Thanks for your question on Health Care Magic.
I can understand your concern.
Possibility of cancer is high in your father's case because he is smoker and having multiple lesions in
liver, lungs and
spleen.
So possibility of metastatic disease is more.
Biopsy is must for the confirmation of cancer.
So if biopsy is positive for cancer, he will be having stage 4 disease.
And stage for cancer is inoperable and incurable.
Palliative treatment in the form of
chemotherapy, radiotherapy, pain management and nutritional support is needed.
Life expectancy in such cancer is usually less than 2 years.
So better to first collect biopsy report and then start appropriate treatment.
Hope I have solved your query.
Wishing good health to your father.
Thanks.
