Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Unknown and variable: Common sense says that the longer you smoke and the more cigs you smoke, the higher the risk for cancer (lung, throat, kidney, bladder, etc). How this applies to a particular individual, is not possible to guess. It may be decades for some, and a few years for others. If you smoke, STOP. Your risk may not drop as low as a never-smoker but should go down with time. ...Read more

Why take a chance?: Cigarettes cause more than 90% of lung cancers, and more than 90% of many other cancers.

Good question: But the problem is nobody can answer for sure. I guess it would require exposure for a few years but remember that cancer is seldom a one hit deal, a person may have predisposing factors that could lead to cancer with shorter exposure. Since you can't know for sure, why risk it? If you dip, quit right away. If you don't, stay that way. Spittin' in a can is kind of nasty anyways....Ugh. ...Read more
Not rare: 10-15% of lung cancers occur in non-smokers. 16-24, 000 americans die of lung cancer each year are "never smoked" patients. If you just took the "never smoked" group of lung cancer deaths, completely separate from the “smokers”, the "never smoked" lung cancer disease would rank among the top 10 fatal cancers in the United States. ...Read moreSee 1 more doctor answer
It is variable: There was an old number that was thrown around when I was in training, that if an individual smoked at least seven cigarettes, they had a >90% chance of becoming tobacco dependent. There are people who smoke "socially" and don't progress, but the vast majority will increase smoking to the average 30 cigarettes per day, and ultimately suffer the harms that smoking causes. ...Read more
None...: ...Even non-smokers get lung cancer. For people having the genetic machinery to get lung cancer (which isn't everybody), smoking increases the chances of lung cancer by an average of 50-fold. The problem is that we don't yet know what genes make smokers susceptible to cancer. It's best not to roll those dice at all. If you want help stopping, tell your doctor. There are many new options to help. ...Read moreSee 5 more doctor answers
Months: Median survival for all patients with brain metastases is 6 months. There are certainly lots of outliers on either side, with other factors helping to predict like overall burden of disease and general condition of the patient him- or herself. But even with the variation, survival beyond a year or so is not likely. ...Read moreSee 1 more doctor answer
Depends on the stage: There are 4 stages of esophageal cancer. Stage i-iii can be considered operable if the patient is of good physical condition. Tumor growing through the esophagus and into surrounding lymph nodes (regional) would be stage iii and still potentially operable. Tumor involving unresectable structures like the heart or bone, or that have metastastasized to distant organs (like brain) are inoperable. ...Read moreSee 1 more doctor answer

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
