Thanks for your query.
You and all well wisher of your Boss should support and motivate him for proper treatment. To minimize the ill-effect of jaundice
and remaining body, stent
(tube) may be placed across the blockage of bile-duct cancer to facilitate bile flow to intestine. So jaundice, itching will be controlled.
Surgery is best treatment as it removes tumor
from body, provided tumor is well localised and this is assessed on CECT or MRI of abdomen.
To prevent further progression of tumor, usually chemotherapy
is advised but unfortunately in they have only small benefit compared to cancer of another organs. Newer chemotherapy drug are used in clinical trial with some more better results. To participate in trial, patient and family should be well motivated.
