### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
My son is six and has had a solid lump on his bone on the inside of his arm just above his elbow for a while, doc said it would go but a year on its still there and he has in the last couple of months been losing weight and seems to get infections easily and sores in the corners of his mouth could this be cancer?

### output:

HI. As your son is only 6 lumps on the bone is not likely to be due to cancer. I hope you have done at least X-ray of the affected part. X-ray may show this as an exocytosis- a benign condition. As for the sores at the corners of the mouth-this is called angular dermatitis and the cause is vitamins and folic acid deficiency. The root cause may be bad eating habits/ enterocolitis of some sort. This deficiency also causes the reduced resistance of the body giving easy infections and loss of weight. I would suggest such a patient to be first clinically evaluated by a Pediatrician and / or Pediatric gastroenterologist- HE would suggest further tests on examination and would advise multivitamins and folic acid in proper doses as also an antibiotic and metronidazole. I would advise you to give him It A one cap daily for 6 days and Clairol sachet one every week for 3 weeks. (if your Pediatrician does not write separately). This is going to help in a long run for a healthy baby. Give a shot of tablet for worms. Follow Orthopedic Surgeon for the growth at bone. I hope this helps you and your son to get a cure. Give a long term treatment and diet training is also a must (I know how 6-year-old are)
