Doctor said to my dad he have colon cancer but the biopsy result was ok it show that is just polip.His blood test was ok aswell.What we should do now?
Repeat colonoscopy: Unless the pathology report comes back on the polyp as showing malignancy, he will need to have a follow-up colonoscopy to look for new polyps in the future (1-3 years). The timing will depend on risk factors, such as a history of ulcerative colitis, strong family history, completeness of colonoscopy, biopsy findings. If the pathology shows cancer, he should see a colorectal or general surgeon. ...Read moreSee 1 more doctor answer
My sister is on chemotherapy (folfox for metastatic colon cancer). Recent blood test shows high WBC (14, 000) and platelets (429). Is this okay?
No worries.: High WBC can be due to many causes: infection, stress, steroid use, dehydration, or the use of growth factor (such as neupogen). If there is no evidence of infection, then there is nothing to worry about. High platelet count is not uncommon since it is a body's reaction to stress of any cause (platelet is an acute phase reactant). Again, nothing to worry about. All the best, hk. ...Read moreSee 1 more doctor answer

A friend has been told they have colon cancer, diagnosed via a tumour marker blood test, high cea, CT scan showed contained mass. Is this conclusive?
No, but...: But very suspicious for colon cancer. If your friend is similar in age to yourself a mass in the colon on ct scan is cancer until proven otherwise. And cea levels can go up for other reasons but, given the mass, they would strongly favor cancer. But to answer your question "no"... They are not definitive. You would need a piece of the mass under a microscope to prove definitively its cancer. ...Read moreSee 1 more doctor answer
I had a blood test done at my doctor and everything was normal. He said this means I probably don't have Colon cancer. Could I still have colon cancer?
FOBT is screen: Fobt is designed to test for blood in stool. Blood in stool may be due to any bleeding in the GI tract from the gums to the anus; and there are false positives also. If fobt is positive, colonoscopy is generally recommended to look of colon cancer. Fobt per se is not a diagnostic test for cancer, just blood in stool. ...Read moreSee 2 more doctor answers
