<s>[INST] I am an 87yr old lady and when I had to have my appendicitis out last summer a small cancer was found onn one of my kidney s i chose to leave it alone, and tthe Dr agreed with me, this year when I had a ultra sound it had grown about a centimeter again I chose to leave it alone , wondering if I did the right thing/ , [/INST] Thanks for your question on Chat Doctor. In my opinion you have done correct thing. At your age it is not advisable to diagnose malignancy and start chemotherapy and radiotherapy as these will not improve your life expectancy. Any treatment or work up is worth doing if it improves life expectancy and reduce suffering s. But this is not true for your age. Infact chemo and radiotherapy will harm you more than they are not routine medicines, they are highly toxic Chat Doctor. So I advise to leave it as it is and if you are symptomatic in future than go for palliative treatment. </s>
