Brief Answer: Most probably a vitamin B12 deficicency Detailed Answer: Hello sir and welcome. Thank you for writing to us. I doubt this is cancer, and the most common cause for such a presentation is a vitamin B12 deficiency. Other symptoms of a vitamin B12 deficiency can be: -Numbness or tingling sensation especially in the hands and feet -Pale skin -Bleeding gums -Weakness -Rapid heartbeat -Diarrhea or constipation -Weight loss -Mood changes and a few other symptoms. Other less common causes for a presentation similar to yours can be: -Wearing of braces -Tobacco chewing -Smoking -Vegetarian diet -Stress -Increased exposure to sun -Infections -Drinking or eating hot food or drinks and a few other causes. Cancer is not likely to be the cause at all sir. Please visit a doctor and request for a serum vitamin B12 test. Once a deficiency is confirmed, treatment with vitamin B12 supplements is recommended. I hope you find my response both helpful and informative. Please feel free to write back to me for any further clarifications, I would be more than happy to help. Best wishes.
