First, changes must take place in a cell or group of cells that lead to uncontrolled division and growth. It takes at least 30 divisions of one cancer cell to create a tumor that is 1 centimeter in size about half an inch. That is the smallest size likely to be seen on an X-ray. It takes about three to six months for most lung cancers to double their size. Targeted therapies cannot cure lung cancer but they can slow its spread. Lung cancer does not usually cause noticeable symptoms until it's spread through the lungs or into other parts of the body.
This means the outlook for the condition is not as good as many other types of cancer. About 1 in 3 people with the condition live for at least 1 year after they're diagnosed and about 1 in 20 people live at least 10 years.
However, survival rates vary widely, depending on how far the cancer has spread at the time of diagnosis. Early diagnosis can make a big difference. Page last reviewed: 15 August Next review due: 15 August There are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms including: a persistent cough coughing up blood persistent breathlessness unexplained tiredness and weight loss an ache or pain when breathing or coughing You should see a GP if you have these symptoms.

Even this recommendation is not based upon any certain knowledge that these "spread" before that amount of time, but that a reasonably careful evaluation and diagnosis can and should be done within this time frame. Part of why it has been so difficult to show a health benefit to lung cancer screening is because of the vast differences in behavior from one cancer to another.
Screening may detect cancers that are not going to spread at all, while the more aggressive cancers have already spread by the time they are evident on screening studies. This has not been proven, but forms the basis for why we must await the results of large, well-designed screening trials. About 11 years ago, my sister, 73, had part of her lower left lung removed. She was doing fine until last year. Lung cancer was detected again in the same lung but at the top — too close to the heart to operate.
What are her chances of beating cancer again and being free and clear of it? We are worried about her. Thank you. The chances of surviving lung cancer are determined by the stage of disease, as well as the overall level of one's health. However, to tolerate "curative intent" chemotherapy and radiation therapy — in other words, treatment strong enough to attempt a cure — your sister would have to be in good physical health and without other serious or chronic conditions that interfere with her life.
Even then, chemotherapy can be difficult to tolerate at an advanced age. As always, the best person s to answer questions like these are the doctors who take care of your sister and know her personally. My cousin has been free from breast cancer for six years.
