Welcome in H.C.M. for consultation
I have gone through your query regarding a tumor
in your throat which is diagnosed by C.T.scan only, now you have seen a black spot on it, you are confused regarding nature of tumor.
You have not told about your problems concern with this tumor as- difficulty in swallowing, breathing, is there any change in voice, have you ever notice any blood in your phlegm and did you feel any lymph
node in your neck etc. You told about black spot on tumor this indicates there may be secondary infection on tumor and slough may be form or there may be haematoma
But I am in favor of biopsy
of tumor which is really necessary for planing it's treatment.
