What can one do to prevent on self from cancer ? is it true that strong immune system and healthy lifestyle protect one from the cancer?

Wish we have a definite answer for your question but unfortunately not. A healthy life style, give example no smoking or drinking, may be helpful in general but there are many patients who have lung or liver cancer even they never smoke or drink a day in their life and how to keep your immune system strong is also a big question. Take care.

Since a lot of cancers are genetic, there are no definite things that you can do to avoid cancer, but you can avoid foods and toxins that are known to be carcinogenic. You can avoid fatty foods and foods containing nitrites. Obviously avoid smoking and try to use sunscreen on a regular basis. There are no supplements which make any difference. Good luck.
