I took iron supplements of 100mg ferrous ascorbate for 4 days but since day 3 I experienced black stools and strange pain during bowel movement plus got hemorrhoids so I stopped it immediately after day 4. My hemorrhoids subsided after stopping the pills.
This was about a month ago but now when I google I read some linkage between iron supplement and cancer https://www.medicalnewstoday.com/articles/321515.php
Can I get colon cancer after taking supplements for just 4 days? I read symptoms of colon cancer and one of them is constipation I experience constipation once in a while but no blood in stools.
Screening for cancer is very expensive. From your experience do you think cancer could likely have happened during those 4 days?
