I have back problems and think I will take drogs tilI I die. Will surgery kill me or I will have lung cancer as a passive smoker ? What is the likelihood to die from what I told above?

It is a stage four so they are going to take lymph nodes as well, Just wondering how the surgery will go. This is not my year. I had a heart attack on March 1 and quadruple bypass on March 4 and now this. Yikes!

Iron deficiency anaemia, is a common finding in colon cancer, but how does it occur? What is the pathology behind it? Is it just because of occult blood loss?

Thanks

Hi, I heard that one of the ways to prevent melanoma is a systematic control of the skin by a doctor. I know that doctor does just a visual control, but I heard that there is a more powerful method. It is based on making photos of the birthmarks and comparison of the subsequent images (made with some time interval). I would like to know the name of the method.
