There are many different things that can happen as a result of smoking. These are the risks that people take when they are deciding to smoke. There are number of different diseases that can occur as a result of smoking the scariest of which is lung cancer, let alone all of the other things that happen because of smoking such as premature aging as well as the onset of emphysema. However in some cases, when you do bring these diseases onto yourself, you will find that it is as a result of the smoking. It may be then that you will regret what you have done once you need to start having treatment for one of the many things that may have happened because of the smoking.
Once you have a disease because of smoking you will then need to do something to fight that disease, the first thing you should do is quit smoking which is not nearly as easy as it sounds. You will also need to go through the right regimen of treatments from your doctor in order to beat out the disease you are facing. If you are facing any type of cancer, you may need to go through rounds of chemotherapy, or different drugs and treatments. This will result in your being weaker and less able to do all of the things that you used to do on a daily basis.
However, you will not need to go and see the doctor nearly as often and have a less likely chance of needing to get breathing treatments and carry around an oxygen tank with you if you were to simply stop smoking in the first place. You would not have nearly the odds of getting cancer or having to go through all of the pain and suffering of chemo if you had simply not started smoking and were able to beat your addiction. However, now you are fighting two diseases and will in all likelihood be severely damaged by both because of the choices you made. So, quit and reduce your need for treatment.
