I should be able to avoid lung cancer by quitting smoking right?
I smoked from 2005 to 2010 but I smoked on and off (swishers filled with weed). I never smoked everyday and I probably have about 300 Blunts of weed in my lungs over 4 years. But every website that I read says lungs regenerate within 5 years for young people and 10 years for heavy old smokers. Im turning 26 and quitting forever. What do you think?

Will it eliminate the risk? No. Dana Reeve (Christopher "Superman" Reeve's wife) died of lung cancer and had never smoked. Will it lower the risk significantly? Yes.
2 :
Yup. Also smoking is your lifes biggest most idiotioc dumbest mistake.

I had an uncle who died on lung cancer and he never smoked a day in his life. It says right on the pack "Quitting smoking now greatly reduces serious risks to your health" It only means there less of a chance you can get it if you stop... but theres still a chance. So basically if you quit or not it don't matter, you still have a chance.. so smoke it up.

Rather you smoke or not...no one can aviod lung cancer...you can just lower your risk by not smoking.

obviously you've never read any information on biology to actually learn about what cancer is... The cells in your body constantly reproduce by splitting and thus forming new cells, they duplicate DNA to do this. Your genes are the sequence of DNA used to produce proteins. Proteins are strands of made of a set of 20 building blocks called amino acids that are strung together in a line. These amino acids attract and repell each other and so cause the strands to coiled and bunch up forming a specific shape. The protein is then able to interact w/ other proteins and chemicals and perform functions based on it's sequence and shape. A large ammount of the material in your body and that make up the cell are proteins and these play an important role in coltrolling everything your cells do and that takes place in them. Cells function by making proteins by reading then DNA as needed and destroying them when they aren't needed.. Ocassionally errors are made during the gene duplication and the wrong sequence gets encoded.Most mistakes will result in the cell dieing. However, some mistakes will allow the cell to live and continue to reproduce and thus pass on the error. Mistakes such as errors in the genes responsible for DNA duplication and checking that DNA is duplicated correctly (cells have DNA spell check systems), will lead to move errors. Errors can cause a cell to be able to continue without dieing or grow uncontrollably, or be able to live in different environment of the body and thus spread. Cancer is the condition of having errors in cells' DNA have caused cells to grow, reproduce, and behave in bad ways that are harmful to the body. In order for cancer to develop inwhich it would be a problem, it is likely to result from many errors in DNA: a combination in errors in DNA responsible for DNA replication, cell reproduction growth etc. Errors will probably occur naturally at a low rate, but if cells are in a stressed environment errors will ocurr more often. Things such as getting sun burned, exposure to radiation, and toxic/carcinogenic chemicals stress the cells and cause them to make more mistakes more often. Whenever you breath in particles, your lungs work to remove them. Your lungs do this by having mucus trap dirt and carry it out of lungs. Deep in your lungs however, the passage ways are too narrow for mucus to do that and so phagocytic cells "eat" or capture "dirt" particles and thus get remove them. When you smoke you breathe in lots of particles thus over working your lungs to remove them, which can cause the cells in your lungs to become irritated and inflamed, from your failure to remove the dirt, leading to them making more mistakes. Therefore, since you smoke there's a good chance in doing so you caused cells in your lungs to make errors in DNA replication. Such errors in your DNA may not might not do any harm, but you may continue to pass on from one lung cell to another. Getting cancer is all a matter of chance. By smoking you've increased your chances of developing cancer in the future. Since cancer results from a combination of errors in your DNA, you may not experience any effects until cells have accumulated the right (or rather wrong) combination of errors that cause your body harm. By smoking, you're more likely to have already accumulated some errors and so are more prone to get cancer. Since cancer is error in duplicating your DNA,it should be clear from grasping this concept, why it's so difficult to cure cancer. Also it should be understandable why there are so many types of cancer, because it can occur in all different types of cells all over your body and can effect different genes in your dna. Cancer is just chance and so all you can really do is reduce your risk, but avoiding things that are carcinogenic, and realize once, you've exposed you're self to carcinogenic situations, any damage you did will likely take with you. By lungs regenerating, they mean the health of your lungs will improve as the dirt gets cleaned out, but that won't reverse any precancerous damage you;ve already caused to lungs. You could not smoke for 60 and suddenly get lung cancer as a result of having smoked those 4 years. Seems like everything can cause cancer and everyone old I know gets cancer by the time they reach 80. My grandmother never smoked, but got 2nd hand from grandfather and has been battling lung cancer for a decade. This doesn't mean you should consider urself already screwed and just go ahead smoking, because u might not have done damage, but continuing would just increases risk, but I don't think you should miss out on life out of fear of cancer. Live a full life, just don't be unnecessarily reckless. I'd be more concerned about you're ambitions in life if u'r spending everyday smoking weed. read up on cell bio its interesting shiz
