Thank you for posting the query through Healthcare magic.
Your brother had a sore throat
only. But the fear of cancer is deep rooted in the minds of all of you. Because your father had a cancer in the throat. Your brother also might have started fearing the affection as cancer.
This fear of death is coined by the medical profession with the word 'cancer' and all the tumours or ulcers are explained to be having chance of turning to cancer. Therefore the sore throat with associated glands are taken as cancer by your brother and hence he is losing weight due to the fear of death.
Tendency to get throat infections, frequent sore throats, glandular enlargement are all constitutional peculiarities of your brother. What you have not included in the query is his mind and mental symptoms peculiar to your brother.
What he needs at present is a genetic and constitutional treatment. I can very confidently suggest you to go to an expert Homoeopathic physician who will take your brother's case in detail and will study his mind and body symptoms to prescribe a genetic constitutional remedy for him.
Please stop all further investigations. They will put him under greater mental tension and will make his condition worse. Reassure him that he will be cured of his disease through Homoeopathic method.
Or you can ask a premium question directly to me. I will send a case receiving format on request in which you can enter his whole case. Homoeopathy never treats his throat or glands. Homoeopathy cures him first and then all his diseases will be cured for good.
With Best Wishes, Dr C. J. Varghese, Homoeopath, email@example.com,
