necessity of regular screenings.

Regarding your other concern about anal itching and the presence of a yellowish discharge after passing gas, this could be related to several factors, including hygiene, diet, or even a mild irritation or infection. It is not uncommon for individuals to experience some degree of anal itching, especially if there is moisture or irritation in the area. However, if this symptom persists, worsens, or is accompanied by other symptoms such as pain, bleeding, or changes in bowel habits, it would be prudent to consult a healthcare professional for a thorough evaluation.

In summary, given your family history of colon cancer, continuing regular colonoscopies is advisable. It is essential to maintain open communication with your healthcare providers about your concerns and to seek specialized advice if necessary. Regular screenings can significantly reduce the risk of developing colorectal cancer by allowing for the early detection and removal of precancerous polyps.
