Welcome to healthcare magic.
Reddish stool does not always indicate cancer.
Sometimes the food we eat also influence it.
At times undigested food particles may be seen as specks in the fecal matter which might look scary.
Since the symptoms you have mentioned was seen only today, you need not worry.
Keep looking at your stool and if you see the same on multiple occasions, you can have a stool test
done which will make clear whether it is blood or not.
Only if it is blood, then you need further tests.
If the symptom does not recur, you can wait till November when you come to India.
Hope that answer your question.
