What Percentage Of Lung Cancer Patients Are Smokers
Small cell Lung ca: Smoking tobacco significantly increases the risk of small cell carcinoma. Some hypothesize the impact of carcinogenic smoke on the central airways may be the primary mechanism of injury. The earlier in life a person starts smoking, the more often a person smokes, and the more years a person smokes, the greater the risk of lung cancer. ...Read more
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

Depends...: If they are in the end stages of lung cancer, they may be oxygen hungry and having oxygen at home may help. Making sure their pain is controlled is important too. At this stage, having a discussion with hospice services would be beneficial. For earlier stages, they may still be able to be cured and being supportive in their efforts is important. ...Read more

Smoking, radon...: 80% of lung cancer is caused by smoking, and there is often a 20 year lag period. As smoking decreases, so will lung cancer, but it will take time. Also, there are 3, 000 lung cancer deaths per year related to second hand smoke. Other causes include radon exposure. Also, rising incidence in lung ca in never smokers. These are molecular mutation factors. ...Read more

I thought non aggressive meant " non aggressive " so why would I see an article of a dr. Telling his patient with non agg/lung cancer that he only had 6-18 months to live how is that non aggressive?
I agree!: "aggressive" is a subjective, descriptive term almost arbitrarily used to define cancers; this term is never used by pathologists when codifying tumors. Many cancers have some features that would be considered aggressive and others that would not. Any cancer that could lead to someone's death in less than a year should not be described as "non-aggressive". ...Read more
Depends: If the patient is having pain, then often large amounts of morphine are needed to relive that pain. Sedation is possible but unlikely if the patient is still having pain. Itching and nausea are common at first but wear off. Constipation is universal and does not wear off. At very high doses sometimes toxicities such as muscle twitching can occur and may be a reason to switch to another pain med. ...Read more
Depends on stage:
In general, the most common forms of lung cancer when caught early are highly curable with surgery or stereotactic body radiation therapy.
Unfortuantely, most lung cancers are found at later stages when cure rates are very low.
Patients who are at high risk for lung cancer (i.e. tobacco smokers) should get screening chest CT scans to help find the cancer at early stages. ...Read more
Can you tell me which are the particles that a lung cancer patient emmit when he/she coughs or exhale?
Yes: I see why not. If it's a family member or a relative, they should be regarded as a team player. I've been told stories about people who were about to die but because of a child's presence in the house, they were able to motivate themselves enough to have their life extended for a few more years. ...Read more
What is outcome for patient with end stage metastatic lung cancer & extreme pleural thickening (benign)? Has to have injections to liquefy & extract.
Metastatic lung Ca: ...Is fatal in nearly all circumstances but the time course varies on tumor type, treatment and what organs are involved in the spread. The fluid in the chest may or maynot have cancer cells, but is likely malignancy associated at least. Repeat drainage procedures are reasonable. A catheter that remains in place is an option if it recurs frequently. Pleurodesis is option, but look at risk/benefit. ...Read more
Mesothelioma is a very serious disease.
Not an easy answer and depends on a number of factors (time and stage at diagnosis, age, surgical operability, other medical issues)

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
