What should I do if I suspect I have colon cancer? Can a colonoscopy confirm whether I have colon cancer?

Sometimes, through the Internet or reading other people's descriptions, many people are very careful about whether they have certain diseases when comparing their own situations. For example, if the frequency of bowel movements increases, they are careful about colorectal cancer. Experts say: It is right to be nervous, but don't be too nervous, because many diseases can cause it, not just colorectal cancer. However, while being nervous, you should also pay attention to taking action, such as going to the hospital for a check-up, so that you can feel at ease. So, what are the specific symptoms of colorectal cancer? What kind of examinations are needed? Let's take a look at it together.

What are the symptoms of colorectal cancer?

1. Blood in the stool

Basically, every patient with this disease will experience this condition, but because each person's actual situation is different, some will be milder and some will be more serious. Generally, mild cases will only manifest as occasional bleeding. Severe patients will have mucus and blood in the stool, mucus, pus and blood in the stool, or fresh blood in the stool. They are often misdiagnosed as dysentery or hemorrhoidal bleeding, thus missing the best time for treatment.

2. Changes in bowel habits and abdominal pain

This is actually very easy to understand, and it is also a condition that most patients will experience. For example, if you used to have a bowel movement once a day, but in a short period of time, you have to go to the toilet three or four times a day for no apparent reason, and the stool has also changed in nature, that is, it was round in most cases, but now it has become flat; or if diarrhea and constipation occur alternately, then you should be careful of colorectal cancer. In addition, patients may also experience abdominal pain, which is mainly sporadic.

Experts suggest: Instead of always worrying, it is better to have a colonoscopy and buy peace of mind

If you have the above conditions, it is useless to worry about it, because it will only add psychological burden to you without any practical help to you. Therefore, it is better to go to the hospital for an examination, so that you can feel at ease. If not, don't keep thinking about it. If it is, then treat it in time, so that you can also strive for early recovery. Generally speaking, colonoscopy is the most accurate way to diagnose colorectal cancer, because colorectal cancer is mostly caused by the gradual enlargement of polyps, and colonoscopy can not only find polyps, but also cut them off immediately, bringing cancer prevention and control forward. Therefore, experts recommend that people over the age of 45 should have a colonoscopy once a year. If they are at high risk of colorectal cancer, they should be 40 years old in advance. If you have a colonoscopy and the results are healthy, then you can feel at ease in the short term. However, many people are afraid of colonoscopy, feel very painful and terrible, and then refuse to do it. In fact, with the continuous improvement of colonoscopy technology, the probability of perforation during colonoscopy is very low, and the pain during colonoscopy is also very light. Of course, if the patient really has poor tolerance, a painless colonoscopy can also be performed.
