50+ and smoke around 2-3 fags a day. Do i need a colonoscopy screening even if i don't have symptoms?

Yes: Regardless of your smoking history, you should have got your first screening colo as soon as you turned 50.

Mom is smoker ( around 2 fags a day). 52 yrs. Is a colonoscopy screening required for all smokers above 50 even without symptoms?

Not the smoking: It's the age. All people, non-smokers and smokers, should have colonoscopy initially at age 50 and then every 5 years. Pre-cancerous polyps don't have symptoms. I assume fags=cigarettes ...Read more

Can you give a list of all cancer screening tests for people who have no present symtoms of cancer, for example, a screening colonoscopy; how often?

Can you give a list of all cancer screening tests for people who have no present symtoms of cancer, for example, a screening colonoscopy; how often?

Only a few exist: Problem: cancer SLOW but usually, except for skin, DETECTED LATE. Thus bigger issue: realize that catching/stopping cancer is a key immune system function (controlled from brain), avoid foods which drive cancer (sugars), stay thin & keep up on science. Proven for men: check skin, mouth, thyroid & lymph nodes for growths, CBC, Electrophoresis, T. Markers, PSA (<1.0 ng/dL) & endoscopy>remove polyps. ...Read more
