5. Cancers
Cancer and the treatment for various types of cancer are known to trigger regular rates of digestive upsets, and might be the cause behind light brown stools: Experiencing light brown poop doesn’t mean that you have cancer, but it can be one of the warning signs – especially if you are a naturally higher risk for certain types of cancers and if you show any other symptoms or signs.
If you suspect that you might have cancer based on symptoms or signs that you have seen (or if you are just worried about your family history of cancers as compared to your own level of risk for developing it) then see your doctor as soon as possible.
A few simple tests and scans can tell you whether or not you have cause for concern when it comes to potentially developing cancer.
Occasionally, cancer treatments (such as chemotherapy) might trigger the same digestive effects.
