Your symptoms of abdominal cramps, diarrhea
, rapid weight loss
points out to INFLAMMATORY BOWEL DISEASE(IBD), but history of Colon cancer
in your mother added to these symptoms strongly points towards colon cancer. Eventhough Barium enema
can diagnose both colon cancer and precancerous lesions like polyps in the colon it can miss small polyps, polyps higher up in the colon and early stages of colon cancer. Colonoscopy
is a better modality where small lesions can be detected, fortunately Biopsy
can also be taken by doing colonoscopy if lesions are seen and it can detect IBD also.
Given your history and presentation, its better getting yourself screened through Colonoscopy. You can also go for genetic testing
for the detection of gene mutations involved in carcinoma colon...
My wishes for your good health, Dr. Parthipan
