Brief Answer:
Polyps correlate with cancer.
Detailed Answer:
Hello XXXXXXX ji,
Thanks for posting your question.
If polyps of the size mentioned by you (3.5cm) were found in the colon, there is a likelihood that these polyps are cancerous.
Generally when we find polyps in the colon, we take a small piece of it to check if it has become a cancer, and I presume, that is what the doctors did in your father's case too.
Colonic polyps are considered as a pre-cancerous condition, so I would be looking for finding if there is indeed any cancerous change if I encounter such large polyps.
The staging of the condition can not be assessed with the information you have provided here. It would help me understand the condition better if you could share with me what was done to these polyps when found, were they removed? Were they then sent to lab for examining? Do you have the reports of any such test/biopsy?
Do you have the
colonoscopy report with you? If yes, can you upload it along with the query, so that I can see and opine accordingly.
Now coming to the second part of your query, that is related to
anemia.
Anemia for an year may or may not be related to the colonic polyps, however I would like to
stress the point that, it is highly likely that a person develops anemia if he has any type of cancer, and particularly if the cancer is originating from the intestines or stomach the anemia will be most commonly associated simply because of the chances of bleeding without ever noticing it.
The suspicion of
colon cancer should be high when there are very nonspecific symptoms or in case of
chronic constipation in elderly people, but as you said, your father was not having any symptoms, so it is quite possible that your GP did not think of the issue.
However, if the problem is only polyps which have been attached superficially to the colon, then they can be removed surgically, and based on the number of polyps and the cellular changes that are observed in the biopsied sample, a decision needs to be made about the exact course of action that needs to be taken, namely, excision of a part of colon or just removal of the polyps.
I hope I have answered your question adequately, I would happy to clarify any doubts you might have.
Please do write back with the requested details so that i may help you understand the problem better.
Wishing you all the very best.
Kindest regards.
