My sister is on chemotherapy (folfox for metastatic colon cancer). Recent blood test shows high WBC (14, 000) and platelets (429). Is this okay?

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 more

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 more

My husband has colon cancer, his tumor and section of colon were removed yesterday. He has an elevated white blood cell count but no fever. Problem?

My husband has colon cancer, his tumor and section of colon were removed yesterday. He has an elevated white blood cell count but no fever. Problem?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, the elevated white cell count is likely a normal reaction to the trauma of surgery. If he has fever, discharge from the surgical site, pain at the surgical site, then you should consult your doctor promptly. ...Read more

Chronic constipation for years while on levothyroxine 50mcg. 25 y/o f. Type #1 on bristol. Thyroid blood work says it's controlled. Diet stinks. Past 2 weeks diarrhea, no appetite. Colon cancer?

Unlikely: There are many reasons for constipation and for diarrhea. Typically colon cancer presents with bloody stools or no symptoms. It's also unlikely in young people which is why colonoscopy screenings are recommended after age 50, unless you have significant risk factors like family history or other certain medical problems. If you have diarrhea for >2 weeks, you should seek medical attention. ...Read more
