Why is it that small-cell lung cancer patients are 99% smokers?

Why is it that small-cell lung cancer patients are 99% 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.

Cancer (Definition)

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

How can I make a patient with lung cancer more comfortable?

How can I make a patient with lung cancer more comfortable?

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.

Why does the united states have so many lung cancer patients?

Why does the united states have so many lung cancer patients?

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.

My friend is getting weaker with lung cancer. Do most lung cancer patients die before a year?

Depends: The prognosis will depend on the stage and the type/ biology of the lung cancer. The type of treatments, the response to the treatments as well as patient's overall condition prior to the treatment started are also important factors. Depending to the above factors- patients with lung cancers can live from only a few /several months to several years or can be cured in the very early stage.

Lung cancer: Most patients with lung cancer esp stage 4 or advanced lung cancer carry a poor prognosis and survival is 12-15 months average with modern era chemotherapy. It can lead to progressive generalized weakness, fatigue and failure to thrive. Your friends stage and health status will determine his outcome. The role of chemotherapy is palliative;tarceva/iressa can work in nonsmokers w egfr mutations.

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 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".

What are the effects of large quantities of morphine on lung cancer patients?

What are the effects of large quantities of morphine on lung cancer patients?

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.

Lifespan for a lung cancer patients?

Lifespan for a lung cancer patients?

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.

Mucous and blood: You can have pieces of a lung cancer coughed up if it involves the airway, but usually it is mucous and blood. Even if tumor is present, you cannot pass cancer to someone else.

Lung (Definition)

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
