I see blood when i spot into the sink and i have minor throat pain, its not from my teeth as it happens way before i brush my teeth, my concern is thyroid cancer or throat cancer, could sharp foods or something else cause this im 28 dont smoke ?

Hemoptysis: Coughing up blood is called hemoptysis. Cancer is very unlikely. Thyroid cancer cannot cause blood in the respiratory tract. Throat or lung cancer rare at your age. Occasional scant hemoptysis is pretty common in people with chronic bronchitis. Are you a smoker? However, if this has occurred more than 2-3 times, it needs medical attention. Contact your doctor. Good luck.

Periodonal disease: You may have gingival inflammation and that risks loss of teeth. It would be prudent to see your dentist. Brush and floss regularly. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!

Bleeding: The rule of thumb is that any swelling and/or pain and/or as in your case, b bleeding, requires evaluation. Chances are much greater that your symptoms are caused by infection rather than cancer. As the bleeding you describe is common in patients with gum disease, see your Dentist. If cause is not of Dental original's your Dentist will then refer you to your Physician.
