Thanks for writing to us .
You have not mentioned the size of the lump of skin on his neck side.
In all probability it looks like a Pedunculated wart/skin tag as it moves in all directions.It can be easily removed by a trained Doctor/surgeon under Local anesthesia
.Prior to doing it kindly get your BP checked. Routine investigations such as RBS/BT and CT done.
In another instance it could be a Sebaceous Cyst
with its blocked punctum pointing(Hard to touch as its filled with secretions and pointing). Similarly under local anaesthesia it can be surgically removed.
In both the cases the specimen has to be sent to Pathology Laboratory for a biopsy
report to ascertain the final Diagnosis.in all probability it can not be a malignancy/cancer.Get reassured.
Kindly consult a qualified General Surgeon
for further management.
Wish you a speedy recovery.
Dr Lt Cdr ASN Bhushan.
