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

Iv smoked for about 10yrs. I'm 29 and I'm trying to quit. I'm wondering would it be rare for me to have lung cancer now.?

Iv smoked for about 10yrs. I'm 29 and I'm trying to quit. I'm wondering would it be rare for me to have lung cancer now.?

Try to quit anyway: Lung cancer from smoking isn't common at your age, but you've already permanently damaged the air spaces' elasticity and done some harm to the bigger airways. The sooner you stop, the better for your long-term health and ability to enjoy life. ...Read more

I have chest pain in the center, when ibow down. It is rare and it doesn't happen when I breathe. I have painin the back, like a circle. Is it lung cancer?

I have chest pain in the center, when ibow down. It is rare and it doesn't happen when I breathe. I have painin the back, like a circle. Is it lung cancer?

Unlikely: The pains that you feel need to be evaluated for what is causing them. Lung cancer is usually initially without much pain except for irritation of airway maybe but are found most of the time accidentally when looking for other things or as part of screening. Look at your risks for it and be screened and look for causes of the pain. If they happen to correlate then you find out. ...Read more

Both my uncle&my dad had lung cancer&lymphoma at the same time is this rare&could it be genetic? Many males have died from same for generations back!

Unknown: Many genetic predispositions exist that we can't identify.
However, lung cancer and leukemia together is unusual and suggests an environmental exposure. Were the victims smokers? Any specific occupation (i.e. Miners or coal workers or other?) i'd be much bore suspicious that your dad and his brother were exposed to something that led to the diseases. ...Read more

There is rare inherited mutation that gives you 1 in 3 lifetime chance of developing lung cancer even in non smokers. For someone with anxiety and lost mom to bac lung cancer should I test?

There is rare inherited mutation that gives you 1 in 3 lifetime chance of developing lung cancer even in non smokers. For someone with anxiety and lost mom to bac lung cancer should I test?

Which gene?: Egfr t790m's actual risk is unknown since nobody knows how many people without lung cancer carry the mutation. Even li fraumeni doesn't approach a 1/3 risk of lung cancer. And what would you do with this information if you had it? Hopefully you will always be a non-smoker. ...Read more

No symptoms and felt fine til they told me I had stage IV primary lung cancer / 2nd kidney cancer. Is it that unusual or rare for a person to live a long normal life without ever knowing they have it?

No symptoms and felt fine til they told me I had stage IV primary lung cancer / 2nd kidney cancer. Is it that unusual or rare for a person to live a long normal life without ever knowing they have it?

Lung cancer: About 35-40% patients when diagnosed with stage 4 nsclc do not have symptoms and signs of that and it is found as part of routine imaging or based on some very subtle and non specific signs and symptoms. ...Read more

Pain on touch on rt shoulder blade and when I bend my neck ~ 2 months. Chest CT clear, seldom pain in rt shoulder also. Am a smoker, lung cancer?

Pain on touch on rt shoulder blade and when I bend my neck ~ 2 months. Chest CT clear, seldom pain in rt shoulder also. Am a smoker, lung cancer?

Not likely: Not likely lung cancer. Sounds like muscle-skeletal pain, ie muscle sprain. If it persists for a few weeks then it warrants a doctor visit. Your ct scan is normal so this is less likely lung cancer. Lung cancer doesn't make you hurt upon touch. Smokers have a 20 fold risk of getting lung cancer. But that risk goes down significantly if they quit for about 5 years. ...Read more

My mom is a rare case right lung has nsclc removed one third of lung cancer free but the left one has sclc doc ordered six and half weeks of radiatio?

Reasonable: It is possible to have two different lung tumors at the same time. If there is no evidence of cancer outside the chest a combination of radiation and chemotherapy together would be the best proven therapy for the small cell lung cancer. ...Read more

If I smoked in my 20s then moved away from major cities and pollution at 40, is my risk for lung cancer high?

Higher than normal: Any time you smoke, you increase the risk of lung cancer. Even if you quit, the risk is still higher than someone who has never smoked.

But, this doesn't mean that you should, then, keep smoking. The sooner you stop smoking the better. And the issue of whether someone develops lung cancer or not depends on many factors in addition to smoking, such as genetic disposition, etxc. But stop smoking. ...Read more

What causes lung cancer?

Several causes...: But the most common correlation with lung cancer is smoking. Smoking alone will increase your risk of lung cancer by about 20 times by smoking one pack per day for twenty years. Other sources can be genetic (alpha-1 antitrypsin disorder), related to environmental exposures that are inhaled, or other less common reasons. ...Read more

How is lung cancer cured?

Multidisciplinary.: Several specialties are involved with treating a patient with lung cancer. A pulmonologist, oncologist, surgeon, radiation oncologist.

Not all cancers can be cured but they can be treated. ...Read more

How likely is surviving lung cancer?

How likely is surviving lung cancer?

Stage dependent: Odds of surviving lung cancer depend upon the stage (extent/spread) of the cancer at the time of diagnosis. A small tumor that is confined to the lung and has not spread to lymph nodes (stage 1) may be completely cured. An advanced tumor that is large and has spread to lymph nodes and other organs (such as brain/liver/adrenal glands) will be treated but will be challenging to completely cure. ...Read more

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
